if theres very few faces its not worth it to create a separated tree for beinng reused.
should speedup some particle renders.
This "fixes" a bug relationed with a arithmetic precision on instances and raytrace of very close objects
which usually happens on rendering (almost) overlapping alpha-enabled leafs/feathers
This brings back sequencer rendering, moving do_render_seq() into the
pipeline where it belongs.
Things to fix: SCENE-strip rendering and memory cleanup for
SCENE-strips.
Otherwise: enjoy :)
lay = result.layers[0]
lay.rect_from_file("somefile.png", part.x, part.y)
If the source image is bigger then the render layer x/y offsets can be used to choose the part of the image use.
* Diffuse/specular ramps works again.
* Wire is now a material type next to Surface and Halo.
* Removed Volume material type option until it is actually there.
* Some button layout tweaks.

An engine to use for output can now be selected an influences what
shows in the buttons window, only showing relevant data. The idea
behind this is to make it more clear what is supported where, make
the system more pluggable for external render/game engines, and save
space hiding stuff that is not relevant anyway.
* Top header now has an engine menu, to choose between the blender
render engine, game engine, and other future external engines.
* If the game engine is enabled, the buttons window should show
only properties that work in the game engine, and similarly for
the render engine.
* Moved panels from the logic space and game tabs to the physics,
scene and world tabs instead, and removed the game tab.
* Materials and textures tabs should eventually become game
specific too, to better show what is supported.
This adds a RenderEngine type to RNA, which can be subclassed
in python (c++ will follow once we support subclassing there).
It's very basic, but plugs into the pipeline nicely. Two example
scripts:
http://www.pasteall.org/6635/pythonhttp://www.pasteall.org/6636/python
Issues:
* Render runs in a separate thread, and there is unrestricted
access, so it's possible to crash blender with unsafe access.
* Save buffers and full sample are not supported yet.
* 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.
Patch by Alfredo de Greef. Considerably improves the quality of bump
mapping, and texture filtering for displacement and warp too. Mainly
this is achieved by getting the texture derivatives just right in
various cases, many thanks to Alfredo for figuring this one out, works
great.
This is enabled by default now, but disabled still for existing
textures to preserve backwards compatibility. Can be enabled with
the "New Bump" option in the material texture slot in the outliner.
Also, I made the range for the normal factor a bit smaller since this
gives stronger effects, but note that you can still type in larger
values than the slider allows.
Patch by Alfredo de Greef with high quality image texture filters.
This adds 3 new filters:
* SAT: Summed Area Tables. This is like mipmaps, but using somewhat
more memory avoids some artifacts.
* EWA: Ellipitical Weighted Average, anisotropic filter.
* FELINE: Fast elliptical lines for anisotropic texture mapping.
The one change I made to this was to try to fix an alpha/premul
problem, hopefully I didn't break anything, it looks compatible
with the existing filter now for me.
- 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!
It creates a tree cut after knowing that a given point will pass on a BB.
This tree cut is used to accelarate the rays casted from a given BB, eliminating unnecessary BB tests from root till the tree cut.
* UI layout for scene buttons has quite some changes, I tried to
better organize things according to the pipeline, and also showing
important properties by default, and collapsing less important ones.
Some changes compared to 2.4x:
* Panorama is now a Camera property.
* Sequence and Compositing are now enabled by default, but will only
do something when there is a node tree using nodes, or a strip in the
sequence editor.
* Enabling Full Sample now automatically enables Save Buffers too.
* Stamp option to include info in file is removed, it now simply always
does this if one of the stamp infos is enabled.
* Xvid, H.264 and Ogg Theora are now directly in the file format menu,
but still using FFMPEG. Unfortunately Ogg is broken at the moment
(also in 2.4x), so that's disabled. And Xvid crashes on 64bit linux,
maybe solvable by upgrading extern/xvidcore/, using ubuntu libs makes
it work.
* Organized file format menu by image/movie types.
Added:
* Render layers RNA wrapped, operatorized, layouted.
* FFMPEG format/codec options are now working.
Defaults changed:
* Compositing & Sequencer enabled.
* Tiles set to 8x8.
* Time/Date/Frame/Scene/Camera/Filename enabled for stamp.
* Objects now support up to 32767 material slots. It's easy to
increase this further, but I prefer not to increase the memory
usage of mesh faces, it seems unlikely that someone would
create 32767 distinct materials?
* Forward compatibility: the only thing you can potentially lose
reading a 2.5 file in 2.4 is object linking (instead of default
data), though usually that will go fine too. Reading files with
> 32 material slots in 2.4 can start giving issues.
* The ob->colbits variable is deprecated by the array ob->matbits
but I didn't remove the ob->colbits updates in very few places
it is set.
* I hope I changed all the relevant things, various places just
hardcoded the number 16 instead of using the MAXMAT define.
* Join Objects operator back. This is using the version from the
animsys2 branch coded by Joshua, which means it now supports
joining of shape keys.
* Fix for crash reading file saved during render.
- Keyed targets in one list instead of "chaining", this opens up many more possibilities than before and is much less obscure.
- Better keyed timing possibilities (time & duration in frames).
- Looping over keyed targets list.
Other changes:
- New child setting "length" with threshold (great for guard & underfur with a single particle system)
- Modularization of path interpolation code.
- Cleared "animateable" flags from many particle settings that shouldn't be animateable.
Fixes:
- Keyed particles weren't copied properly (ancient bug).
- Hair rotations depended on global z-axis for root rotation so downward facing strands could flip rotation randomly. Now initial hair rotation is derived from face dependent hair matrix. (This caused for example ugly flipping of child strands on some cases).
- Children from faces weren't calculated straight after activating them.
- Multiple disk cache fixes:
* Disk cache didn't work correctly with frame steps.
* Conversion from memory cache to disk cache didn't work with cloth.
* Disk cache crashed on some frames trying to close an already closed cache file.
* Trails didn't work with disk cached particles.
- Child rough effects were effected by emitter object loc/rot making them next to useless with animation, why didn't anybody tell me this!!
- Lots of random code cleanup.
*Added vbvh - Just a experimental tree type :)
Variable Way BVH - there is no hardcoded number of childs per each Tree Node
- idea is to optimize a tree to reduced the expected number of BB tests even after applying SAH (for that an hardcoded n-way is not enough)
- for now childs are stored on a linked list
to be able to use C++ at raytrace code
C++ used in here is basicly C with templates and function overloads,
to make it easier to reuse code between structures.
For now BVH was converted in C++ and moved to this module
