Removed all limitations from render code for maximum threads. The only
define for this now is in BLI_threads.h, and currently set to 8.
Note that each thread renders an entire tile, and also allocates the
buffers for the tiles, so; more threads might work better with smaller
tiles.
IMPORTANT: node system won't work yet with more than 2 threads! So, don't
try material nodes or compositing with over 2 threads. That I'll commit
later today.
What does work (should work :) is AO and soft shadow now.
This bug was caused by broken's recent patch to make the Curve modifier
determine its axis from the modifier panel, rather than the object's track
axis. In the case where a Curve modifier is applied by parenting the object
to the curve, the curve axis needs to be copied from the object's track axis
in modifiers_getVirtualModifierList(). This commit adds the necessary copy.
Vertex/Face/Frame duplication now draws using OpenGL display lists. Makes
drawing go much faster (2-5 times, depending on size of duplicated object).
This system uses boundbox checks too, so outside of view it draws faster.
Note for face duplication: I've fixe a bug for incorrect alignment when
the parent was rotated when a parenting happened, the 'inverse parent
correction matrix' then messed up alignment. For face duplication it now
works OK, but for vertex-dupli not... need a way to fix this backwards
compatible.
center, rotated according to face edges, and optionally with scale of the
face.

Also: bugfix in undo/redo for relinking data to the UI. It was not checking
for Library data, accidentally linking non-library data with same names.
When linking a referenced (Library) Image to a texture face, it wasn't
tagged to become saved in file. So you lost data.
Also fixed: tooltip for the "Li" icons was wrong.
freed. Windows nicely crashes then.
Also: added human readable string in fileglobal, so you can check the
subversion in a file manually too. Rule:
- Find GLOB chunk (first chunk after REND now)
- skip sizeof BHead, 20 bytes in 32bits, or 24 in 64 bits
- there's 4 characters showing subversion, right now it reads " 1".
Next to the release code, a subversion number is written in the file
now. This is in the chunk GLOB, which is now in beginning of file.
Subversions can be used to have finer control over do_versions(), so you
don't have to wait for a release to patch stuff nicely. We can also
increase these subversions regularly to denote important changes.
If a subversion is not 0, it's being printed in the header, so a user can
also verify the state. (We might even tag cvs for it?).
Next to this, a minimum version and subversion number are written too.
From now on, if you change files in a way a past binary cannot read this
nicely anymore, you should set these minima to the current version.
This was especially added for the new mesh layers, which will not work
for older binaries once we make 2.43.
Ancient bug: texteditor input was limited to "isprint()" characters, the
default non-accented simple ascii set. I've removed that.
Now we still have a conflict with hotkey handling, so ALT+character input
won't work. But, for keyboards that have special character keys from itself,
this patch will allow typing them in Text now.
Array Modifier type "path length" didn't force a path calculation on load.
Note that this is still improper handling in Blender... an exception that
has to move to the depsgraph.
library .blend files anymore, making it a load faster to use.
- Fixed ancient annoyance; samples were not properly freed, giving a lot
"Error Totblock" when using sound.
This fix also involves removing an ancient NaN hack, which treated the
samples as fake Library data in the Main database.
But still, the Blender Sound and Sample code is horrible... :/
nice little 'debug' feature
SHIFT_ESC breaks baking without throwing away the baked keys
so you can check the solution calculated so far
baked sb replay checks for NULL pointers in keys -> motion will stop there
even saving and loading to file works here,
but i would not expect it to do so
humm .. may be i'll add a dirty flag for that
Crash using Shape Widget Wizard script, was an error in customdata copy.
The script still throws a python error though, but that seems unrelated
to this crash.
Added a callback instance_init() so that any particular instance of a
texture plugin can initialize data. Updated the clouds2 and tile example
plugins to have a (dummy) call back.
- New perspective projection capability. If a camera is used as the
projection object, the modifier detects whether to do perspective or
orthographic projection based on the camera type. If any other object
type is used as the projection object, orthographic projection is used.
- Orthographic projection actually works properly now.
- The projected UVs are scaled and offset so that the image is centred in
the projecting camera's view.
- AspX and AspY inputs have been added to control the aspect ratio of the
projected UVs.
Also:
- I have added the Mat4MulVec3Project() function to BLI_arithb.h; this
function converts a 3-dimensional vector to homogeneous coordinates
(4-dimensional, with the 4th dimension set to 1), multiplies it with the
given matrix, then projects it back to 3 dimensions by dividing through
with the 4th dimension. This is useful when using projection matrices.
Random seeding is still not perfect in render, especially lack of good
thread support still.
- VectorBlur node was calling seed for each exec, causing other nodes to
get fixed random too.
- added seed in non-OSA main loop for render
- use BLI_srandom, is better than BLI_srand
CurvePaths: if the path has vector handles, or when it's a Poly curve, the
amount of interpolated points on the path was too limited (6 actually).
Now the 'resolu' of the curve defines the amount of interpolated points.
This enables motionpaths or deforming with sharp corners.

Fix for bug #5250: inaccurate conversion between edit and pose mode bones.
Two very bad bugs:
- replacing atan() with atan2() should also remove the M_PI correction!
This is the equivalent:
angle=atan(x/y); if(y<0) angle+=M_PI;
angle= atan2(x, y);
- the new NormalizedVecAngle2() call was negating an input vector, causing
calling code to screw up. All arithb.c calls should not alter input.
Yesterday's commit from Brecht broke armature editmode, damaging armatures
in a way you cannot rescue. This rewinds the main changes. After commit
I'll try to find the error...
- Curve/Nurbs/Font/MBall now all draw arrays.
- had to flip abgr to rgba in shaded drawing
- Mesh drawing can't be easily done; the indices for faces are not in
in one chunk. Also need a way to gether trias/quads, per material.
Speedup results are mixed. Something between 2-4 times. Especially for
text it seems to help.
that vertices will be individually displaced in the X, Y and Z directions
by the RGB components of the texture (R affects X, G affects Y, B affects Z).
This can be used along with e.g. the colour Clouds texture for a jitter effect.
Wave Modifier
This patch allows the option to use an object to determine the wave modifier's
start X & Y, it also allows for animated objects giving a moving wave
start X & Y.
Thanks to Michael Fox for the patch!
- After making a Group, internal socket values are now copied to the
group node, so an execute will give identical results
- After ungrouping, the cyclic dependency tagging didn't work well in
all cases, showing a red noodle line and giving composite errors.
For time being solved by calling the NodeSort twice.
- Viewer nodes now get previews updated always (used to be only the active)
Note: this is not for previews inside of groups!
All data layers, including MVert/MEdge/MFace, are now managed as custom
data layers. The pointers like Mesh.mvert, Mesh.dvert or Mesh.mcol are
still used of course, but allocating, copying or freeing these arrays
should be done through the CustomData API.
Work in progress documentation on this is here:
http://mediawiki.blender.org/index.php/BlenderDev/BlenderArchitecture/CustomData
Replaced TFace by MTFace:
This is the same struct, except that it does not contain color, that now
always stays separated in MCol. This was not a good design decision to
begin with, and it is needed for adding multiple color layers later. Note
that this does mean older Blender versions will not be able to read UV
coordinates from the next release, due to an SDNA limitation.
Removed DispListMesh:
This now fully replaced by DerivedMesh. To provide access to arrays of
vertices, edges and faces, like DispListMesh does. The semantics of the
DerivedMesh.getVertArray() and similar functions were changed to return
a pointer to an array if one exists, or otherwise allocate a temporary
one. On releasing the DerivedMesh, this temporary array will be removed
automatically.
Removed ssDM and meshDM DerivedMesh backends:
The ssDM backend was for DispListMesh, so that became obsolete automatically.
The meshDM backend was replaced by the custom data backend, that now figures
out which layers need to be modified, and only duplicates those.
This changes code in many places, and overall removes 2514 lines of code.
So, there's a good chance this might break some stuff, although I've been
testing it for a few days now. The good news is, adding multiple color and
uv layers should now become easy.
Minor change to to how luminance detail is added to alpha channel in chroma key node.
Removed unused inputs in chroma key and luminance key nodes.
Changed chroma key controls back to sliders because I think they offer the user a more intuitive interface to the node.
Here's the full release log with example file.

For people who don't read docs; just press ALT+CTRL+B on a Mesh
with texture faces!
Todos:
- maybe some filter options extra?
- Make normal maps in Tangent space
Bugfix #5027: Deleting Shape key sometimes caused corruption to Ipo curves.
sort_key() was moving key but not resorting adrcodes for keys and Ipo curves.
Also changed behavior of sort_key() so that it only resorts one key; all the
places which currently call it only do so after changing one key (the
previous code was moving the key one location at a time through the keyblock
list).
Using acos(dot(u, v)) to find the angle between two vectors is quite
inaccurate, and there's a better way to do it, as explained here:
http://www.plunk.org/~hatch/rightway.php
Also changed the use of atan for computing roll to atan2 in some places,
the latter avoids accuracy and division by zero issues.
Composite: Rotate and Scale nodes ignored the translation offset.
I've added rotating and scale of offset vector, but this should become a
nice 2d matrix[3][3].
Also fixed: the call "pass_on_compbuf" now has correct handling for
using duplicate buffer rects. Can be used safely again to migrate input
buffers to the output when no operation happened. This makes translate
node faster again btw.
I wonder how this survived so long in Blender... (2005/03/09 commit).
Reason was the call to BPY_free_screen_spacehandlers(sc) in kernel,
which was freeing up scripthandlers in a weird way. That call is
really obsolete. The real freeing should go in the del_area() call,
to prevent copying and deleting area in the UI to go wrong.
(Crash happened in testing timeline markers, and holding CTRL+Uparrow
a while...)
IDProperties now have a sanity check to prevent different ID properties
in the same group from having the same name. The appropriate code has been
added to the python bindings to catch this and raise an error.
This commit adds file reading/writing of ID properties to all ID types,
and also adds python access for NMesh, Mesh, Scene and Image. Note
that the file reading code might need some more work for certain
future/planned features to save right. Also I updated a few comments in idprop.c.
This commit adds supports for per-ID properties to blender.
See http://mediawiki.blender.org/index.php/BlenderDev/ID_Property
for more information on how it all works.
ID properties are accesable by python; but note that
bindings have only been added to Object and Material thus
far. However adding more bindings is easy and I plan
on adding several more hopefully within an hour of this inital
commit.
A generic UI panel is also planned, that will go wherever its
needed; for example in the material buttons, editing buttons, etc.
I'll likely submit the initial code for that as a patch, though,
so matt and ton and others can go over it and make sure it's
all good. :)
VERY important, if you intend to use ID properties please
go to http://mediawiki.blender.org/index.php/BlenderDev/PropertyStandards
and start writing the appropriate standards for it.
