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.

a51896b591 Move the settings in the Mesh Tools panel to the new toolsettings struct in Scene. These settings are now saved per scene. 2005-08-24 20:37:25 +00:00
dd5410162a New feature; User definable Clipping Planes.
Press ALT+B in 3d window, draw a rect, and it becomes a clipping
volume of 4 planes. You then can rotate the view anyway you like.
Works for each 3d window individually.

Disable it with another ALT+B press.

Commit is huge because it had to change all selection code as well.
The user-clipping planes are in 'eye space', the other clipping
happens in projected 'viewport space'.

Nice to notice is that the 'x=3200' convention (to denote a coordinate
is clipped) now is a define. Define value is still a number though... but
we now can get up to screens of 12000 pixels without issues!

Known issue; here it refuses to draw the 'object centers' or Lamp icons
within the clipping region. Can't find any reason for it... however, we
might move to non-pixmaps for it anyway.

Testing might reveil numerous issues, will be standby for it.

Curious? Check this http://www.blender.org/bf/rt4.jpg

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).

8a58197cf3 - change modifier applyModifier[EM] function to not free derived argument
- added modifier_supportsMapping function
 - update CCG to set actual vertex normal (and not just
   interior face vertex normal, bla bla bla no one knows
   what this means nevermind).
 - renamed modifierType_get_info to modifierType_getInfo for
   consistency and to increase my commit line count.
 - update EditMeshDerivedMesh to calculate (and use new) normals
   when given deformed vertices
 - added
 - update editmode modifier calculation to also calculate a cage,
   not working 100% atm, in particular if a deformer follows a modifier
   that returns a DerivedMesh the cage is not accurate.
 - added ccg derivedmesh drawMapped{Vert,Face]NormalsEM functions
 - currently UI for selecting the cage mesh is rather irritating,
   will be updated

410512e265 Patch provided by Shaul Kedem: Compressed files are back!
He even made a nice doc in wiki:
http://wiki.blender.org/bin/view.pl/Blenderdev/Blendgz

Usage: set the option "Compress File" in the main "File" pulldown menu.
This setting is a user-def, meaning it is not changed on reading files.
If you want it default, save it with CTRL+U.

The longest debate went over the file naming convention. Shaul started
with .blend.gz files, which gave issues in Blender because of the code
hanging out everywhere that detects blender files, and that appends the
.blend extension if needed.

Daniel Dunbar proposed to just save it as .blend, and not bother users
with such details. This is indeed the most elegant solution, with as
only drawback that old Blender executables cannot read it.
This drawback isn't very relevant at the moment, since we're heading
towards a release that isn't upward compatible anyway... the recode
going on on Meshes, Modfiers, Armatures, Poses, Actions, NLA already
have upward compatibility issues.
We might check - during the next month(s) - on a builtin system to
warn users in the future when we change things that make a file risky
to read in an older release.

951a4934b0 - added wave modifier & removed old wave effect
- added decimate modifier & removed old decimate interface
   (currently lacks warning about destroying data, and there needs
   to be a way for modifiers to return errors back to the interface)
 - allow applyModifier to return NULL to indicate error
 - unfortunately new decimate modifier means it does not know exact
   number of faces in mesh (other modifiers may come before) and so
   instead interface uses a percentage. if people need exact face
   count slider then I will have to think of some hack to fit this
   in. note that it does display the output face count so its possible
   to tweak the pct to get what you want regardless.
 - removed python Wave object

If you are bored now how much easier it is to implement something
like decimate as a modifier. Very few changes to interface, very
few entry points.

259c7b6cad - added modifier_dependsOnTime to check if modifier needs updating
based on time change. would be nice if dep graph could handle this.
 - made dep check if modifiers need update on time change
 - fix render crash (access null)
 - added new Build Effect modifier type. compared to old one works as
   a full member of modifier system, means can apply subsurf, etc on
   it, reorder, what have you. and it is all nice and self contained.
 - removed old Build effect, old files convert to new style on load
 - couldn't help myself, added a randomize feature to build effect
 - removed Python BuildEffect support
2005-07-20 04:14:21 +00:00
1df154d140 - split {curve,lattice,armature}_deform_verts out of mesh_deform
- removed mesh_deform (merge into mesh_modifier)
 - switch python lattice_apply function to use object_apply_deform,
   this isn't exactly equivalent but the python system shouldn't
   have been calling that deep into the kernel anyway.

New feature: Modifier stack
 - added Object.modifiers (list of ModifierData elements)
 - added DNA_modifier_types.h
     o contains type definition for the file data for the various
       modifier types
 - added BKE_modifier.h
     o contains modifierType_get_info (access to modifier type registry)
     o structs and defines for runtime modifier usage
 - updated mesh_calc_modifiers to evaluate modifier stack (note that
   for the time being it also evaluates the old style modifiers so files
   should load and work as normal).
 - add file handling modifier code (todo: don't replicate on object copy)
 - add modifier stack UI code (lives in object panel)


Only real new feature at the moment is that you can apply lattices and
curves *after* a subdivision surface which was never possible before.

Todo:
 - DEP graph updating does not work correctly yet, so you generally have
   to tab cycle to see results.
 - editmode calculation does not use modifier stack.
 - bug fixes (there must be a few in there somewhere)
2005-07-19 20:14:17 +00:00
c8f195d00c - Fix for action constraints; for Bone targets (target is input bone
actually) only the relative rotation is used.

- Added scale=1.0 initializer in saving files, this fixes a little  bit
  better upward compatibility

- Still there are cases where bones flip 180 degrees when you read it with
  older Blenders... not sure what it is caused by

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!

09fb5d6b8d BPython:
- Made Blender.event var (previously only used by script links) hold ascii value -- where it applies -- of current event during events callback registered with Draw.Register(gui, events, button_events).  Useful for gui scripts like Campbell's Python console. No problem using this var to hold the value, since in gui scripts it was not used (always None).

- Updated Window and Window.Theme with new theme vars and the Time space.

- Script links:

-- Added "Render" event for script links (runs twice, second time as "PostEvent", for clean-up actions). Now FrameChanged links don't run when a single pic is rendered.

-- Added "Enable Script Links" button in the script buttons tab.  Now this bit gets saved in .blends along with the rest of G.f, so users can define per .blend if they are on or off by default.  "blender -y" also disables all slinks as happened before with OnLoad ones only.

-- Other small changes in the script buttons tab:
  When a link is added (button "new"), it becomes the active one for the window, no need to press a button to reach it.
  Also, a pupmenu showing all available texts is shown when "new" is pressed, so users can choose a text w/o having to type.  Cancel the popup to leave the string button empty (link exists, but has no script assigned).  A pulldown would be better UI-wise, but it's kinda weird to show both scripts and normal texts (Blender doesn't differentiate them) in a script links pulldown.  With a popup we can show only texts ending in ".py" (not done in this commit, need opinions) and if the script has no or another extension, case of many in old and current .blend's, there's still the string box for writing its name.

-- Implemented Ton's space handler script links:

Right now only for the 3d View,  but it's trivial to add for others.  There are two types: EVENT, to receive 3d View events from a chosen window and DRAW, to draw on the window.  Ton's idea was to give scripts a controlled way to integrate better within Blender.

Here's how it works:

- scripts must have a proper header, like:
# SPACEHANDLER.VIEW3D.EVENT

and then they are shown in 3d View's View menu, "Space Handler Scripts" submenu.  Check (mark, click on it) a script to make it active.

EVENT handlers should consult the Blender.event var to get the current event, which can be compared with values from the Draw module:

import Blender
from Blender import Draw

evt = Blender.event
if evt == Draw.AKEY:
  print "a"
elif evt == Draw.LEFTMOUSE:
  print "left mouse button"
else:
  return # ignore, pass event back to Blender

Blender.event = None # tell Blender not to process itself the event

DRAW handlers are free to draw to their owner 3D View. OpenGL attributes and modelview and projection matrices are pushed before running the handler and poped when it finishes.

To communicate between EVENT and DRAW handler scripts we have the Blender.Registry module, as always.

Still need to code some nice example, which should also serve to test properly space handlers.  Simple tests went fine.

- doc updates about the additions.

=======

Note: the UI part of the space handlers and script links is of course open for changes, I just tried to make it understandable.  Probably we won't use the scriptlinks icon for "None Available" (check 3d View -> View -> Space Handler Scripts), though it hints at what space handlers are.  The tooltips may not be accepted either, since other menus don't use them.  Opinions welcomed.

f0a4ce98f9 Added the new Timeline Window, copied from Tuhopuu, coded by Matt Ebb.
Main change is that it's an own Space type now, not part of the Audio
window... the audio window should restrict to own options. This way
functionality is nicely separated.

Since it's the first time I added a new space (since long!) I've made an
extensive tutorial as well. You can find that here:
http://www.blender3d.org/cms/Adding_new_Space_Window.557.0.html

Notes for using timewindow;

- Add time markers with MKey
- CTRL+M gives option to name Marker
- Markers cannot be moved yet...
- Pageup-Pagedown keys moves current frame to next-prev Marker
- Xkey removes Markers

- If an object has Ipos or an Action, it draws key lines
- CTRL+Pageup-Pagedown moves current frame to next-prev Key

- Press S or E to set start/end frame for playback

Notes about the implementation in Tuhopuu:

- Add new Marker now selects new, deselects others
- Selecting Marker didn't work like elsewhere in Blender, on click it
  should deselect all, except the indicated Marker. Not when holding SHIFT
  of course
- Not exported functions are static now
- Removed unused defines (MARKER_NONE NEXT_AVAIL)
- Drawing order was confusing, doing too many matrix calls
- Removed not needed scrollbar, added new function to draw time values.
  (Has advantage the MMB scroll works not confusing on a scrollbar)
- Added proper support for 'frame mapping'
- The string button (name Marker) had a bug (checked str[64] while str
  was only 64 long)
- String button itself didn't allow "OK on enter"
- Made frame buttons in header larger, the arrows overlapped
- Removed support for negative frame values, that won't work so simple!
2005-05-05 17:19:21 +00:00
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.
2005-05-02 13:28:13 +00:00
bdb86d7c67 Integration stage of Softbody project
User level notes are in Wiki here;
http://wiki.blender.org/bin/view.pl/Blenderdev/Softbodies
And will be added in blender3d.org CMS later.

Tech level notes are still pending, but here's the most relevant ones;

- made ob->soft struct SoftBody to hold all settings, and read/save in
  files
- added (temporal!) conversion for the old settings. So: read old files
  with softbody experiments now, and save over!
- cleaned API calls for softbody, which are only 5 of them now:
  sbNew()
  sbFree()
  sbObjectStep()          (animation steps)
  sbObjectToSoftbody()    (full re-initialize data)
  sbObjectReset()         (only reset motion)
- API calls accepts time in frames now, within softbody.c it converts

Further, internally code was cleaned some (missing tabs etc). Also tried
to keep a well defined structure with hints how to add support for more
objects. Can write notes about that...

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!

aad31875d7 Special bf-committers request; Lamp/World/Material now each have 10
channels to link texture to.

The amount of code changes seems large, but is mostly getting rind of
hardcoded values (6 and 8) for channels, replacing it with MAX_MTEX.

Further did some fixes;
- Ipo for Lamp showed too many mapping channels
- Texture MapTo buttons for lamp missed the slider to blend texture color
- Lamp texture mapping "View" only worked for Spot, now it uses lamp-
  view vector for all types. (Nice for projections!)

9393dd08af Fixed showstopper (thnx intrr!) bug in sequencer + global undo.
This was actually a wrong pointer check in fileread that caused no harm
in past, but with UI-less file save it wreaked havoc!

Decided to add undo in sequencer window after all... it also involved
saving Meta strip settings in files. Very nice :)

b63f41a518 Fix for bug #1562
There's an ancient code in Blender to denote a projected vertex coordinate
is invisble, it sets the x coord at 3200. :)
This wasn't updated while coding loopselect, nor edge select. Causing in
extreme zoomed in situations vertex selecting go wrong.

Also added; option "don't load GUI" in fileselector doesn't get saved in
files.
2004-10-13 09:17:10 +00:00
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...

a2e918d831 EditMesh refactory + undo recode
The changelog is very long... it's on the web too:
http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html

EditMesh refactor notes (user)

**** New selection modes

When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!).

- Vertex Select
Select vertices as usual, fully compatible with how previous version work

- Edge Select
Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected.

- Face Select
Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges.

While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected.
For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too.

The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well.
Most noticeable it's in:

**** Extrude

Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it.

New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual.

**** Other things to note

- Hiding edges/faces will also behave different based on Select Mode.
- while editing, normals of faces are updated always now
- Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border.
- in face mode, adding vertices, edges or a circle is invisible...
- "Add monkey" now works as a normal primitive (rotated and on 3d cursor)
- Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups
- Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain.

**** Todo

Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture.

**** Usage of flags in general
The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now.
The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them.

**** Selection flags
EditVert: eve->f & SELECT
EditEdge: eed->f & SELECT
EditFace: efa->f & SELECT

- Selection is only possible when not-hidden!
- Selection flags are always up-to-date, BUT:
  if selection mode >= SELECT_EDGE vertex selection flags can be incorrect
  if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect
  This because of shared vertices or edges.

- use for selecting vertices:
  eve->f &= SELECT
- use for selecting edges always:
  void EM_select_edge(eed, 1)  // 1 = select, 0 = deselect
- use for selecting faces always:
  void EM_select_face(efa, 1)  // 1 = select, 0 = deselect

- To set the 'f' flags in all of the data:
  void EM_set_flag_all(int flag);
  void EM_clear_flag_all(int flag);

- the old faceselectedOR() and faceselectedAND() are still there, but only
  to be used for evaluating its vertices

**** Code hints for handling selection

If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore.

However, by using the above calls, at least selections flush downward (to vertex level). You then can call:

void EM_selectmode_flush(void);

Which flushes selections back upward, based on the selectmode setting. This function does the following:

- if selectmode 'vertex': select edges/faces based on its selected vertices
- if selectmode 'edge': select faces based its selected edges

This works fine in nice controlled situations.

However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call:

void EM_select_flush(void);

Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives.


**** Hide flags
EditVert: eve->h
EditEdge: eed->h
EditFace: efa->h

- all hide flags are always up-to-date
- hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag.

**** Unified undo for editmode

New file: editmode_undo.h
A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference.

Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions.

**** Going in/out editmode

As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed.

ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

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.

ae9347662b Stretch To constraint
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).
2004-09-05 20:21:16 +00:00
bf83f6ddd8 Second itteration of global undo system. Now based on:
- file-to-memory save
- incremental difference steps (compression)

everthing has been tightly coded to use minimum of memcpy or allocs. In
fact this system works with a single full buffer (=file) in memory, and undosteps as differences from it.
Speed gain is factor 4-8 faster. I've added it in CTRL+ALT+T timer menu for
a test. Please note the gain is especially in the undo-storing, not in
retrieving undo.

Also new: file read option to skip UI read (file menu). This now also is
default for the undo system.

248404e7a2 This commit changes the sweep effect to be called 'Wipe' in both UI and in backend variable naming. 2004-08-03 19:36:17 +00:00
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

8a0cd0bc97 Added another Sequence effect: the wellknown Glow effect. 2004-06-23 22:11:57 +00:00
629e526b25 - Added correct Writing/Reading of the new Sweep sequence effect (Thanks Ton, where would I be without you)
- Sweep effect updates after you change the type of sweep now.
2004-06-23 18:22:51 +00:00
255cd235a3 - Returned multi-user support on Win2k/XP.
Now uses 'Application Data/Blender Foundation/Blender' instead of old
  "Not A Number" dir.

- Updated windows installer to make this change transparent for the
  users. It copies /.blender to the new location and displays a short
  message to advise them of the change
  (http://homepages.nildram.co.uk/~aphex/installer_msg.jpg).

- Installer also includes fix for opening blend files from explorer (patch provided by Valentin Ungureanu (vung) - thanks!)

Note to CVS users on Win2k/XP:  Although blender will continue to work
without changes, you should ideally copy the /.blender dir to
<app data>/Blender Foundation/Blender for the sake of correctness :)

39a8c014c4 This commit removes the glue from Blender, and with it
the directories decrypt, deflate, encrypt, inflate, readstreamglue,
sign, writeblenfile and writestreamglue.

Sirdude was so kind to modify the makefiles, so SCons and
Make are ready to build with the new Blender.

Visual Studio workspaces, solutions and projectfiles still need
to be updated (I'll do the .vcprojs and .sln myself after this commit).

Runtimes created with the Blender Publisher are not anymore
recognised - if you want these available, you'll have to convert
them first to .blends with the Publisher.

aedf456938 - split the data structures that actually constitute a mesh
(MVert,MFace,etc) off into DNA_meshdata_types.h, to isolate areas
    of source that actually edit mesh *data* vs. areas that just edit
    mesh object information.

6d68c41e62 last minute commit -- saving .b.blend files on Windows for users
who have set a %HOME% environment var now works again.
Patch provided by Bill Baxter, plus an additional fix for Win9x.

There is still work to be done with this after the 2.32 release...

1126706d2e - [win32] now really using the directory Blender is installed in. My patch was kinda incomplete, but aphex_ (Simon) was kind enough to point out the lines to edit :) 2004-01-07 21:03:11 +00:00
49021f7ec4 BPython - first step for better integration of Python in Blender:
- add a new space: Space Script
- add a new dna struct: Script
- add these two properly everywhere they are meant to

It's not a tiny commit, but most of it is ground work for what is still to be done.
Right now the benefits should be: freeing the Text Editor to be used in a window even while a script w/ gui in "on" and letting more than one currently running script w/ gui be accessible from each window

Some files are added, so some build systems (not autotools) will need updates

066df297b5 - fixed a bug when saving user defaults (Win32 only)
(the first save didn't store paths or font settings!)

This is something I broke back at 2.28a :)
I'm suprised there were no bug reports on this, but it's fixed now! ;)

4efdabfbbc Constraint stuff from tuhopuu including (but probably not limited too):
Axis options for TrackTo
LockTrack
FollowPath

Auto creation of TrackTo constraint from Ctrl-T (old track still an option)

Auto creation of FollowPath when parenting to path (Normal parent still an option)

Backward compatibility stuff to convert the per object axis settings to per constraint when a Track constraint is present.

Function to convert old track to constraint (commented out)

Revamped the constraints interface with Matt's work from tuhopuu and the stuff we were discussing earlier.

--------------------
For coders:

unique_constraint_name and *new_constraint_data  moved to the kernel (constraint.c)

new Projf function in arithb gives the projection of a vector on another vector

add_new_constraint now takes a constraint type (int) parameter

add_constraint_to_object(bConstraint *con, Object *ob) to link a constraint to an object

add_constraint_to_client(bConstraint *con) to link constraint to current client (object or bone)

add_influence_key_to_constraint (bConstraint *con) to (eventually) add a keyframe to the influence IPO of a constraint

0321602b65 - The basic layer for Themes in place!
- currently only implemented for 3d window
- create as many themes you like, and name them
- default theme is not editable, and always will be defined at startup
  (initTheme)
- saves in .B.blend
- themes for spaces can become local too, so you can set individual
  3d windows at theme 'Maya' or so. (to be implemented)
- it uses alpha as well...!

API:
This doesnt use the old method with BFCOLORID blahblah. The API is copied
from OpenGL conventions (naming) as much as possible:

- void BIF_ThemeColor(ScrArea *sa, int colorid)
  sets a color... id's are in BIF_resources.h (TH_GRID, TH_WIRE, etc)

- void BIF_ThemeColorShade(ScrArea *sa, int colorid, int offset)
  sets a color with offset, no more weird COLORSHADE_LGREY stuff

- void BIF_GetThemeColor3fv(ScrArea *sa, int colorid, float *col)
  like opengl, this gives you in *col the three rgb values

- void BIF_GetThemeColor4ubv(ScrArea *sa, int colorid, char *col)
  or the one to get 4 bytes

ThemeColor calls for globals (UI etc) can also call NULL for *sa... this
is to be implemented still.

Next step: cleaning up interface.c for all weird colorcalls.

842bb449c5 huge commit, sorry!
this is part 1 of the UI makeover. It has:
- menu system from Matt integrated
- buttons drawing from Matt
- generic button panel system implemented
- converted displaybuttons (not the rest yet)
- cleaned up a lot in drawing spaces itself, to make it aligned and pixel exact.
- cleaned loads of little compiler warnings, protos...

still a lot of work needed, will all be in next week i hope!

(warn: 2 new c files! butspace.c and buttons_scene.c)
2003-10-04 20:35:50 +00:00
aa9f2a5733 - saves the 'draw faces' flag in a file, in fact the entire G.f flag.
WARN: this recompiles other stuff too, outside of the loader. be sure
  to 'make' in source/blender/ or a higher dir.

4f27386740 Commit message and the brunt of the code courtesy of intrr, apologies for the
size of this;


Finally, the Sequencer audio support and global audio/animation sync stuff!
(See http://intrr.org/blender/audiosequencer.html)

Stuff that has been done:

./source/blender/blenloader/intern/writefile.c
./source/blender/blenloader/intern/readfile.c

Added code to make it handle sounds used by audio strips, and to convert
Scene data from older (<2.28) versions to init Scene global audio settings
(Scene->audio) to defaults.

./source/blender/include/BSE_seqaudio.h
./source/blender/src/seqaudio.c

The main audio routines that start/stop/scrub the audio stream at
a certain frame position, provide the frame reference for the current
stream position, mix the audio, convert the audio, mixdown the audio
into a file.

./source/blender/makesdna/DNA_sound_types.h

Introduced new variables in the bSound struct to accomodate the sample
data after converted to the scene's global mixing format (stream, streamlen).
Also added a new flag SOUND_FLAGS_SEQUENCE that gets set if the Sound
belongs to a sequence strip.

./source/blender/makesdna/DNA_scene_types.h

Added AudioData struct, which holds scene-global audio settings.

./source/blender/makesdna/DNA_sequence_types.h

Added support for audio strips. Some variables to hold Panning/Attenuation
information, position information, reference to the sample, and some flags.

./source/blender/makesdna/DNA_userdef_types.h
./source/blender/src/usiblender.c

Added a "Mixing buffer size" userpref. Made the versions stuff initialize
it to a default for versions <2.28.

./source/blender/makesdna/DNA_space_types.h
./source/blender/src/filesel.c

Added a Cyan dot to .WAV files. Any other suggestions on a better color? :)

./source/blender/src/editsound.c

Changes (fixes) to the WAV file loader, re-enabled some gameengine code that
is needed for dealing with bSounds and bSamples.

./source/blender/src/editipo.c
./source/blender/src/drawseq.c
./source/blender/src/editnla.c
./source/blender/src/space.c
./source/blender/src/drawview.c
./source/blender/src/renderwin.c
./source/blender/src/headerbuttons.c

 - Created two different wrappers for update_for_newframe(), one which scrubs
   the audio, one which doesn't.
 - Replaced some of the occurences of update_for_newframe() with
   update_for_newframe_muted(), which doesn't scrub the audio.
 - In drawview.c: Changed the synchronization scheme to get the current audio
   position from the audio engine, and use that as a reference for setting
   CFRA. Implements a/v sync and framedrop.
 - In editipo.c: Changed handling of Fac IPOs to be usable for audio strips as
   volume envelopes.
 - In space.c: Added the mixing buffer size Userpref, enabled audio scrubbing
   (update_for_newframe()) for moving the sequence editor framebar.

./source/blender/src/editseq.c

Added support for audio strips and a default directory for WAV files which
gets saved from the last Shift-A operation.

./source/blender/src/buttons.c

Added Scene-global audio sequencer settings in Sound buttons.

./source/blender/src/sequence.c

Various stuff that deals with handling audio strips differently than
usual strips.
