Integration is still very rough around the edges and WIP, but it works, and can render smoke (using new Smoke format in Voxel Data texture) --> http://vimeo.com/6030983
More to come, but this makes things much easier to work on for me :)
Various fixes for painting, sculpting and particle edit, still
much to be done...
* Move RNA paint and sculpt structs into rna_sculpt_paint.c,
* Added Particle Edit RNA.
* Some tweaks to existing Paint RNA.
* Put texture paint and particle edit object in context.
* Fix some errors in the brush layout, properly doing None
checks, fixing some wrong property identifiers.
* Added tool enum for texture paint and particle edit in panels.
* Allow editing brush textures in the texture buttons, still with
a stupid toggle, ideas for how to make the connection better are
welcome.
* Windows fixes for texture filter & bump patches, thanks
Jean-Michel Soler for noting.
* Added sqrtf/sinf/fabsf/... fallback #ifdefs in BLI_arithb.h,
those should be safe to use now. Replacing the double for the
float version throughout the code can be done once, but would
need proper testing.
- 1st stage: Linear Workflow
This implements automatic linear workflow in Blender's renderer. With the
new Colour Management option on in the Render buttons, all inputs to the
renderer and compositor are converted to linear colour space before
rendering, and gamma corrected afterwards. In essence, this makes all
manual gamma correction with nodes, etc unnecessary, since it's done
automatically through the pipeline.
It's all explained much better in the notes/doc here, so please have a look:
http://wiki.blender.org/index.php/Dev:Source/Blender/Architecture/Colour_Management
And an example of the sort of difference it makes:
http://mke3.net/blender/devel/rendering/b25_colormanagement_test01.jpg
This also enables Colour Management in the default B.blend, and changes the
default lamp falloff to inverse square, which is more correct, and much
easier to use now it's all gamma corrected properly.
Next step is to look into profiles/soft proofing for the compositor.
Thanks to brecht for reviewing and fixing some oversights!
First version of region-scaling. WIP commit, so bear with me a while!
- All fixed sized regions have a small 'drag' widget, on the left or top.
(not yet for free-sized regions, like 4-split).
- Mouse-over on widget changes cursor and allows drag.
- Click on widget hides/reveals.
- Fun for test; 3d view header, if high enough, draws more rows of
buttons when width is too small.
The WIP stuff;
- It doesn't save yet in files, using the "minsize" variable of region
definitions, also means other similar areas show same sizes now.
- Definitions for pref size, min/max will be added.
- Properties panel in Fcurve window draws widget on wrong place when
hidden (subdiv system needs tweak)
- Widgets don't draw perfect yet, also needs further tweaks.
But, in general it's quite fun and usable. :) Many variatians are possible,
like for real tabs, or little icons, or just click-drag on edge.
The reason to first try the widget/tab variation:
- it re-uses the "Area Action Zone" code, widgets for layouting Screens
- it's visible, hotkey-only options for screen layouts are not preferred.
- distinguish clearly area-edges from region-edges this way. Having the
cursor change shape on every edge (and block input) is probably annoying
too... but that can be tested.
Later more!
Notes:
* Sequence transform strip uses G.scene global, this is commented
out now, should be fixed.
* Etch-a-ton code was most difficult to merge. The files already in
2.5 got merged, but no new files were added. Calls to these files
are commented out with "XXX etch-a-ton". editarmature.c and
transform_snap.c were complex to merge. Martin, please check?
* Game engine compiles and links again here for scons/make/cmake
(player still fails to link).
- Volume embed is available as a transform snap option (need new icon). Not as "continuous" as stroke embed, will have to be fixed somehow.
- Transform snaps work in armature edit mode (only snap to mesh, not other armatures, for now). Adding to other edit data type should be easy.
- Strokes can use all the transform snap options plus volume embed.
Bug fix: added small threshold to face snap (and volume embed) to prevent slipping in cracks between faces. More tweaking needed but this now takes care of all the worst cases.
Transform:
First working port of the transform code:
- Object mode only (other conversions need to be ported)
- Contraints (global and local only) working
- Snap (no edit mode, obviously) working
- Numinput working
- Gears (Ctrl and Shift) working
- Only grap, rotate, scale, shear, warp and to sphere have been added as hotkey, but the rest should work too once accessible
- No manipulator
- No drawn feedback other than moving stuff and header print (no constraint line, snap circle, ...)
- No NDOF support
I've only tested Scons support, though Makefil *should* work, I *think*.
Misc:
-QuatIsNull function in arith
-Exporting project_* and view[line|ray] functions from view3d
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r12987:17416
Issues:
* GHOST/X11 had conflicting changes. Some code was added in 2.5, which was
later added in trunk also, but reverted partially, specifically revision
16683. I have left out this reversion in the 2.5 branch since I think it is
needed there.
http://projects.blender.org/plugins/scmsvn/viewcvs.php?view=rev&root=bf-blender&revision=16683
* Scons had various conflicting changes, I decided to go with trunk version
for everything except priorities and some library renaming.
* In creator.c, there were various fixes and fixes for fixes related to the -w
-W and -p options. In 2.5 -w and -W is not coded yet, and -p is done
differently. Since this is changed so much, and I don't think those fixes
would be needed in 2.5, I've left them out.
* Also in creator.c: there was code for a python bugfix where the screen was not
initialized when running with -P. The code that initializes the screen there
I had to disable, that can't work in 2.5 anymore but left it commented as a
reminder.
Further I had to disable some new function calls. using src/ and python/, as
was done already in this branch, disabled function calls:
* bpath.c: error reporting
* BME_conversions.c: editmesh conversion functions.
* SHD_dynamic: disabled almost completely, there is no python/.
* KX_PythonInit.cpp and Ketsji/ build files: Mathutils is not there, disabled.
* text.c: clipboard copy call.
* object.c: OB_SUPPORT_MATERIAL.
* DerivedMesh.c and subsurf_ccg, stipple_quarttone.
Still to be done:
* Go over files and functions that were moved to a different location but could
still use changes that were done in trunk.
Cut gesture: drawing a line with RMB adds exact points (joints in the final skeleton) on strokes. Can cut multiple strokes at once as long as it cuts each one only once (this could be changed).
Shape of the gesture doesn't matter, but eventually it would be straight lines shapes for cuts.
This is an initial commit to get it in SVN and make it easier to work on.
Don't expect it to work perfectly, it's still in development and there's
plenty of work still needing to be done. And so no I'm not very interested
in hearing bug reports or feature requests at this stage :)
There's some info on this, and a todo list at:
http://mke3.net/weblog/volume-rendering/
Right now I'm trying to focus on getting shading working correctly (there's
currently a problem in which 'surfaces' of the volume facing towards or away
from light sources are getting shaded differently to how they should be),
then I'll work on integration issues, like taking materials behind the volume
into account, blending with alpha, etc. You can do simple testing though,
mapping textures to density or emission on a cube with volume material.
the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:
* GLSL support in the viewport and game engine, enable in the game
menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.
* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
An extra texture slot shows up once the last slot is used.
* Memory limit for undo, not enabled by default yet because it
needs the .B.blend to be changed.
* Multiple undo for image painting.
* An offset for dupligroups, so not all objects in a group have to
be at the origin.
All bones marked as no deform are repositioned after the retarget based on their "linked" bone (linked bone is constraint owner if control bone is a target, parent bone if not).
Arithb:
Function to make a quat between two normalized vectors
----------------------------------
Arith:
- axis angle to quat conversion function
- short to float / float to short normals conversion function (eventually, we could go over the go and replace copy/pasted code everywhere)
- ray triangle intersection (to complement the line triangle intersection function)
View:
- viewray / viewline (get near plane point under mouse and ray normal/far point)
Particles:
- extract viewline from brush_add function
This time is was due to different accuracy of floating point computation,
now it uses does a comparison a bit different to avoid this.
Also changed the vectoquat function to be threadsafe.
* BLI_arithb.h - isnan definition is only needed for MSVC, but gcc/mingw complains about it
* file-selectors - moved BLI_storage_types.h or sys/stat.h includes before BLI_winstuff.h includes, to silence warnings about S_ISDIR.
This code adds a basic and simple skeleton generator.
Examples and links are in the wiki, docs will come eventually: http://wiki.blender.org/index.php/User:Theeth/skeletor
In a nutshell, select a vertex at the top of the head and press "Generate Skeleton". UI Panel is in the Editing buttons in Edit Mode, tooltips and semi-useful.
=========
Merge of the famous particle patch by Janne Karhu, a full rewrite
of the Blender particle system. This includes:
- Emitter, Hair and Reactor particle types.
- Newtonian, Keyed and Boids physics.
- Various particle visualisation and rendering types.
- Vertex group and texture control for various properties.
- Interpolated child particles from parents.
- Hair editing with combing, growing, cutting, .. .
- Explode modifier.
- Harmonic, Magnetic fields, and multiple falloff types.
.. and lots of other things, some more info is here:
http://wiki.blender.org/index.php/BlenderDev/Particles_Rewritehttp://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc
The new particle system cannot be backwards compatible. Old particle
systems are being converted to the new system, but will require
tweaking to get them looking the same as before.
Point Cache
===========
The new system to replace manual baking, based on automatic caching
on disk. This is currently used by softbodies and the particle system.
See the Cache API section on:
http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint
Documentation
=============
These new features still need good docs for the release logs, help
for this is appreciated.
NLA Window, Strip blending mode "Add" didn't work at all.
It was using very bad quaternion addition. Replaced with proper code.
For devs; new is the function QuatMulFac(quat, factor) which allows to
multiply a rotation with a value (make it rotate more or less)
====================
The MeshDeform modifier can deform a mesh with another 'cage' mesh.
It is similar to a lattice modifier, but instead of being restricted
to the regular grid layout of a lattice, the cage mesh can be modeled
to fit the mesh better.

Implementation Notes:
- OpenNL has been refactored a bit to allow least squares matrices to
be built without passing the matrix row by row, but instead with
random access. MDef doesn't need this actually, but it's using this
version of OpenNL so I'm just committing it now.
- Mean value weights for polygons have been added to arithb.c, a type
of barycentric coordinates for polygons with >= 3 vertices. This
might be useful for other parts of blender too.
Mat3ToScalef and Mat4ToScalef
These return a floating point scale value which is the average of the 3 axies.
Use this to adjust curve radius when applying scale/rot
