Files created in blender before this revision should be rendered in
exactly the same way they used to render before.
Patch by Morten Mikkelsen, finished by Ton and me.
threading to no longer sleep 50ms for each object, using work queue now.
Also it was showing SSS preprocessing while actually doing Volume precaching,
fixed as well.
- move some larger vars into a nested scope.
- replace memset with zero initializer.
- rempace VECCOPY macros with copy_v3v3
- change function args to give the float array length.
- converting nurbs to mesh was casting the material to unsigned char.
- subsurf was casting to char, then int -> short in a loop.
- have material functions take & return shorts.
- define __BIG_ENDIAN__ or __LITTLE_ENDIAN__ with cmake & scons.
- ENDIAN_ORDER is now a define rather than a global short.
- replace checks like this with single ifdef: #if defined(__sgi) || defined (__sparc) || defined (__sparc__) || defined (__PPC__) || defined (__ppc__) || defined (__hppa__) || defined (__BIG_ENDIAN__)
- remove BKE_endian.h which isn't used
Volume pre-caching altered shared data simultaneously in multiple threads, causing invalid scattering results when "Asymmetry" value was used. The view vector is now passed as a function argument.
- use 'const float *' and array size in some function declarations.
- replace macros for BLI_math functions INPF, VECCOPY, VECADD etc.
- remove unused VertRen.clip struct member.
- remove static squared_dist() from 2 files, replace with BLI_math function len_squared_v3v3().
- use vertex arrays for drawing clipping background in the 3D viewport.
This would previously break because begin/end functions for each tree type still have some checks of the ntree->execdata pointer in them, despite the intended use of execdata instances instead of trees themselves for execution data storage. This is an artifact of the old execution system that required these checks to be made in the functions to avoid multiple execution of top-level trees. Now these functions take an additional argument, so group nodes can prevent them from setting and checking the nodetree->execdata pointers.
This branch adds mostly organizational improvements to the node system by renaming the node folders and files. A couple of internal features have been added too.

--- text from the patch.
Recently Campbell Barton added callback functionality for Python's usage, but this only includes pre- and post-render callbacks. There are no callbacks for the duration of the render. This patch adds the few lines required for executing a callback while Blender Render is working. The callback resides in the rendering pipeline stats function, so whenever statistics are printed, the callback is executed. This functionality is required if one wants to:
1) Observe what is happening while Blender is rendering via the command line
2) Add custom statistics that Blender prints while the renderer works
3) The user wants to continue executing his Python script without the code halting at bpy.ops.render.render()
Personally I'm currently using this for printing out more detailed progress reports at Renderfarm.fi (such as CPU time, time spent rendering, total progress in regards to the entire rendering process). Tested on Windows, Linux and OS X.
Example on how to use the callback:
def statscall(context): print("Thanks for calling!")
bpy.app.handlers.render_stats.append(statscall)
bpy.ops.render.render(animation=False, write_still=True)
from Tom Edwards (artfunkel), with minor edits.
This patch makes the following improvements to environment map scripting:
* Adds a "is_valid" RNA property to envmaps. True if the map is ready for use, False if it needs rendering.
* Adds a "clear" RNA function to envmaps. Deletes any envmap image data.
* Adds a "save" RNA function to envmaps. Writes the envmap to disc with a configurable layout. (Defaults to the current hard-coded layout.)
* Updates bpy.ops.texture.envmap_save with configurable layout support as above.
These changes, particularly configurable layouts, make exporting envmaps to other software much easier.
