The locality is restricted to action or user-transform only. Or as it goes
in the code now: by setting a constraint local, it executes the constraint
before it calculates the influence of Action or user transforms.
ALso note that this works in Evil Eulerians. Meaning that when you only
want to copy the X,Y or Z compenent of a euler, it can give unpredictable
results when the other euler values are set, this because euler axis
rotations work on top of each other.
Previously, using the "Stride Bone" tried to get that Bone motionless on
the path by correcting the internal time of the Action. This however caused
too many problems, especially with irregular walks.
The new system also tries to keep the Stride Bone motionless, but this by
moving the entire armature, and not changing the timing of the Action.
Give much nicer results. :)
To make editing Strides easier, I've added a new option in the NLA
panel to disable the path. This way you can quickly switch to editing the
action itself (keying the stride bone) and viewing the result.
- update for the old mathutils rewrite
- update for some other methods ive added
- added explaination of wrapped data
- added a .css file for epydoc gives nice blender/python colors :?
- Bone Ghost drawing now skips axes and names
- "Snap to cursor" now works for parent-less bones in PoseMode
- Prevented assigning in buttons of negative zero (was confusing)
- Copy Location Constraint didn't update Object when it was copying from a
Bone
- Deleting bone in editmode, and connecting bones crashed due to evaluation
of deformation code (only allowed for pose).
on top of each other. Was 100, which gave noise like this in this image;
http://www.blender.org/bf/hairnew.jpg
Made it 200, which solves it for a million hair polygons;
http://www.blender.org/bf/hairnew1.jpg
Also note that hair renders go much faster and better if you insert a real
solid head in it, that will prevent hairs on the back to be inserted in the
buffers. ANd don't make the head Ztransp!
I've been going over the zbuf.c code, which is indeed very ancient,
with a load of old optimizing and redundant code in use.
Added more 'modern' Span support, which fills per face two arrays
with the scanline information in it. That way you can zbuffer a quad in one
run as well. It was also exactly that code that's copied all over in zbuf.c
For now, to prevent issues for the release, the 'render a quad in 1 run' is
only in use for the strand render. Tests reveil a speedup of about 33%.
Will work on this recode later... which would also result in making zbuf.c
threadsafe.
And: bugfix #3398
When using the new 'render emitter' for particles, the orco array for
particles was accidentally used by mesh too.

- added width control for strands
- made tangent (anisotropic) render an option
(so you can render strands more solid, like metal/wood)
Also:
- ALT+A anim playback with static particles made cursor flashing
in case the paste buffer+length of text was bigger than MAXTEXT ->
fixed this, also a error is shown to the user now. editfont.c needs
still some cleaning but will discuss about this with kaito and intrr.
"Additive" Guides. See also:
http://www.blender3d.org/cms/New_Particle_options_a.721.0.html
This Guide type uses the falloff distance to also define how much the
particle (or hair strand) goes over the path, allowing to create local
extremes, or only local particle generating or hairgrowth. Nice for
spiky haircuts!
Note that the current default generates particles based on the original
amount of vertices and faces, this for vertex group support (which is not
subdivided with modifiers). That means that particles generated on
subsurfed faces still have minor approximation errors.
Note for DerivedMesh users; I've added a new API call:
float *mesh_get_mapped_verts_nors(Object *ob);
Which returns an array of 2 * 3 * float size, containing the vertices and
normals, deformed and subsurfered, but only the original me->mvert amount.
Works in all non-editmode cases.
Is in use now for vertex/weight paint and particles.
- "Disp" option allows to go back to zero, effectively disabling the entire
particle generating.
- When parenting guides to an emitter the depgraph sees a cyclic relation,
which caused not updating the particles correct on loading it.
- Moved creating guide Cache completely outside of the particle loop,
should make it faster to use with large amounts of particles and objects.
When using the pulldown menus for exiting weightpaint, it did not free
octree tables for weightpaint, giving an error message on re-entering
weightpaint.
* add some protection against accessing MVerts/MEdges/MFaces which have
been deleted
* correct cut-and-paste bug in faces.delete() method
* correct some compiler warnings
underline stuff) as well.
Attempt at fixing editmode undo, but not successful. I'll create a bug-
report and assign it to Mika, because I only understand "train station"
(German saying :-) when looking at the code.
table stable... you keep correcting leg sizes until no table is left
anymore! :)
This commit restores the displacement direction from 2.37a code, which was
negated 5 months ago to fix a change in renderconverter.c, but somehow is
not needed anymore. The regression displacement file now renders OK again.

It uses Material color and specular, like for the solid faces.

There's no doubt this patch had a lot of good ideas for features, and I
want to compliment Janne again for getting it all to work even!
A more careful review of the features and code did show however quite some
flaws and bugs... partially because the current particle code was very much
polluted already, but also because of the implementation lacked quality.
However, the patch was too good to reject, so I've fixed and recoded the
parts that needed it most. :)
Here's a list of of most evident changes in the patch;
- Guides support recoded. It was implemented as a true 'force field',
checking all Curve path points for each particle to find the closest. Was
just far too slow, and didn't support looping or bends well.
The new implementation is fast (real time) and treats the paths as actual
trajectory for the particle.
- Guides didn't integrate in the physics/speed system either, was added as
exception. Now it's integrated and can be combined with other velocities
or forces
- Use of Fields was slow code in general, made it use a Cache instead.
- The "even" distribution didn't work for Jittered sample patterns.
- The "even" or "vertexgroup" code in the main loops were badly constructed,
giving too much cpu for a simple task. Instead of going over all faces
many times, it now only does it once.
Same part of the code used a lot of temporal unneeded mallocs.
- Use of DerivedMesh or Mesh was confused, didn't work for Subsurfs in all
cases
- Support for vertex groups was slow, evaluating vertexgroups too often
- When a vertexgroup failed to read, it was wrongly handled (set to zero).
VertexGroup support now is with a name.
- Split up the too huge build_particle() call in some parts (moving new code)
- The "texture re-timing" option failed for moving Objects. The old code used
the convention that particles were added with increasing time steps.
Solved by creating a object Matrix Cache.
Also: the texture coordinates had to be corrected to become "OrCo".
- The "Disp" option only was used to draw less particles. Changed it to
actually calculate fewer particles for 3D viewing, but render all still.
So now it can be used to keep editing realtime.
Removed;
The "speed threshold" and "Tight" features were not copied over. This
resembled too much to feature overkill. Needs re-evaluation.
Also the "Deform" option was not added, I prefer to first check if the
current particle system really works for the Modifier system.
And:
- Added integration for particle force fields in the dependency graph
- Added TAB completion for vertexgroup names!
- Made the 'wait cursor' only appear when particles take more than 0.5 sec
- The particle jitter table order now is randomized too, giving much
nicer emitting of particles in large faces.
- Vortex field didn't correctly use speed/forces, so it didn't work for
collisions.
- Triangle distribution was wrong
- Removed ancient bug that applied in a *very* weird way speed and forces.
(location changes got the half force, speed the full...???)
So much... might have forgotten some notes! :)
-- calling mesh.getFromObject(obj) with mesh object now also
copies material properties
-- mesh.quadToTriangle() takes a parameter to duplicate both
Ctrl-TKEY and Shift-Ctrl-TKEY actions
-- assigning None to mesh.verts "clears" the memory allocated
to the mesh (equivalent of Mesh.New(), but on an existing
mesh)
-- exception handler message for mesh.faces[i].uv = [..] more
clear (uv attribute only accepts tuple, not list)
-- fixed bug for meshs with deformed verts when deleting verts
(deformed verts deleted and repacked correctly now, I think)
bug #3367 reported by Chris Want (thanks): ob.mat documentation was
wrong (was not updated); that attribute returns the world space matrix,
not the local one.
