resolutions to render, to a "start resolution" which gives the resolution
to start at.
This avoids unnecessary rendering of small resolutions in small viewports,
and avoids long waiting on big viewports.
The sampled color ramp data is passed to OSL as a color array. This has to be done as actual float[3] array though, since the Cycles float3 type actually contains 4 floats, leading to shifting color components in the array.
Additional parameter set functions for arrays have been added to the Cycles OSL interface for this purpose.
* Fix Musgrave Texture, used wrong Perlin Noise (0..1) instead of -1..1. Also added comment to noise_basis() to make it clear which noise type is used there.
This commit integrates support of OpenColorIO library into build systems.
It also contains C-API for OpenColorIO library which could be used by Blender.
CMake has got find rules familiar to OpenImageIO's one which makes it easier
for build system to find needed libraries and includes. Scons only could use
explicitly defined paths to libraries and includes.
C-API would be compiled and Blender would be linked against C-API and OpenColorIO
but it wouldn't affect on Blender behavior at all.
OpenColorIO could be disabled by setting up WITH_OCIO to Off in CMake and
setting WITH_BF_OCIO in Scons.
* std::particle_index
* std::particle_age
* std::particle_lifetime
* std::particle_location
* std::particle_size
* std::particle_velocity
* std::particle_angular_velocity
Just as with SVM the rotation state attribute is currently disabled due to lack of a proper quaternion or matrix type in Cycles nodes.
* std::object_location
* std::object_index
* std::material_index
* std::object_random
Other object-based attributes can be added for particle info in the same way.
* Non-Progressive UI couldn't be displayed if the device was set to GPU, but User Preferences Device was NULL. (for example when opening .blend file on another computer without GPU capabilities)
* Fix missing update in the Properties editor, when changing compute_device.
This fixes [#32115] OSX and cycles no non-progessive sample input settings appearing in interface.
When the scene is updated Cycles resets the renderer device, cancelling
all existing tasks. The main thread would wait for all running tasks to
finish before continuing. This is ok when tasks can actually cancel in a
timely fashion. For OSL however, this does not work, since the OSL
shader group optimization takes quite a bit of time and can not be
easily be cancelled once running (on my crappy machine in full debug
mode: ~0.12 seconds for simple node trees). This would lead to very
laggy UI behavior and make it difficult to accurately control elements
such as sliders.
This patch removes the wait condition from the device->task_cancel
method. Instead it just sets the do_cancel flag and returns. To avoid
backlog in the task pool of the device it will return early from the
BlenderSession::sync function while the reset is going on (tested in
Session::resetting). Once all existing tasks have finished the do_cancel
flag is finally cleared again (checked in TaskPool::num_decrease).
Care has to be taken to avoid race conditions on the do_cancel flag,
since it can now be modified outside the TaskPool::cancel function
itself. For this purpose the scope of the TaskPool::num_mutex locks has
been extended, in most cases the mutex is now locked by the TaskPool
itself before calling TaskScheduler methods, instead of only locking
inside the num_increase/num_decrease functions themselves. The only
occurrence of a lock outside of the TaskPool methods is in
TaskScheduler::thread_run.
This patch is most useful in combination with the OSL renderer mode, so
it can probably wait until after the 2.64 release. SVM tasks tend to be
cancelled quickly, so the effect is less noticeable.
Instead of including util_string.h which in fact also defines some
symbols from util_string.cpp include STL's string header and directly
use std::string.
* reverted r50430
* removed 2 util_params.h includes from r50428, these were causing trouble with OIIO in CUDA compilation. The purpose of these was to define the ustring type, but can just use the standard string type from util_string as well.
* Added the Phong BRDF from the inbuilt OSL shader library.
This can be used in OSL shaders only for now:
* phong(normal N, float exponent)
* phong_ramp(normal N, float exponent, color colors[8]
