772459f15c Shape Keys now can be controlled with Vertex Weight groups as well!
Just fill in the name of a Vertex group in the Shape Panel, and this
Shape will then become blended with the reference Shape.

It is useful for example for a symmetrical modeled head, make a
copy of that Shape, and use two Vertex Groups to make it asymetric.
Of course the Shapes update nicely while Weight Painting.

Also new; since the Vertex group names reside on Object level, you might
want to copy these names to the other Objects that have the same Mesh.
That's a new button "Copy to Linked" in the first Edit Panel.

43d2904037 Cleanup and new features for vertex keys.
User doc: http://www.blender3d.org/cms/Shape_Keys.678.0.html

- The mixed use of "Vertex Key","Key" or "RVK" in Blender was a bit
confusing. Also a 'vertex key' assumes keys per vertex, which actually is
only a single key for the entire shape. The discussions on blender.org
forums all mentioned "Shape" or "Blend Shapes", which I think is an OK
name for a "Vertex Key" in the UI. :)

- Most work was code spaghetti cleanup. Doing shape-keys now nicely goes
via the depgraph and DerivedMesh. That then allows to have different
shapes per object, with the new "Pin" feature.
Objects now define what Shape is shown (ob->shapenr)

- Added a Shape Panel in the Edit buttons with the various options

- Fixed a lot of issues in the IpoWindow, with drawing the channels.
For example, deleting a key-line there caused the entire Relative option to
go wrong, same for moving the lines up/down.
Changing key-line order now reflects in order of channels. The active
Shape is drawn more clear now too.

- Noticed it doesnt work yet for curves/lattice. Need modifier advise!

0ce3341aaa Created a new sub-context ("tab") for all physics related button panels.
There we can find now Particles, Fields & deflectors, Soft Body and Fluids.
This also as preparation for more work on the particle side (becomes two
panels).

Also renamed panels, and made sure the name "Soft Body" is spelled every-
where the same!

It uses an icon as was designed long ago already. Needs some thinking...

98bd4615b5 On behalf of Mika Saari, the famous Unicode Font support!
Further information is available here:

http://wiki.blender.org/bin/view.pl/Blenderdev/UnicodeFont3D

Shortlist of features:

- Unicode character support for Font3D
- UI to select characters from Unicode character list
- UI to select Unicode table areas
- Optimized character loading (Load only those characters which are used
  in font object)

Please test extensively if it breaks anything, try also loading/saving
files, packing fonts, etc.

The official text regression file in the regression suite should be a
good start.

Thanks to mikasaari for this very useful addition!

1dba65e296 Roland Hess' Floor Constraint patch: https://projects.blender.org/tracker/?func=detail&aid=2993&group_id=9&atid=127
Minor modifications to simplify the code in evaluate_constraint.

The "Stick" feature will need more work as it gives bad results when skipping frames, jumping around on the timeline and when going backward in time.

Suggestion: Would be nice if it could use the local space too, not just global space planes.

a07394ef2c More text object fancyness, and fixes:
- "Flush" is now split into two seperate Alignment modes "Flush" and
   "Justify":

   - Justify does exactly the same as a normal word processor's justify
     function does, and in addition, it uses *whitespace* instead of
     *character spacing* (kerning) to fill lines. Much more readable.

   - Flush is pretty much the old Blender "Flush" mode - and as such it
     uses character spacing to fill lines. Just as Justify, this only
     works with at least one textframe.

 - Underlining for text objects. Not a lot to explain. New button "U" in
   the editbuttons, and CTRL-U as hotkey toggle underlining for newly
   entered characters or for the selection, just like CTRL-B/CTRL-I do for
   bold/italic.

   Underline height (thickness) and Underline position (vertical) can be
   set in the editbuttons.

   Implemented as CU_POLY polygon curves.

 - The B, U and i buttons (and the corresponding CTRL-B/U/I keystrokes)
   have been fixed to only affect *one* attribute at a time. Formerly,
   hitting CTRL-B when no other style was active, on a text portion with
   italics text, for example, would kill the italics and just apply bold.

   Now, these attributes always add or substract only, but do not
   replace the style.

 - In the past, there were bugs with material indices uninitialized, and
   thus crashes in the renderer with illegal material indices.

   Even though I assume they have been fixed, I've put in a check that
   checks (hah) if the material index of a character is illegal (bigger
   than ob->totcol), and then sets it to zero, and spits out a warning
   on stderr.

   If you see such warnings, please report and link to the .blend.

 - Bugfix: All alignment modes only worked if there were at least *two*
   lines of text in the text object. Fixed


There's now a regression test file for text objects, please add to the
corresponding repository:

85efe767f0 Integration of new IK lib features in Armature Poses.
Best is to forget yesterday's commit and old docs. New docs are underway...

Here's how IK works now;

- IK chains can go all the way to the furthest parent Bone. Disregarding
  the old option "IK to Parent" and disgregarding whether a Bone has an
  offset to its parent (offsets now work for IK, so you can also make
  T-bones).
- The old "IK to Parent" option now only does what it should do: it denotes
  whether a Bone is directly connected to a Parent Bone, or not.
  In the UI and in code this option is now called "Connected".
- You can also define yourself which Bone will become the "Root" for an IK
  chain. This can be any Parent of the IK tip (where the IK constraint is).
  By default it goes all the way, unless you set a value for the new IK
  Constraint Panel option "Chain Lenght".
- "Tree IK" now is detected automatic, when multiple IK Roots are on the
  same Bone, and when there's a branched structure.
  Multiple IK's on a single chain (no branches) is still executed as usual,
  doing the IK's sequentially.
- Note: Branched structures, with _partial_ overlapping IK chains, that don't
  share the same Root will possibly disconnect branches.
- When you select a Bone with IK, it now draws a yellow dashed line to its
  Root.
- The IK options "Location Weight" and "Rotation Weight" are relative,
  in case there's a Tree IK structure. These weights cannot be set to
  zero. To animate or disable IK Targets, use the "Influence" slider.
- This new IK is backwards and upwards compatible for Blender files.
  Of course, the new features won't show in older Blender binaries! :)

Other changes & notes;

- In PoseMode, the Constraint Panel now also draws in Editing Buttons, next
  to the Bones Panel.
- IK Constraint Panel was redesigned... it's still a bit squished
- Buttons "No X DoF" is now called "Lock X". This to follow convention to
  name options positive.
- Added Undo push for Make/Clear Parent in Editmode Armature
- Use CTRL+P "Make Parent" on a single selected Bone to make it become
  connected (ALT+P had already "Disconnect").

On todo next; Visualizing & review of Bone DoF limits and stiffness

dfb654ba60 Huge commit, but not much features... had to shuffle a lot of code around.
Main target was cleanup of editconstraint.c and removal of the ugly
ob->activecon (active constraint channel), which was set by the "Show"
button in the Constraint Panel.
Better is to introduce an 'Active Constraint' itself, which stores in
the Constraint itself. By using this setting, and by checking the active
Bone, the UI can update reliably now. This only shows now in IpoWindow
btw (for constraint ipos). The active Constraint is drawn in the Buttons
with a slightly brighter backdrop. Any action in that Panel selects a
constraint now (even click in backdrop).

So now we have pose channels & constraint channels nicely behaving. Now the
darn Action channels... :)

Further in this commit:

- interface.c: Button ROUNDBOX now does button callback too.
               Button NUMSLI didn't do the callback on a click only

- Cleaned up include files in yafray, got annoyed it compiled over all the
  time.

- removed unused variables from Constraint struct

9a105042fc At last! B-bones now deform. :)
This works pretty nice for better control over the curvature of any bone
deform. No need to give Bones (vgroups) large influence, just add a coupleof B-bone segments.

Two notes;
- The Bone property "Segments" defines if a deform happens as a 'B-bone'.
  The drawtype B-bone is just for display in 3d window.
- A B-bone also deforms (bends) in Rest-position, if there's a joint that
  creates a curved Bone. Therefore, best results you get by creating a
  rest-position with straight joints. Or, if you prefer a slightly bended
  restposition (for a spine or so), make sure the Mesh model is *not*
  curved, the B-bone will do this for you.

Also added: proper events on changing buttons for Bones, like "Segm" or
"Dist" etc.

7804860cf6 - added mesh_strip_loose_faces, works in conjunction with make_edges
to get rid of faces with MFace.v3==0
 - change all Mesh's to have ->medge now. This is forced by make_edges
   on readfile, and in the various exotic important routines, and on
   conversion back in python.
 - make python NMesh structure always have medges now (needs testing)
 - with above two changes it is guarenteed that mf->v3 is never ==0
   in main blender code (i.e., all MFace's are actually triangles
   or quads) and so I went through and removed all the historic tests
   to deal with MFace.v3==0. Equals lots of deleting, I am in heaven!
 - removed MEdge edcode flag, no longer needed
 - added experimental replacement for edge flag system

Still are some inconsistencies in FACESELECT mode edge drawing to
be ironed out.

NOTE: This commit adds an experimental edge flag calc system, based
on 10-seconds-of-thought algorithm by yours truly. Would appreciate
feedback on how this system works, esp compared to old one and esp
on complex or interesting models.

To Use: New system is enabled by setting G.rt to a value between
1 and 1000 (Value of 0 uses old system). Value 1000 is reserved for
"auto" edge, which is more or less identical to old system but also
makes sure that at least 10% of edges are drawn (solves errors for
super subdivided meshes). Values between 1 and 999 act as percent
(out of 1000) of edges that should be drawn, starting with "most
interesting" edges first. Please try it and comment!

4fed035618 Weight Paint & Vertex Paint goodies;
- New: "Spray" is an option now. This used to be the only available vertex
  painting method, while holding the mousebutton and move mouse, it keeps
  applying (adding, blending) the color.
  Disabling "Spray" will give more a 'paint' effect, only applying the
  maximum what you indicated to be painting.

- Weight Paint now offers all options Vertex Paint has. This includes "Add",
  "Mult", "Sub", and "Filter". And of course the "Spray", which is default
  off btw.
  Since Weight Paint might need totally different settings, they are stored
  separate from Vertex Paint options.

- Renamed the weird "Area" and "Soft" options into something that tells what
  it actually does (Even tooltips were wrong).
  Area -> "All Faces", option to have all Faces inside the brush being
     painted on. Disabling this only paints on the face under the cursor.
  Soft -> "Vertex Dist", option that uses distances from cursor to vertex
     to calculate the effect. Disable it to only paint per-face.
  If someone knows better names... go ahead! :)

- New WeightPaint option in the Panel: "Clear", which removes reference
  to this deform group from all vertices.

- Removed code that deleted 'deform vertices' from Mesh on exit editmode,
  when vertexgroups were empty. This just worked against you... you could
  not paint on empty groups.

- Made Weight Paint painting much nicer. The way it applied values was very
  harsh without good transitions. Mainly because it didn't use the
  "Vertex Dist" option, but also because it applied colors 3 or 4 times per
  vertex (tria/quad).

- Weight Paint undo now restores on a 2nd Undo.

- Vertex Paint Panel button "Clear" didn't work even.

2abd79b491 - readded DL_VERTS type to store lattice deformed verts
- new feature, twiddled with lattice resizing to try to maintain
   existing vertex changes... much nicer than just resetting the
   lattice if you decide you need more detail in the lattice.
 - modifiers work with lattices now. yes, that does mean you
   can make a chain of lattices effecting each other 8 miles
   long.
 - some cleanup of softbody code, was rather splintered and call
   path was twisted and confusing. reworked main object step
   routine to do things in a more obvious and consistent manner
   and without duplicate code
 - added ob->softflag OB_SB_RESET instead of sbObjectReset
   call
 - modifier changes reset softbody now
 - moved curve_getVertexCos/curve_applyVertexCos into curve.c
 - update curve modifier eval to work with virtual modifiers
 - update modifier apply to work with curves/surfs
 - update make parent to also recalc object data

NOTE: Although you can turn SB on for curve/font objects at the
moment it doesn't really work because they call deform in
multiple steps and this confuses SB. Not sure how to deal with
atm.
2005-08-15 10:30:53 +00:00
9030e5f686 - added eModifierTypeFlag_RequiresOriginalData for modifiers that
can only follow deform (for example, they store mesh vertex
   indices)
 - added ModifierType.foreachObjectLink for iterating over Object
   links inside modifier data (used for file load, relinking, etc)
 - switched various modifiers_ functions to take object argument
   instead of ListBase
 - added user editable name field to modifiers
 - bug fix, duplicate and make single user didn't relink object
   pointers in modifier data
 - added modifiers to outliner, needs icon
 - added armature, hook, and softbody modifiers (softbody doesn't
   do anything atm). added conversion of old hooks to modifiers.

NOTE-THE-FIRST: User name field is not initialized on loading 2.38 files
so if you have saved stuff with a cvs blender you will see blank names.

NOTE-THE-SECOND: Since modifiers aren't evaluated yet for non-Mesh
objects, hooks for lattices and curves are broken. Don't updated if
you actually, say, *use* Blender.

NOTE-THE-THIRD: Old hooks used a quirky weighting system during
deformation which can't be extended to modifiers. On the upside,
I doubt anyone relied on the old quirky system and the new system
makes much more sense. (Although the way falloff works is still
quite stupid I think).
2005-08-10 22:05:52 +00:00
932e958816 made weight paint panel full width ( still try to understand that X,Y system panels use )
replaced senseless 0 opacity  with 1/8 opacity
2005-08-08 21:56:52 +00:00
8319b3d1fa - modifier UI update (aka, find the modifier buttons!!)
- moved back to editing buttons, where life is now cramped... switched
   to constraint style foldout panes, still a WIP. In particular not
   sure what buttons should be in header (and if current toggles stay
   in header if they should also be in an expanded pane). Also need
   new icons for move up/move down (and drag and drop would of course
   be nice). Finally current plane is to make it so modifiers will
   expand out in modifier pane for horizontal orientations instead of
   just going down down down to goblin town.
 - added error field to modifiers that is displayed in UI, need to have
   some way for modifiers to return errors back to interface (esp. important
   for python)
 - tweaked cage determination and handling, currently the editmode cage
   is determined by last modifier with OnCage set that is preceeded completely
   by modifiers that support mapping or are disabled in editmode. it is
   kinda confusing, but the interface only lets you toggle OnCage for modifiers
   that support it - it just might not be clear all the time why you can't
   toggle a certain modifier OnCage.
 - update displistmesh_copy to only copy edges if non-NULL

There is a display bug that already existed but is more obvious with
new modifiers where parts of the pane get drawn in a different area
after toggling editmode. It has to do with drawing parts of the interface
using GL instead of 100% buttons. I try to keep my grubby little toes
out of the interface code so this can wait for Ton to return.
2005-08-04 07:25:43 +00:00
e331e68b57 - added ModifierData flag, is modifier enabled in editmode
- added modifier type flag: should modifier be enabled by default for
   active in editmode
 - added subsurf "debug incremental" option instead of G.rt==52 (it becomes
   a slightly useful feature now for debugging how well a modifier works
   with incremental subsurf... maybe important for future python modifier
   developers)
 - shuffled modifier button layout just to keep people guessing
 - switched back to drawing editmesh face centers not through derivedmesh,
   I didn't think this one through, forgot that centers were also used for
   selection. have to think about what to do about this, should be either
   (a) don't draw centers with a cage active (optimal mode) or (b) come up
   with api to draw centers through derivedmesh and also handle selection.
 - changed recalc_editnormals to also follow the len(no)==0.0 use vertex
   co convention
2005-07-23 19:15:08 +00:00
33709bf6e2 - shuffled editmesh derived function name/function
- added ModifierTypeInfo.freeData function
 - added modifier_{new,free] utility function
 - added ccgSubSurf_getUseAgeCounts to query info
 - removed subsurf modifier faking (ME_SUBSURF flag is no
   longer valid). subsurf modifier gets converted on file load
   although there is obscure linked mesh situation where this
   can go wrong, will fix shortly. this also means that some
   places in the code that test/copy subsurf settings are broken
   for the time being.
 - shuffled modifier calculation to be simpler. note that
   all modifiers are currently disabled in editmode (including
   subsurf). don't worry, will return shortly.
 - bug fix, build modifier didn't randomize meshes with only verts
 - cleaned up subsurf_ccg and adapted for future editmode modifier
   work
 - added editmesh.derived{Cage,Final}, not used yet
 - added SubsurfModifierData.{mCache,emCache}, will be used to cache
   subsurf instead of caching in derivedmesh itself
 - removed old subsurf buttons
 - added do_modifiers_buttons to handle modifier events
 - removed count_object counting of modifier (subsurfed) objects...
   this would be nice to add back at some point but requires care.
   probably requires rewrite of counting system.

New feature: Incremental Subsurf in Object Mode

The previous release introduce incremental subsurf calculation during
editmode but it was not turned on during object mode. In general it
does not make sense to have it always enabled during object mode because
it requires caching a fair amount of information about the mesh which
is a waste of memory unless the mesh is often recalculated.

However, for mesh's that have subsurfed armatures for example, or that
have other modifiers so that the mesh is essentially changing on every
frame, it makes a lot of sense to keep the subsurf'd object around and
that is what the new incremental subsurf modifier toggle is for. The
intent is that the user will enable this option for (a) a mesh that is
currently under active editing or (b) a mesh that is heavily updated
in the scene, such as a character.

I will try to write more about this feature for release, because it
has advantages and disadvantages that are not immediately obvious (the
first user reaction will be to turn it on for ever object, which is
probably not correct).

28a1e8277b Result of 2 weeks of quiet coding work in Greece :)
Aim was to get a total refresh of the animation system. This
is needed because;
- we need to upgrade it with 21st century features
- current code is spaghetti/hack combo, and hides good design
- it should become lag-free with using dependency graphs

A full log, with complete code API/structure/design explanation
will follow, that's a load of work... so here below the list with
hot changes;

- The entire object update system (matrices, geometry) is now
  centralized. Calls to where_is_object and makeDispList are
  forbidden, instead we tag objects 'changed' and let the
  depgraph code sort it out
- Removed all old "Ika" code
- Depgraph is aware of all relationships, including meta balls,
  constraints, bevelcurve, and so on.
- Made depgraph aware of relation types and layers, to do smart
  flushing of 'changed' events. Nothing gets calculated too often!
- Transform uses depgraph to detect changes
- On frame-advance, depgraph flushes animated changes

Armatures;

Almost all armature related code has been fully built from scratch.
It now reveils the original design much better, with a very clean
implementation, lag free without even calculating each Bone more than
once. Result is quite a speedup yes!

Important to note is;

1) Armature is data containing the 'rest position'
2) Pose is the changes of rest position, and always on object level.
   That way more Objects can use same Pose. Also constraints are in Pose
3) Actions only contain the Ipos to change values in Poses.

- Bones draw unrotated now
- Drawing bones speedup enormously (10-20 times)
- Bone selecting in EditMode, selection state is saved for PoseMode,
  and vice-versa
- Undo in editmode
- Bone renaming does vertexgroups, constraints, posechannels, actions,
  for all users of Armature in entire file
- Added Bone renaming in NKey panel
- Nkey PoseMode shows eulers now
- EditMode and PoseMode now have 'active' bone too (last clicked)
- Parenting in EditMode' CTRL+P, ALT+P, with nice options!
- Pose is added in Outliner now, with showing that constraints are in
  the Pose, not Armature
- Disconnected IK solving from constraints. It's a separate phase now,
  on top of the full Pose calculations
- Pose itself has a dependency graph too, so evaluation order is lag free.

TODO NOW;

- Rotating in Posemode has incorrect inverse transform (Martin will fix)
- Python Bone/Armature/Pose API disabled... needs full recode too
  (wait for my doc!)
- Game engine will need upgrade too
- Depgraph code needs revision, cleanup, can be much faster!
  (But, compliments for Jean-Luc, it works like a charm!)
- IK changed, it now doesnt use previous position to advance to next
  position anymore. That system looks nice (no flips) but is not well
  suited for NLA and background render.

TODO LATER;

We now can do loadsa new nifty features as well; like:

- Kill PoseMode (can be option for armatures itself)
- Make B-Bones (Bezier, Bspline, like for spines)
- Move all silly button level edit to 3d window (like CTRL+I = add
  IK)
- Much better & informative drawing
- Fix action/nla editors
- Put all ipos in Actions (object, mesh key, lamp color)
- Add hooks
- Null bones
- Much more advanced constraints...


Bugfixes;

- OGL render (view3d header) had wrong first frame on anim render
- Ipo 'recording' mode had wrong playback speed
- Vertex-key mode now sticks to show 'active key', until frame change

97df61a7e5 Initial commit for new text object.
Important notes:

 - Full compatibility with old text objects not fully restored
   (word spacing will be 0.0, need to set it manually to 1.0), will
   either need version upgrade to 238 or a hack. Will check.

 - lorem.c (about to be committed) contains BF copyright notice, but as
   BF did not exist a few hundred years ago, probably best to remove it :)

 - If you notice any cross-platform issues (especially beloved windows),
   please report

 - A few tiny warnings left, I will fix those issues still.

The rest has been said already - so have fun testing. And please do!

ec45bfc5b1 Second and final commit for this version of the yafray export code (probably, you never know
of course...)

Not quite complete, but due to lack of time as good as it will get for now.

From the previous commit, forgot to report that basic fog is supported as well. Though because I had not much time to complete the code, it is sort of unfinished, and you will have
to tweak parameters specifically for yafray again. It uses only the world horizon color, and
only uses the Blender mist distance setting.

Textures now support checker clip mode.

Fixed possibly all 'duplilist non-empty' errors, though it could hide the real cause of the
error.

AA is no longer enabled automatically for certain GI quality settings, I thought it best to
leave it to the user to decide.

SkyDome GI mode now supports cache as well. There is a new option in the GI quality menu 'Use
Blender AO settings', which will as it says use the most important AO settings for the
skydome parameters. The only AO parameters used are 'Samples', 'Dist' and the random sampling
switch, which unlike in Blender you might want to use more often, since the QMC sampling used
in yafray can result in visible patterns or a dithering type look. 'Random' is not completely
random in yafray however, it is actually jittered (stratified) sampling.
Using an occlusion cache, doesn't necessarily mean that you will always get much shorter
render times. As with 'full' GI and cache, one problem is bumpmaps, when using bump (or
normal) maps, the sampling will be much more dense, using lots more rendertime.
As a temporary fix there is a button 'NoBump', but this also has the side effect that in
areas of total indirect light (or when used with SkyDome cache) no bumpmapping will be
visible. It is therefor best used with some direct light as well.
For SkyDome with cache, and strong bumpmapping it might actually not make much difference,
since for low distance values you can usually get away with low sample values as well.

The entire material panel is now replaced by another panel to show only the parameters
important to yafray and add some new ones as well.

Since lots of users (especially yafray beginners) have had problems getting certain material
aspects right, there is now a material preset menu available to hopefully solve some of the
most common "How do I do this? It doesn't work!" questions seen in various forums.
Choosing an option from this menu will set the required parameters to default
values for yafray, and you can work your way from there to tweak it something you want.

Most buttons are copies of the same Blender parameters, with some variations. Just like
Blender 'Ray Mirror' enables reflection, 'Ray Transp' enables refraction. You can use
'ZTransp' for materials that have texture maps with alpha channels.
Again, same as Blender 'rayMir' sets the amount of reflection. Next button 'frsOfs' however
controls fresnel offset, meaning that when this is set to 1, you will get no fresnel effect
and when set to 5, reflection is totally determined by fresnel, which is important for
realistic glass/metals/etc.
IOR is self-explanatory (...), same as Blender.
When you have 'Ray Transp' enabled, the blender 'filter' button will appear next to the IOR
button. This has the same effect as in Blender.

Below that there are some new parameters, 'Ext.Color' sets the extinction color for
transparent materials. Usually, in real transparent materials, light loses some of it's
energy the further it has to travel through the object. This effect can be simulated with
this parameter. Thing to look out for is that it specifies the color which will be
REMOVED after traveling through the object. What this means is that say you have a clear
white glass sphere, and set the extinction color to a strong blue, the result will be a
very yellow object when rendered.

Next to the color sliders, there is another set of three parameters, with which you can
enable color dispersion for transparent objects. 'Pwr' sets the amount of dispersion,
the higher, the more dispersion (the more colorful the result).
(For real world materials, this number can be found or derived from data in various glass catalogues)
The 'Samples' button below that sets the number of samples used, minimum values are around
7-10, and for very strong dispersion you might need a lot more.
As usual, this also means an increase in render time of course, but to simulate
realistic materials, you shouldn't really need more than 25 samples.
In addition to that, when using low sample numbers, but to still get a good spread of colors,
you can enable the jitter button, but this will also add noise.

Point/soft(point with shadowbuffer) or sphere lights (light with radius), have a new option
to add a simple glow effect, so that lights can be made visible.
NOTE: just like spotlight halo's, glow is not visible against the background, there must be
another object behind it. Simplest solution is to use a large black shadeless plane behind
your scene.
The glow intensity can be set with the 'GlowInt' parameter (use very low values around 0.01
even lower), and you can choose from two different types with the 'GlowType' button (which
don't look much different, but type 1 is probably better, type 0 faster).

And that's it, with apologies for the still missing features and
full support in general, but this will have to do for now.

42126cb5fc Added baking for softbodies.
Works as follows;
- press the 'show bake settings' button (no space left... :)
- define start/end frame for bake, and an interval step.
  The baked result interpolates nicely (Bspline, 4 keys) so in general a
  step size of 2 or 3 still gives OK results.
- Press "BAKE". This will do a full animation + playback. Press ESC if it
  you don't want it.

Once Baked, the BAKE button becomes a FREE BAKE. As reminder the softbody
buttons get blocked with error() menu.

This saves OK in a file. Renders any frame, including fields and moblur.
You can also set a "Timeoffs" for the softbody. And yes, this should be
in the NLA once... :)

NOTE! With this commit, files saved with the old (first commit) version by
Jens Ole won't read the settings back... he stored all sofbody variables in
Object, which was moved to a new struct when I did my first commit on SB
(over a month ago)

Also note that I moved particle deflecting & softbody to a new include.

7fa7826da7 The zblur plugin (aka as DoF) integrated in render. Compared to patch
submitted by Alexander, changes/improvements are:

- Moved to new Panel in Scene buttons "Post Effects". Together with other
  postprocessing options, such as Edge render. It is also not called DoF,
  this because that's a bit pretending too much then. It's a zblur still!
- Made it render Alpha as well
- Made it use and deliver float buffers
- Huge cleanup of zblur.c code, was very messy. It was alling things in render
  code without need even (win matrices, transform faces, etc)
- Fixed errors in using Z values (zbuffer is signed int)
- Removed very weird gamma corrections for front/back half
- Tweaked gaussian table, allow variable 'Sigma' to be set for gauss curve
- Didn't copy 'auto focus' yet. Use of this is very limited, and gives
  false expectations, nor works for rendering anims with deamons well.

Main issue remains: it's not a very advanced feature... I still doubt
very much if this deserves to be released. Spent 2 days on trying to get
the key issues solved, with not much results.

- gauss filter code has weird side effects on large blur size
- having unsharp (blurred) in front also blurs what's around in back.
  only blurred in back with sharp in front works a little bit
- severe aliasing errors... also due the code splitting in 2 halves
- doesnt work with unified yet
- won't work for halos, spot halos or transparant faces

Anyhoo... It was promised to be committed, so now artists can play with it.
Who knows it's useful after all, or some fixes can be implemented. :)

7943f7990e Softbody:
- Added browsing for vertex group for "Goal" in SoftBody buttons.
- Means the default name "SOFTGOAL" isn't needed anymore
- temporally, on file read, the "SOFTGOAL" vertex group is set, if exists
- removing vertex group possible too
- changed softbody.c code to use this
2005-04-16 14:01:49 +00:00
90df59630e More softbody goodness;
- Added Softbody effect for Lattices (not too useful yet without
  vertexgroups though)
- Added default vertex "goal" value + button, to be assigned when no
  vertexgroup exists (or vertex isn't in the group)
- Made softmin and softmax work as documented (defining min and max range)
- made changes in buttons send 'update' signal to softbody

And:

- added Nkey Properties to show lattice coordinates
2005-04-02 19:52:32 +00:00
f0a8a93292 - removed USE_CCGSUBSURF define (always on now)
- added G.editMesh->derived pointer... idea is to use this
   for mesh derived from editmesh instead of Mesh->derived (as the
   derived mesh tends to vary depending on what it came from).

   This part could be cleaner, also there may problems with it not
   being invalidated correctly.

 - And most importantly: In case people were beginning to worry all
   these edits were just crazy zr stuff, the big point comes about:
   Incremental subsurf calculation is now enabled. This gives massive
   speed improvements when editing a large mesh.

   For the eye-candy happy: try setting G.rt==52 before entering editmode
   and the edges and vertices (in optimal mode) will switch to displaying
   visually the age since a region has last been calculated. Lots of
   fun!

912ef80bdc big softbody commit
some vertex group , weight painting stuff too
/me crosses fingers it does not break anything
2005-01-12 22:28:13 +00:00
610cec55c7 Biiig commit! Thanks to 2-3 weeks of cvs freeze...
Render:
- New; support for dual CPU render (SDL thread)
  Currently only works with alternating scanlines, but gives excellent
  performance. For both normal render as unified implemented.
  Note the "mutex" locks on z-transp buffer render and imbuf loads.
- This has been made possible by major cleanups in render code, especially
  getting rid of globals (example Tin Tr Tg Tb Ta for textures) or struct
  OSA or using Materials or Texture data to write to.
- Made normal render fully 4x32 floats too, and removed all old optimizes
  with chars or shorts.
- Made normal render and unified render use same code for sky and halo
  render, giving equal (and better) results for halo render. Old render
  now also uses PostProcess options (brightness, mul, gamma)
- Added option ("FBuf") in F10 Output Panel, this keeps a 4x32 bits buffer
  after render. Using PostProcess menu you will note an immediate re-
  display of image too (32 bits RGBA)
- Added "Hue" and "Saturation" sliders to PostProcess options

- Render module is still not having a "nice" API, but amount of dependencies
  went down a lot. Next todo: remove abusive "previewrender" code.
  The last main global in Render (struct Render) now can be re-used for fully
  controlling a render, to allow multiple "instances" of render to open.

- Renderwindow now displays a smal bar on top with the stats, and keeps the
  stats after render too. Including "spare" page support.
  Not only easier visible that way, but also to remove the awkward code that
  was drawing stats in the Info header (extreme slow on some ATIs too)

- Cleaned up blendef.h and BKE_utildefines.h, these two had overlapping
  defines.

- I might have forgotten stuff... and will write a nice doc on the architecture!

d7c8ff725a Bug #1909
When choosing "render engine" in Scene Buttons, the newly added or removed
Panels didn't invoke a re-alignment event yet.
Also added code that inserts new panels as good as possible on their
previous locations. This works reliable for 1 new panel, not for more, this
because a Panel only stores its old location, not the locations of all
Panels in a given configuration. Consider that minor issue...

d5e0c065bc Version 1.0 of the new Outliner
The outliner is a hierarchical diagram displaying a list of data in Blender
and its dependencies. The 'databrowse' doesn't really show it, and Oops is
too chaotic still. And most of all, the former two don't offer much tools.

After discussions on irc, Matt came with this design proposal;
http://mke3.net/blender/interface/layout/outliner/
Which is closely followed for the implementation.

The current version only shows all 'library data' in Blender (objects,
meshes, ipos, etc) and not the 'direct data' such as vertex groups or NLA.

I decided to make it inside the Oopw window, as an option. You can find the
option in the "View" pulldown, or directly invoke it with ALT+SHIFT+F9
Here's a quick overview of the Outliner GUI:

- Header pulldown has options what it can show (Visible = in current layers)
- click on triangle arrow to open/close
- press AKEY to open/close all
- Leftmouse click on an item activates; and does based on type a couple of
  extra things:
  - activates a scene
  - selects/activates the Object
  - enters editmode (if clicked on Mesh, Curve, etc)
  - shows the appropriate Shading buttons (Lamp, Material, Texture)
  - sets the IpoWindow to the current IPO
  - activates the Ipo-channel in an Action
- Selected and Active objects are drawn in its Theme selection color
- SHIFT+click on Object does extend-select
- Press DOTkey to get the current active data in center of view


TODO;
- rightmouse selection; for indicating operations like delete or duplicate
- showing more data types
- icon (re)design...
- lotsof options as described in Matts paper still...
2004-10-06 18:55:00 +00:00
37f57288cb Lot of code... 2 new features:
1) Curve deform
http://www.blender3d.org/cms/Curve_Deform.392.0.html
Works simple as expected, but keep track of the rotation axis
in F7 buttons (Track X Y Z)
Only Mesh deform supported now.

Code changes:
- centralized deformation calls in curve_modifiers() mesh_modifiers()
etcetera. Here also other effects can be added like wave. Now the
evaluation order is fixed, but should become optional. It also doesnt
use the Displist anymore as deform-input. That latter part is unfinished
yet.
This code also is used for Hooks and will be needed for softbody

- made convention stricter that displists are being checked on in
drawobject(), this to prevent routines to make new displists recursively
(like armature does). Now a freedisplist() is sufficient to signal that
a new displaylist should be made.

2) Object Hooks
http://www.blender3d.org/cms/Object_Hooks.391.0.html
Support for Hooks is added to Mesh, Lattice, Curve and Surface objects.
For Armatures this would require some more work & research.
Main goal for this feature is to provide quick & simple access to the
underlying geometry in Objects on Object level, supporting hierarchies and
Ipos etc.

Read today's meeting minutes for a description.

Bjornmose: We'll need some example and screenshots for the dev pages of blender3d.org. If you can do some, neat, if not, I'll do them.

Matt, Emilie and Chris: Please review UI addition. Pixel alignement and all that fun stuff has not be overly looked for (though I did some cleaning by adding alignment blocks).

fe9336eb88 Work on creases editing.
- while editing creases (SHIFT+E) it works like scaling now (towards or
  away from center selection).
- ESC while crease edit now works.
  (note; doesnt fit in Trans structs...)
- button 'draw edges' and 'draw creases' now exclude each other
2004-07-25 13:36:44 +00:00
e077328122 Added LSCM UV Unwrapping:
http://www.loria.fr/~levy/Galleries/LSCM/index.html
http://www.loria.fr/~levy/Papers/2002/s2002_lscm.pdf

Implementation Least Squares Conformal Maps parameterization, based on
chapter 2 of:
Bruno Levy, Sylvain Petitjean, Nicolas Ray, Jerome Maillot. Least Squares
Conformal Maps for Automatic Texture Atlas Generation. In Siggraph 2002,
July 2002.

Seams: Stored as a flag (ME_SEAM) in the new MEdge struct, these seams define
where a mesh will be cut when executing LSCM unwrapping. Seams can be marked
and cleared in Edit Mode. Ctrl+EKEY will pop up a menu allowing to Clear or Mark
the selected edges as seams.

Select Linked in Face Select Mode now only selects linked faces if no seams
separate them. So if seams are defined, this will now select the 'face group'
defined by the seams. Hotkey is still LKEY.

LSCM Unwrap: unwrap UV's by calculating a conformal mapping (preserving local
angles). Based on seams, the selected faces will be 'cut'. If multiple
'face groups' are selected, they will be unwrapped separately and packed in
the image rectangle in the UV Editor. Packing uses a simple and fast
algorithm, only designed to avoid having overlapping faces.

LSCM can be found in the Unwrap menu (UKEY), and the UV Calculation panel.

Pinning: UV's can be pinned in the UV Editor. When LSCM Unwrap is then
executed, these UV's will stay in place, allowing to tweak the solution.
PKEY and ALT+PKEY will respectively pin and unpin selected UV's.

Face Select Mode Drawing Changes:
- Draw Seams option to enable disable drawing of seams
- Draw Faces option to enable drawing of selected faces in transparent purple
- Draw Hidden Edges option to enable drawing of edges of hidden faces
- Draw Edges option to enable drawing of edges of visible faces

The colors for these seams, faces and edges are themeable.

f77bc7eb7d Quite a large one this time... but now we have:
Edges in Mesh
- adds automatic when you use creases. For other situations; call the
  void make_edges(Mesh *me) in mesh.c. Of course, once in editmode the
  edges are automatically recreated.
- in F9 buttons you can add/remove edges too
- both for Mesh and DisplistMesh, so it speeds up drawing quite some in
  wireframe
- render for edges can't work... edges have no material nor tface nor col..
  so here still the faces are rendered in wire

Creases in Subsurf
- based on the code by Chris McFarlen
- main changes is that now edges are used, saving quite some data in file
- use SHIFT+E in editmode to set edges-sharpness. values go from 0-1
- in F9 buttons you can set draw-crease mode. It draws now blended from
  wire color to edge-select color (as provided in Theme)

Known issue: setting sharpness on 1 cube (subdiv 2) gives weird results
with some values... Chris, can you check?

Further; code cleanups, changing 0 in NULL when needed, no warnings, etc etc
2004-07-08 20:38:27 +00:00
a8ef804146 NEW: Ramp shades for diffuse and specular
http://www.blender3d.org/cms/Ramp_Shaders.348.0.html

Material color and specular now can be defined by a Colorband. The actual
color then is defined during shading based on:
- shade value (like dotproduct)
- energy value (dot product plus light)
- normal
- result of all shading (useful for adding stuff in the end)

Special request from [A]ndy! :)

e750478ce3 The revised patch from Leon for new particle effects.
New is that objects can have a force field, and Meshes can even deflect
(collide) particles. This is in a new sub-menu in Object buttons F7

The full instructions where on the web, Leon mailed it me and I will put
it in CMS tomorrow. For those who like to play with it now, here are demo
files:

http://download.blender.org/demo/test/

Quite some changes where in the integration though... so previous created
particle deflectors will not work. Changes to mention now are:
- gravity is renamed to 'force field'
- force field and deflector options are in Object now, not in Mesh
- the options also have its own struct, doesnt add to Object by default
- force fields are possible for all object types, but only work on center.
  So empty objects are typical for it.

Work to do:
- add draw method in 3d win to denote forcefield objects
- check on the UI (panel with different size?)
- add 'recalc' button in deflector panel

c8fadc65dc Bug #1003
Using Nkey in 3d window, you could create a parent-loop, which hangs
Blender.
Added here that it checks loops, as for normal CTRL+P parenting.
2004-04-06 19:16:14 +00:00
7ba91ad2da New UV Calculation panel and code. The uv mapping function was split up into
multiple functions and partially recoded. Because now all the uv mapping
settings are accessible throught the panel, no popus will be shown when
pressing 'U' to unwrap faces in face select mode. Also From Window to Cylinder
and From Window to Shpere became obsolete, as you can set this in the new
panel.

The panel contains buttons for all the existing uv mapping modes, and the
following settings:

- Cube size: For Cubical unwrapping.

- Radius: Radius for Cylindrical unwrapping.

- View Aligns Face, View Aligns Top, Align to Object: For Cylinder and Shpere.
Respectively means you are in front of the Cylinder/Sphere, look through the
Cylinder, or use the object rotation to determine how the cylinder is
positioned (old Cylindrical unwrapping).

- Polar XZ, Polar XY: With 'View Aligns Top' enabled, defines at which polar
you are looking.

- No Edges, Draw Edges, All Edges: Draw no edges, draw edges z-buffered on top,
draw all edges, without depth test.

All credits for this part (and also at least half of the other UV editor
improvements) go to Jens Ole Wund aka "bjornmose".

3ce1dc9065 Area lights and more...
- New lamp type added "Area". This uses the radiosity formula (Stoke) to
  calculate the amount of energy which is received from a plane. Result
  is very nice local light, which nicely spreads out.
- Area lamps have a 'gamma' option to control the light spread
- Area lamp builtin sizes: square, rect, cube & box. Only first 2 are
  implemented. Set a type, and define area size
- Button area size won't affect the amount of energy. But scaling the lamp
  in 3d window will do. This is to cover the case when you scale an entire
  scene, the light then will remain identical
  If you just want to change area lamp size, use buttons when you dont want
  to make the scene too bright or too dark
- Since area lights realistically are sensitive for distance (quadratic), the
  effect it has is quickly too much, or too less. For this the "Dist" value
  in Lamp can be used. Set it at Dist=10 to have reasonable light on distance
  10 Blender units (assumed you didnt scale lamp object).
- I tried square sized specularity, but this looked totally weird. Not
  committed
- Plan is to extend area light with 3d dimensions, boxes and cubes.
- Note that area light is one-sided, towards negative Z. I need to design
  a nice drawing method for it.

Area Shadow

- Since there are a lot of variables associated with soft shadow, they now
  only are available for Area lights. Allowing spot & normal lamp to have
  soft shadow is possible though, but will require a reorganisation of the
  Lamp buttons. Is a point of research & feedback still.
- Apart from area size, you now can individually set amount of samples in
  X and Y direction (for area lamp type 'Rect'). For box type area lamp,
  this will become 3 dimensions
- Area shadows have four options:
  "Clip circle" : only uses a circular shape of samples, gives smoother
  results
  "Dither" : use a 2x2 dither mask
  "Jitter" : applys a pseudo-random offset to samples
  "Umbra" : extra emphasis on area that's fully in shadow.

Raytrace speedup

- improved filling in faces in Octree. Large faces occupied too many nodes
- added a coherence check; rays fired sequentially that begin and end in
  same octree nodes, and that don't intersect, are quickly rejected
- rendering shadow scenes benefits from this 20-40%. My statue test monkey
  file now renders in 19 seconds (was 30).

Plus:

- adjusted specular max to 511, and made sure Blinn spec has again this
  incredible small spec size
- for UI rounded theme: the color "button" displayed RGB color too dark
- fixed countall() function, to also include Subsurf totals
- removed setting the 'near' clipping for pressing dot-key numpad
- when you press the buttons-window icon for 'Shading Context' the context
  automaticilly switches as with F5 hotkey

Please be warned that this is not a release... settings in files might not
work as it did, nor guaranteed to work when we do a release. :)
2003-12-29 16:52:51 +00:00
97d4dbc9c3 Another commit for raytracing, now with glass refraction & fresnel!
Changelog:

- enable refraction with button "Ray Transp" in Material buttons.
- set "Angular Index" value for amount of refraction.
- use the "Alpha" value to define transparency.
- remember to set a higher "Depth" too... glass can bounce quite some
  more than expected.
- for correct refraction, 3D models MUST have normals pointing in the
  right direction (consistently pointing outside).
- refraction 'sees' the thickness of glass based on what you model. So
  make for realistic glass both sides of a surface.

- I needed to do some rewriting for correct mirroring/refraction,
  especially to prevent specularity being blended away.
  Solved this with localizing shading results in the rendercore.c.
  Now specularity correctly is added, and reduces the 'mirror' value.
- Localizing more parts of the render code is being planned. The old
  render heavily relies on struct Render and struct Osa to store globals.
  For scanline render no problem, but recursive raytracing dislikes that.

- done test with gamma-corrected summation of colors during tracing, is
  commented out still. But this will give more balanced reflections. Now
  dark reflections that are reflected in a bright surface seem incorrect.

- Introduced 'Fresnel' effect for Mirror and Transparency. This
  influences the amount of mirror/transparency based at viewing angle.
  Next to a new Fresnel slider, also a 'falloff' button has been added to
  define the way it spreads.
- Fresnel also works for Ztransp rendering

- created new Panel for Raytrace options
  I have to evaluate still where it all should be logically located.
- material preview shows fake reflection and fake refraction as well.
2003-12-16 14:12:01 +00:00

5bd910ae2c - added buttons for NKEY menu editmode curve, nurbs, armature
- same for PoseMode
2003-10-28 16:26:51 +00:00
a5247cf5b8 - fixed bug in wrong event code, causing some plugin buttons not working
- added redraw events to plugin buttons, to show updates better
2003-10-28 14:37:47 +00:00
4bec8ba7d5 Fixing loose ends:
- nkey menu for buttonswindow (hex values) couldnt be restored yet, is
  for next release
- replaced Nkey in IpoWindow with Panel, this now displays the buttons
  that were formerly in 'anim buttons' as well; to view the boundbox
  values of all visible curves, and adjust it.
- the new panel also has the 'set speed' option, fixed stuff in it and
  added better errorwarning... still not a very well coded tool!
2003-10-28 14:20:03 +00:00
0c177df766 - added Panel for 'anim playback settings'
- removed draw rect from avi coded settings (should become label but)
- changing texture settings, now also updates lamp/material/world
  preview when thats open
