* Adding hue instead of removing it.
fmod doesn't work as % when it comes to negative numbers:
fmod( 1.3, 1) == 1.3 % 1 == 0.3
fmod(-0.3, 1) != -0.3 % 1

This fixes a brief flash of random data on Blender startup on my
system (Ubuntu 11.10, ATI Mobility Radeon HD 5650, Gallium drivers.)

* Added some new integrator parameters to the xml reading.
* Added ability to specify window width/height, if not set it uses film/camera width/height.
* Added back the xml exporter script from cycles branch, with modifications to hock up into the UI. To use it, copy the script into 2.61/scripts/startup.
Note: This is intended for developers for now, but the standalone Cycles app has potential to be used as benchmark for example.
- rename 'bcycles' --> '_cycles', since this is the python convention when a py module uses a C module internally.
- use macros for returning None
- make with_osl an attribute rather then a function.
- changes methods METH_VARARGS --> METH_O when single args are used.
This allows group nodes inside other group nodes in cycles and makes the
code more generic for all possible cases, like direct group
input-to-output links and unused group sockets.
Previous code tried to connect external nodes and internal group sockets
by following links until a "real" node input/output. This quickly
becomes complicated in corner cases as described above and can lead to
unexpected behavior when the group socket is of a different type than
the internal/external sockets, but that conversion is skipped.
The new code uses the concept of "proxy nodes" similar to what the new
compositor does. Each group socket is replaced with a proxy node with a
single input and output, to which other nodes in the same tree and
internal nodes can link to. After all groups have been expanded in the
graph, these proxy nodes are removed again, adding converter nodes if
necessary.
Node specially useful for Texture correction.
This is also a nice example of a simple node made from scratch in case someone wants to create their custom nodes.

Note: dot is reversed compared to Blender.
In Blender Normals point outside, while in Cycles they point inside.
If you use your own custom vector with the Normal Node you will see a difference.
If you feed it with object normals it should work just as good.
lower than 1.3, since we're not officially supporting these. We're already not
providing CUDA binaries for these, so better make it clear when compiling from
source too.
* Added option "WITH_BF_CYCLES_CUDA_THREADED_COMPILE" for the people who have much RAM (8 or more) and can compile several kernels at the same time. If enabled, it uses the general BF_NUMJOBS flag.
* The option is off per default.
Fix#29475: remove node from properties editor crash on windows. This was a bug
in the UI code, which code access removed data.
Fix OpenCL still being used in a case where Experimental was disabled.
Fix msvc debug warning in md5 code.
as with the HSV node the OSL code is relying on the (yet to be implemented) autorename.
Also the svm code could use mix (svm_lerp) instead:
32 . float3 color_inv = make_float3(1.0f, 1.0f, 1.0f) - color;
35 . . stack_store_float3(stack, out_color, svm_lerp(color_inv, color, factor));
I have a feeling that each node 'program' should have the least program as possible. I'll see with Brecht later.
But overall I don't know if that's any fast. And apart from that I think we will need this kind of function to move to a library if multiple functions linked in are not a problem.

Important note:
the camera Z is reverted compared to Blender render.
Now it goes from zero (camera) to positive (in front of the camera)
.........................
note, the OSL code has a problem.
In the original node the input and output nodes have the same name (Color).
So this will be fixed here once Brecht come up with a nice autorenaming (or we do a doversion patch) for that.
Array indexing doesn't work there.
I'm yet to setup my CUDA computer, in the meantime this proved to work (tested by Daniel Salazar).
If I found other ways of doing it I get back to that.
* Compile all of cycles with -ffast-math again
* Add scons compilation of cuda binaries, tested on mac/linux.
* Add UI option for supported/experimental features, to make it
more clear what is supported, opencl/subdivision is experimental.
* Remove cycles xml exporter, was just for testing.
bit so that it's more symmetric and resulting float ops are compiled the same
way. Otherwise extended float precision being used in one place and not the
other can make comparisons fail.
"The Blender Foundation also sells licenses for use in proprietary software under the Blender Licens"
also remove NaN references from files that have been added since blender went opensource.
This change adds RNA access to tesselated face UVs and colors (MTFACE and MCOL), primarily for use by plugin renderers (e.g. cycles). The RNA mesh properties to get to these are prefixed with "tessface_" and additionally the help text states that these are for renderers, to try not to confuse existing mesh editing tool scripts into thinking they could just start using these values.
by Gaia Clary.
Rationale: the name was confusing and not always used consistently, and this
map itself is not something that can be layered, rather the map can be used
as texture coordinates in some layered setup.
The original intent was to indicate this contained more than just UV's, but
the game engine settings have already been moved out, and apparently users
didn't really get this from the name anyway.
Some drivers don't support passing include paths with spaces in them, nor does
the opencl spec specify anything about how to quote/escape such paths, so for
now we just resolved #includes ourselves. Alternative would have been to use c
preprocessor, but this also resolves all #ifdefs, which we do not want.
* Reduce kernel arguments size, helps compile for apple nvidia.
* Fix use of unitialized variable in displace kernel.
* Use build flags in opencl kernel md5 hash.
* Reorganize code for kernel feature #defines a bit.
* Fix#29354: crash on branch file. Note that for best compatibility, you need
to save your files with one of the latest branch builds, since not all version
patching code was moved to trunk.
* Rename "Cycles" to "Cycles Render" in info header menu.
* Code tweaks to try to fix#29301. It's not a real solution though, I'm thinking
cause is extended precision for floats on some cpu's, used in one case but not
in the other, leading to bounding box intersection issue...
* Fix#29257: nan-pixels with zero roughness for glass/glossy.
* Fix#29239: crash with border rendering, this is not working yet, but should
no longer crash now.
* Show object name in 3d view rendered draw type.
* Attempt to improve Sample as Light option description.
* Enable OpenCL Full Shading on NVIDIA cards.
Notes:
It makes not much sense to use OpenCL on a nVidia card (as it is slower compared to CUDA), but as OpenCL comes without dependencies, it's an good alternative if you don't want to install the CUDA toolkit or the build comes without CUDA kernels.
* Fix excessive fireflies in Velvet BSDF (patch by David).
* Disable some unused SSE code
* Remove RTTI disabling flags for now, this is giving some compile issues and
was only needed of OSL which we're not using yet.
* Add back option to bundle CUDA kernel binaries with builds.
* Disable runtime CUDA kernel compilation on Windows, couldn't get this working,
since it seems to depend on visual studio being installed, even though for
this particular case it shouldn't be needed. CMake only at the moment.
* Runtime compilation on linux/mac should now work if nvcc is not installed in
the default location, but available in PATH.
Regarding merge status, there should be no build failures, but cycles may not
be enabled in your build, we are still solving:
* Windows: CUDA kernel compile at runtime is failing, probably will have to
do precompiled kernel again.
* Mac: scons is not building cycles yet.
* Linux doesn't have boost + openimageio libs available in lib/ yet, so it
requires manual install of those libs still.
The __imp__ prefix on glew lib linking errors should have been a good indication: the code was looking for the glew dll.
Bypassed by adding GLEW_STATIC to the definitions.
* It seems we have a problem compiling the CUDA kernel at runtime on Windows,
will need to investigate more how to solve this best, CPU render should go
fine though.
* Change OPENIMAGEIO to OPENIMAGEIO_ROOT_DIR on linux for consistency.
* Disable precompiled cuda binaries, always do at run time
* Change preview samples default to 10
* Hide volume panels since they don't do anything yet
using them, but rather do it now that I have the chance still. Highlights:
* Wood and Marble merged into a single Wave texture
* Clouds + Distorted Noise merged into new Noise node
* Blend renamed to Gradient
* Stucci removed, was mostly useful for old bump
* Noise removed, will come back later, didn't actually work yet
* Depth setting is now Detail socket, which accepts float values
* Scale socket instead of Size socket

to reduce the amount of nodes needed to set up a simple texture.
These are currently editable in the texture properties tab, still need to make
them available in the node editor. Projection and color modification options will
be added later, they're not implemented yet but allocated already to avoid
version patches later.
Also an issue with the XYZ mapping is that when you set one to None, texture and
material draw mode doesn't draw the image texture well, OpenGL doesn't seem to
like the degenerate texture matrix?
* Fluid compilation: Inverse the compile flag from DISABLE_ELBEEM to WITH_MOD_FLUID for consistency. (scons/cmake)
* Use WITH_BF_FLUID in your user config (scons)
* Add support for scons to disable build with Decimate and Boolean modifier.
(WITH_BF_DECIMATE and WITH_BF_BOOLEAN)
- Upgrade Eigen2 library to Eigen3
- Upgrade colamd library and placed in extern/ so other libraries from extern/ can use it
NOTE: With previous version of Eigen (3.0.1) it was necessary to define
EIGEN_DONT_ALIGN_STATICALLY macro to make it compilable on windows 32bit.
After latest upgrade it seems to be unnecessary (at least when was testing libmv),
so i removed that defines which can reduce speed and lead to other problems.
I still think utf8_buf can be 5 (4 bytes + '\0'), but even 6 may not be enough to what is coming next (NFC - precomposedStringWithCanonicalMapping)
incorporating ascii as a subset of utf8. I don't think we need to re-encode it.
U+0000 ~ U+00FF - latin1 set
This bug is also present in Windows, so I believe the real bug is in Linux (and in the text object input).
Also Cmd+C and Cmd+v doesn't work for utf8 yet.
- currently X11 only, depends on Xinput (but should not break other os's).
- ghost stores utf8 buffer, copies to wmEvent's
- UI text input is currently the only area that uses this - not console or text editor.
- no rna access yet.
* Sun, area and point lights with size now supported
* Cast shadow option to disable shadow casting for lamps
* Emission strength of materials tweaked such that setting strength to 1.0
basically makes the material "shadeless" in that the value of the color
input will be the resulting color in the image.
