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.
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.
* 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 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.
* 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
http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Textures
* Passes renamed to samples
* Camera lens radius renamed to aperature size/blades/rotation
* Glass and fresnel nodes input is now index of refraction
* Glossy and velvet fresnel socket removed
* Mix/add closure node renamed to mix/add shader node
* Blend weight node added for shader mixing weights
There is some version patching code for reading existing files, but it's not
perfect, so shaders may work a bit different.
* Fix missing update when editing objects with emission materials.
* Fix preview pass rendering set to 1 not showing full resolution.
* Fix CUDA runtime compiling failing due to missing cache directory.
* Use settings from first render layer for visibility and material override.
And a bunch of incomplete and still disabled code mostly related to closure
sampling.
* OpenCL now only uses GPU/Accelerator devices, it's only confusing if CPU
device is used, easy to enable in the code for debugging.
* OpenCL kernel binaries are now cached for faster startup after the first
time compiling.
* CUDA kernels can now be compiled and cached at runtime if the CUDA toolkit
is installed. This means that even if the build does not have CUDA enabled,
it's still possible to use it as long as you install the toolkit.
* Compute MD5 hash to deal with nvidia opencl compiler cache not recognizing
changes in #included files, makes it possible to do kernel compile only
once and remember it for the next time blender is started.
* Kernel tweak to compile with ATI/linux. Enabling any more functionality than
simple clay render still chokes the compiler though, without a specific error
message ..
* Fix crash in light path node
* Fix struct alignment issue for cuda
* Fix issue with instances taking up too much memory
* Fix issue with ray visibility working incorrect on some objects
* Enable OpenCL always and remove option, it has no dependencies so may as well
* Refuse to load kernel if OpenCL version < 1.1, recent drivers are needed
* Better error handling for OpenCL device
* 3D views with rendered draw mode will now revert to wireframe on file load
* Add alpha pass output, to use set Transparent option in Film panel.
* Add Holdout closure (OSL terminology), this is like the Sky option in the
internal renderer, objects with this closure show the background / zero
alpha.
* Add option to use Gaussian instead of Box pixel filter in the UI.
* Remove camera response curves for now, they don't really belong here in
the pipeline, should be moved to compositor.
* Output full float values for rendering now, previously was only byte precision.
* Add a patch from Thomas to get a preview passes option, but still disabled
because it isn't quite working right yet.
* CUDA: don't compile shader graph evaluation inline.
* Convert tabs to spaces in python files.
* add some (disabled) test code for using OpenImageIO in imbuf
* link cycles, openimageio and boost into blender instead of a shared library
* some cmakefile changes to simplify the code and follow conventions better
* this may solve running cycles problems on windows XP, or give a different
and hopefully more useful error message
