The real bug is in the matrices blending function which doesn't handle non-uniform scaling correctly.
I've minimized the occurence of the bug by calling the blending function only when the influence is smaller than one (woah, optimisation AND bug fix!)
This should make the bug disappear approximatly 90% of the time since people don't use influence all that often (also, this only applies to constraint that are alone, not using influence IPOs to switch between two constraints).
I'd solve the blending function bug, but I haven't had much time to dig into it really.
Incidently, by reverting to the previous code, this solves bug #1069http://projects.blender.org/tracker/index.php?func=detail&aid=1069&group_id=9&atid=125
Basically this provides three new things:
1. Choice of a list of noise-base functions, which can be used by the
current Clouds, Marble, Wood textures as well.
2. Three new texture types: Musgrave, Voronoi and DistortedNoise
3. Python access to noise functions (not for render!)
All of this together makes Blender's builtin procedural textures a LOT
more powerful. Here again, a full webpage should be made to show off all
possibilities, and explain some of the more scientific names for settings.
A good read on Musgrave textures can be found here:
http://www.ypoart.com/Downloads/Musgrave.htm
About Voronoi:
http://www.ypoart.com/Downloads/Worley.htm
I can't find official DistortedNoise docs easily... maybe its something
Eeshlo created himself.
I've spent some time to change the patch Eeshlo provided. Worth noting:
- created main texture "Musgrave" with 5 sub choices (instead of 5 new
main textures)
- added for all new textures the option to scale (zoom in out)
- added patch in do_versions to initialize variables
I hope the Python team will check on the Noise.c API. And include in docs!
binary subformats, and writes the binary subformat. Read is done with
usual F1, write is done in the menu 'File->Export Selected->STL'. Writes
meshes only, writing the 'displistmesh' if subsurf is on. The 'magic'
to determine whether it is reading the binary or ASCII subformat
could use a little work, but makes the correct choice most of the time.
[SCons] Build with Solid as default when enabling the gameengine in the build process
[SCons] Build solid and qhull from the extern directory and link statically against them
That was about it.
There are a few things that needs double checking:
* Makefiles
* Projectfiles
* All the other systems than Linux and Windows on which the build (with scons) has been successfully tested.
- added mesh_set_smooth_flag, mesh_delete_material_index function
- isolated some globals
- got rid of reliance on meshdata in buttons_editing.c and material.c
(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.
* Created a MESH_MAX_VERTS macro in DNA_mesh_types.h
* fixed vert limit for converting displistmesh ==> mesh
* fixed vert limit when doing boolean operations
of zr). This struct was never written to file and the new 'int based'
MFace can be used in it's place. Some removal of redundant code could
perhaps be done now (I didn't do any though, just "s/MFaceInt/MFace/").
different objects shouldn't share flags this way (still sharing of
other mesh flags in renderer... ickity pickity, but I'm not fixing now)
- removed some unnecessary uses of DNA_mesh_types.h
* Blender static now links. By default this option is disabled on all
platforms. Simply set the option in config.opts to 'true'.
* Added the following flags to config.opts:
- HOST_CC. This is the C compiler for the host platform. This value is the
same as TARGET_CC when not cross compiling.
- HOST_CXX. This is the C++ compiler for the host platform. This value is
the same as TARGET_CXX when not cross compiling.
- TARGET_CC. This is the C compiler for the target platform.
- TARGET_CXX. This is the C++ compiler for the target platform.
- TARGET_AR. This is the linker command for linking libraries.
- PATH This is the standard search path
All SConscript files have been updated to reflect these changes. Now it's
possible to change only the root SConstruct file, and all compiler specific
variables are passed automatically to all SConscript files. Of course, this
does not apply to makesdna because there the host and target platform is
different from all other libraries.
To pass a variable that applies to all platforms, all we now have to do is
set the correct value in library_env
Note: as usual, to get the latest options in the config.opts file, first
remove your version.
* Removed the I18N_DEFINES from the config.opts file. This define is not a
user setting. The defines depend on what options the user enables in the top
of the config.opts file (USE_INTERNATIONAL).
* Moved the defines to the correct SConscript files.
Only the relevant libraries now use these defines.
* Windows fix for the python settings. There were missing brackets [ and ] for
these settings.
* libraries are now generated in [BUILD_DIR]/lib
* passed the user_options to all libraries now.
This means I could remove a couple of Export/Import lines.
* Changed the order in source/blender/src/SConscript and
source/gameengine/SConscript.
All libraries are now sorted alphabetically. This has no impact on the build
process.
* Armatures that had constraint targets inside other armatures
weren't transform()-ing correctly
* Issues with lattice deformed objects that are parents of bones
when rendering an animation. Seems to be mostly OK now with the
exception of the first rendered frame -- weird bugs like this have
plagued blender for ages, which leads me to believe that
RE_rotateBlenderScene() is a piece of garbage that nobody understands
(especially me).
* made a few helper functions to clean up some repeated code related
to clearing constraint status and rebuilding displists.
it by precalculating all needed Osa vectors when rendering glass, this
because it is unpredictable what is exactly going to be needed after.
- a hint that this should be done better is in the code... will mostly
improve sharpness and a bit rendertime though
(thanks bugmaster intrr!)
- G.f's G_DEBUG flag was being erased in blenkernel/intern/blender.c's
setup_app_data:
G.f= bfd->globalf
// added a line above it to fix this:
if (G.f & G_DEBUG) bfd->globalf |=G_DEBUG;
G.f= bfd->globalf;
BPython:
- debug info now only shown if Blender is started with '-d' option
- added ~/.blender/scripts to modules sys.path
- added two new functions to Blender.sys: basename and splitext
- added doc for Blender.sys, updated other docs
recalculate the O.dxno and O.dyno for each pixel. This causes scanline
errors (stripes) when in same scanline something else is called that
calculates O.dxno/dyno...
by the seed variable. Requested by S68.
Basically they move slightly when you change the seed. Might be
a good idea to split this up so there are two seed options in a
particle effect, however there are already quite a bit of them so I opted
for this.

-- removed struct Script (DNA_script_types.h) from makesdna to blender/include/BPI_script.h
(BPI meaning Blender Python-related external Include file).
Had agreed with Ton that makesdna was not the proper place for it.
-- fixed two small warnings in Ipo.c (variables might be used uninitialized)
-- fixed a bug reported on blender.org's python forum by Wim Van Hoydonck (aka tuinbels):
Blender would hang if a script failed. My fault, accidentally put a node=node->next type call outside the while loop check, so it never ended.
With makesdna/DNA_script_types.h removed and include/BPI_script.h added, msvc projectfiles will need to be updated. Sorry to do it now, but I promissed I'd fix this before next release.
- removed rendermesh_uses_displist (no longer relevant)
- converted appropriate me->flag tests to using mesh_uses_displist
- made vert and face counting (for info header) use proper counts
- changed flip_subdivision to allow level==0 argument
- ps. thanks for subsurf orco fix ton
- reduced main subsurf interface to two functions to make DispListMesh
structures from an editmesh or a regular mesh. for the most part this
means that to implement a geometry modifier you only need to write
these two functions (not very plugable yet however).
- added displistmesh_from_mesh and displistmesh_from_editmesh functions
which allow simple support of subdivLevel(0) subsurfs, somewhat handy
for testing things (like why orco doesn't work for subsurf).
re-using old one. New one = 'exp'.
- at first I used the old 'exposure' value, and just mapped it to 0. this
causes a problem with upward compatibility, old blenders then render a
black picture. is too confusing!
- warning; exposure values saved with commit of last week will get lost.
- changed code to make use of actual textures, not the hackish
'externtex', which is only for tools
- added a 'displacement' vector in ShadeInput, and moved calculation of
displacement vector to texture.c itself. So it works with stencil, but
also for options as 'add', 'mult' and 'sub'.
- for RGB textures it uses the brightness value of color for displace
- for stucci, and plugin textures returning a normal, it uses that
- Also: wrote call in end of preparing renderfaces, to split non-flat
quad faces in triangles. gives a lot fewer errors in displace textures,
but also raytracing irregular subsurfs goes better now.
- texture mapping that works for displace: orco, sticky, global, obj, normal.
UV not yet. Reflection-displace? uhh! :)
yet (R.vn and R.vlr no longer exist, and were needed to get the image mapped
right). Works esp. well with Subsurfs. Sensitive to vertex normal issues
in Simple and Mesh modes.
-Also porting Simple Subdivide. Subdivides mesh at rendertime w/o changing
shape, for smooth displace and Radiosity.
-Removed an unused var from KnifeSubdivide.
Materials are exported the best we can do by now. It will look almost as in
blender except for the missing procedural textures and some minor issues.
You have to tweak normal modulation amount to get the desired result cause
is not the same in yafray.
We added a panel in render space to adjust some yafray settings (GI and so)
Also we export transparency and reflection using new raytracing settings,
but that will be changed and improved soon.
Remember that you have to set YFexport path in user defaults and yafray must
be on path (version 0.0.6)
We added the "yafray" button to activate all this stuff in the render window.
Panel and settings are only shown when checked.
So now when activated the code calls yafray export instead of the internal
renderer and finally the resulting image is loaded back into render window's
buffer. So animation is also possible and results can be saved using blender
usual scheme.
You'll need SCons (www.scons.org) to build.

Thanks to IanWill for a bugfix in the Linux build.
Note: This is a work in progress. A lot still has to be done - for example the
optional parts are only to be enabled by directly setting 'true' or
'false' in the SConstruct file. This needs to be moved to a user config
file. Also, the .o/.obj files are stored in the source tree. This needs
to be fixed as well.
The game engine is not yet built.
----------------------------
Another (major) armature speed up for bones with many constraints.
When tranform()-ing, figure out which bones need to be recalculated
beforehand and only update those bones.
--------------------------
Major speed up for armatures during times when you aren't
posing a figure.
Background: the calculation of poses generated by actions and the
calculation of displists were getting somewhat out of sync.
This was being remedied by 'clearing the constraint done flag'
of the pose channels and recalculating the displists every time
the 3d view was redrawn, making life slow and unpleasant.
Commenting out the code that was doing this, then reinserting
the 'clearing the constraint done flag' at the right times
made things a bit more perky.
