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!

422b69fe1e UI cleanup work;
Proportional edit:

- Proportional mode added to header as button/menu. Including new option
  to have only connected geometry influenced.
- Added icons for proportional & proportional modes
- Make proportional edit data part of Scene, so all gets saved.
  The Global flag G_PROPORTIONAL was removed
- Made sure #defines get used properly, also tweaked order for proportional
  so it starts with regular 'smooth' by default.
- Use ALT+O in editmode to switch to new proportional 'connected' mode

Other UI stuff:

- in EditMode, the layer buttons get hidden... the amount of icons in
  3d header grows to fast. :)
- made less ugly icons for the Manipulators. Still can be better.
- Added alpha-filter for pre-processing Icon-image, giving nicer display
  of icon-antialising on dark or bright backdrops
- disabled Manipulators when in editmode, and current layers don't show
  the edited data.
- Added the value used to define Normal size (editmode draw) in Scene too,
  so it gets saved.
2005-05-03 10:54:42 +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.

79e333343b Dependency graph patch, provided by Jean-Luc Peuriere.
Works like a charm... well it now replaces the old base-sorting hack. :)
Next stage will be to define how to further integrate it. Plus some
minor code cleanups... static/internal functions versus external, etc.
2005-04-30 21:27:05 +00:00
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. :)
2005-04-23 20:49:23 +00:00
375cf60462 Commented out DOF code that did not have a home yet because it broke
compile. Normally it would probably be best just to wait till Ton committed
but its still pretty early and I didn't want people complaining all night.
Hope its no problem!

075ed5fd53 The do_versions() for new shaders always initialized the values... 2005-04-22 21:31:52 +00:00
be3eec3014 Softbody: added "time" button, to control speed for wriggling. Low values
make it slower, higher values faster.

Monkey: accidentally got inverted normals for they eye again. :)
2005-04-20 16:55:04 +00:00
425f295604 Patch submitted by Jorge Bernal (lordloki) and Jonathan Merritt.
This will add Minneart diffuse and WardIso specular to our shader menu.
Minneart gives nice control over darkness/brightness areas, the wardIso
over 'plastic' style sharp or fuzzy specular.

Webpage is being made with nice samples. Will be in release log.

Jorge: one change is in the do_versions, you inserted it on wrong location.
2005-04-17 17:43:07 +00:00
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
24c9f65056 - got tired of str[n]casecmp not declared warnings
- added BLI_str[n]casecmp, use instead of regular versions
 - rewrote BLI_str[n]casecmp to not be stupid
2005-04-02 15:36:57 +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...

340748fd5c - zero derivedmesh pointers on load 2005-03-29 17:52:14 +00:00
c3abdd9608 Cleanup of widget code;
- made more general calls with args for drawing types
- made it accept transparency for all modes (used while transform now)
- added argument to detect 'combo' mode, gave offsets to translate/scale
  handles in combos.
- added 'pie chart' on view-aligned rotate for widget
- made trackball for rotate widget rt==4 behave compatible
- removed redundant code for 'ghosting'
2005-03-28 14:00:49 +00:00
a2ed880c9f Transform widgets; Scale and Rotate versions
To use; press the (temporal) icon in header. Switching widget types is by
pressing G, R or S once, if current widget type is different it switches,
otherwise it goes to normal Transform().

Widgets need a bit test for picking accuracy, correct drawing etc.
The rotate widget has a center button for 'trackball' rotate. That latter
can also be used for hotkey-based rotate.

In current code, all widgets remain in "Global" space, also in editmode.
Also widget updates while using normal transform has to be done.

2 Bugfixes:
- rotate in PoseMode had error for 2d 'around' center
- transform in postemode could crash, due to typo (& or |)

fa2a1c84c7 Bug fixes;
#2187: Append to active layer now uses the real active layer
#2191: Stars didnt show up correctly in envmap render
#2194: Startfame > Endframe in anim render crashed (now it gives error)

996374bb5a Fixed old annoyance; enabling true Ortho render in Blender.
It used to be a simple hack, scaling lens with 100, and moving the camera
to the back with an equivalent amount.
Because of the hack, making it 100% compatible with older files I could not
achieve (yet?). To help reminding users, I've added a print when reading
old files with Ortho cameras.

Full description of how it works can be found here;

3e38a951dd Bug fix #2104
When using Sequencer for Alpha-Over images, it was assuming "Key" alpha by
default, and converting images to "Premul" (= multiplying RGB with alpha).
This isn't very nice, also because alpha generated by MBlur in Blender
always is of type Premul already.

Solution; make this an option. In the Nkey panel for strips you can set
or disable Premul now. As extra also added the "Filter" and "Mul" options,
as already there for Movie strips. Can easily be extended to more options
for various postprocess effects.

776b2451e1 Bugfix #2095
When loading a file with linked external scene, and that external scene
didnt exist anymore, and that scene was active in the file -> crash!

Render code; changed to use local 'puno' flag for threaded render.
2005-01-05 10:31:27 +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!

3bcc45ff64 Bug fix #1994
Sequence editor crash when you delete Scenes which were used as a strip.
Related to that, file reading code didn't restore pointers for strips
correctly when you save with open "Meta" strip.
First bug 8 year old. Second 1 month. :)
2004-12-10 14:50:39 +00:00
d8797f36f7 Bug fix based on bug report Chris Burt, IRC.
Appending objects with constraints expands links to objects (according
code) but doesn't give such objects a link to Scene.

Apprently, somewhere in NaN days, someone commented a call, which
already invoked comments... here's the full code + comments now:

	/* give a base to loose objects */
	give_base_to_objects(G.scene, &(G.main->object));
	/* has been removed... erm, why? (ton) */
	/* 20040907: looks like they are give base already in append_named_part(); -Nathan L */
	/* 20041208: put back. It only linked direct, not indirect objects (ton) */

:-)
2004-12-08 19:08:37 +00:00
ef4ac2b592 Narrowed code for restoring UI after undo. It seems still an error in
oops code, having pointers to ID structs that are invalid.

This solves at least it crashing... oops needs to be refreshed once :)

(occurred on testing complex files, with conversion from nurbs=>mesh)
2004-12-08 18:36:48 +00:00
d0cdf2bd4b More tweaks related to bump mapping quality;
While going over the code, I found out the "nabla", the size of offset
vectors for calculating derivatives of a texture, is a built in constant.
Even worse, the value was different for new noise types (musgrave etc).
So I've added a new slider for it in the procedural texture panels, which
by default is set to 0.025, the value of the old constant. Also made sure
it works with equal effect in all procedurals.

NOTE: a small Nabla will give sharper, detailed bump, but the effect also
becomes smaller, correct that in the Mapping Panel of materials.

For better & compliant control over the bumpmapping, I've also included
the Colorband output in derivatives calculus, so the bump output then
matches the color created. It's also a nice tool to finetune output of
textures for bumpmapping in general.

Bug fix; clicking on the rightmose 'item' in ColorBand didn't activate it.
Found out the ColorBand was slightly drawn off (2 pixels).
2004-12-07 14:46:48 +00:00
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!)
2004-12-04 21:49:02 +00:00
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...
2004-12-01 12:39:14 +00:00
7d7acbf6bd Bug #1865
On appending in posemoding, Blender could crash.
Found out the new 'select appended' also sets the 'active base/object'.
This isn't OK on that level of the code, 'active' exists (and needs to be
set) on UI code level in src/, not in the middle of file reading function.

Also removed weird negative bitflag that enforced 'select appended' to
be default. If you want that, set the flag itself in do_versions or so.
In my opinion it is best saved in .B.blend instead. Another time...
2004-11-21 13:25:54 +00:00
f2aa00d2d0 Bug fix #1859
Appending or Linking data from other file always cleared scene scriptlinks,
due to having 1 line of code just on wrong location... is bug since 2.25,
so finally something again I didn't recently break in working code :)
2004-11-21 11:44:50 +00:00
cefd1b2729 Three bugfixes from tracker;
- Nurbs objects didnt render ray-transp. Was caused by 1) wrong normal calc
  and 2) quads with vertices on same locations. Solved it with nice code that
  checks illegal quads and turns them into triangles
- Made 'physics engine' variable SUMO default
- Typo in toolbox fix; cyclic isn't F but C
2004-11-17 17:15:36 +00:00
0444ae2216 Localview fix of 2 hours ago created dependency with bad level calls...
removed calling function from src/ and added the few lines in readfile.c
2004-11-14 16:06:24 +00:00
847ff75b35 Bugfix in undo:
localview got stuck after an Undo command, it now restores to normal view
when no localviewed objects are there.

Please note again; localview is UI, so actually not saved in the undo...
2004-11-14 12:56:56 +00:00
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 :)
2004-11-13 12:55:59 +00:00
e9017926c9 Three minor fixes;
- themecolor for the 'bars' in NLA used signed char
- global undo, restore pointers for UI accidentally added user values for
  oops and outliner, causing unused blocks to show used
- moved popup menus one pix up or down, it was overlapping the button
  causing accidental selection of menus
2004-11-05 17:18:17 +00:00
cae8b8783d - Added initialize to '4' for new tab variable in text window
(prevents crash reported by sgefant!)
- Selection outline for Curve objects didnt draw right after leave
  editmode
- outliner now default when first viewing Oops window (dangerous?)
- Zoom with ctrl+middlemouse works in Oops again
2004-11-01 20:50:42 +00:00
1a49bf0c37 Bug #1721
Crash reported on combo of append object, do global undo, and re-append
same object. Appears to be an open filehandle...
2004-10-31 20:18:14 +00:00
63d81be035 Fix for #1706 (Wavk again!)
- Undo in texteditor didnt work, event (ALT+U) was swallowed by new undo
  menu (ALT+U too)
- global undo doesnt restore UI's as we know... so undo-ing with a text
  editor active cannot always restore correct text block you were editing.
  As extra service I added that when no restore is possible, it links to
  the first block available.
2004-10-29 15:00:11 +00:00
1a591506c6 When you save a file while using radio tool, it didn't load correctly
because of a flag set which prevented drawing the objects.
2004-10-18 22:39:14 +00:00
627a296ac6 Fix for #1569
Problem was dynamic linking of files with game logic. The links between
sensors/controllers/actuators got lost.
Never though i'd still understand the code, not too bad at all! :)
2004-10-13 17:59:44 +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...
2004-10-06 18:55:00 +00:00
04f5baee3a OK. Here's the long awaited first step (V0.01!) of SoftBody. It is called
from within mesh_modifiers (kernel deform.c). It copies vertices to a
temporal particle system (struct SoftBody with BodyPoint structs) to do
physics tricks with it.

For each frame change the delta movements (based on standard ipo anim or
even other deforms (later) are applied to the physics system. How to apply
and calculate satisfying results is not my thing... so here I'll commu-
nicate with others for.

Since it's in the modifier stack, the SoftBody code can run entirely on
original data (no displists!).

Right now I've implemented 2 things;

- "Goal" which is a per vertex value for how much the current position
  should take into account (goal=1 is without physics). This is a powerful
  method for artists to get control over what moves and not. Right now i
  read the vertex color for it.
- And some spring stuff, which now only works based on force moving it to
  the originial location. This doesnt work with 'goal'... erhm.

- You can re-use physics vars from engine, used right now is (in Object)
  - damping
  - springf (spring factor)
  - softflag (to set types, or activate softbody for it

- The SoftBody pointer in struct Object is only runtime, nothing saved in
  file

To prevent all users going to complain it doesn't work, I've hidden the
functionality. :)
The buttons to set softbody 'on' only show now (psst psst) when the object has
name "soft" as first 4 characters. You can find the buttons in the F7 Particle
Interaction Panel (which should be renamed 'physics properties' later or so.

30ef2326b9 - Made the 'zbuf clip select' in editmode default when reading on old file
- Added transparent wires in solid draw for editmmode, to denote selecting
  clicks "through". Switching this and the zbuf-clip mode is actually nice!

- little annoyance; removed object centerpoint drawing in editmode.

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.


EditMesh refactor notes (coder)

**** 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.

34aa59c5c3 - redo now also ctrl+y.
- made undo/redo display of previewrender nice
2004-09-18 18:34:50 +00:00
562d6958cb Another step in the undo evolution.
- Made unified API for undo calls, to be found in space.c
  BIF_undo_push(char *str)
  BIF_undo(void)
  BIF_redo(void)
  These calls will do all undo levels, including editmode and vpaint.

  The transition is work in progress, because mesh undo needs recode.

- New global hotkey CTR+Z for undo
  Note: 'shaded draw mode' still is SHIFT+Z, the old CTRL+Z was to recalc
  the lighting in shaded mode, which already became much more interactive,
  like during/after any transform().
  Recalc hotkey now is SHIFT+ALT+Z

  CTRL+<any modifier>+Z is redo.

- For OSX users; the Apple-key ("Command") now maps to CTRL as well. This
  disables the one-mouse-button hack for rightmouse btw, will be fixed in
  next commit. At least we can use Apple-Z :)

- Old Ukey for undo is still there, as a training period... my preference is
  to restore Ukey to "reload original data" as in past, and only use new
  CTRL+Z for undo.

- Added undo_push() for all of editobject.c and editview.c. Meaning we can
  start using/testing global undo in the 3d window. Please dont comment on
  missing parts for now, first I want someone to volunteer to tackle all of
  that.

- Since the global undo has a full 'file' in memory, it can save extremely
  fast on exit to <temp dir>/quit.blend. That's default now when global undo
  is enabled. It prints "Saved session recovery to ..." in console then.

- In file menu, a new option is added "Recover Last Session". Note that this
  reads the undo-save, which is without UI.

- With such nice new features we then can also kill the disputed
  Cancel/Confirm menu on Q-KEY.

- Added fix which initializes seam/normal theme color on saved themes.
  They showed black now.... (Note: that's in usiblender.c!)

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.

Nathan Letwory
538e11a45d Add two new options for appending *objects*:
1) append in current active layer (off by default)
2) append at 3d cursor (off by default). When more than one object is selected this will first calculate the bounding box of the centers of the objects, and then use the distance of the bounding box center to the 3d cursor to transform all objects.

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).
