* Avoid 2 int castings in hair code and fix some comments.
|
|
* Cycles Mix closure could render strange effects, when the user entered a value out of the 0...1 range. This was already clamped for OSL, clamp for SVM as well.

the second time, as for example Intel CPU startup time is 9 seconds.
* Adds an cache for contexts and programs for each platform and device pair,
which also ensure now no two threads try to compile and write the binary cache
file at the same time.
* Change clFinish to clFlush so we don't block until the result is done, instead
it will block at the moment we copy back memory.
* Fix error in Cycles time_sleep implementation, does not affect any active code
though.
* Adds some (disabled) debugging code in the task scheduler.
Patch #35559 by Doug Gale.

Added an option to show backtrace from where
non-freed datablock was allocated from.
To enable this feature, simply enable DEBUG_BACKTRACE
in mallocn.c file and all unfreed datablocks will
be followed up by a backtrace.
Currently works on linux and osx only,
windows support is on TODO.
This feature is for sure disabled by default,
so does not affect any builds which don't
explicitly define DEBUG_BACKTRACE.
|
|
* Move some hair width related code into a dedicated branch.
* Don't calculate time/lens RNG when Motion Blur or Depth of Field are disabled
|
|
also change define checks in BLI_sys_types.h (was warning a lot in linux about unused defines).
|
|
remove MEM_sys_types.h which was a duplicate.
|
|
WM_SIZE is dispatched before full init.
|
|
varibale
already adds an extra step. Also list all features for OpenCL AMD to make testing
easier.

a separate Blender Object/World Space that is compatible with Blender render
baking and uses the YZ flipping convention.
|
|
Now it uses the same (strange) YZ flipping convention.
|
|
* Use advanced shading for nvidia as well, works fine on my Geforce 540M with sm_21.
I tested the files from regression suite.
|
|
* Support using devices from all OpenCL platforms, so that you can use e.g. both
Intel and NVidia OpenCL implementations if you have them installed.
* Fix compile error due to missing fmodf after recent math node change.
* Enable advanced shading for Intel OpenCL.
* CYCLES_OPENCL_DEBUG environment variable for generating debug symbols so you
can debug with gdb. This crashes the compiler with Intel OpenCL on Linux though.
To make this work the preprocessed kernel source code is written out, as gdb
needs this.
* Show OpenCL compiler warnings even if the build succeeded.
* Some small fixes to initialize cdDevice to NULL, add missing NULL check when
creating buffer and add missing space at end of build options for Apple OpenCL.
* Fix crash with multi device + opencl, now e.g. CPU + GPU render should work.
I did a few tweaks to the code and also:
* Fix viewport render failing sometimes with Apple CPU OpenCL, was not taking
workgroup size limits into account properly.
* Add compile error when advanced shading in the Blender binary and OpenCL kernel
are not in sync.
|
|
* Some closures (Toon, Diffuse Ramp) were not assigned to a CLOSURE_IS_* define, which made them invisible on render passes.
* Westin closures had wrong type, Sheen is Diffuse, Backscatter is Glossy.
|
|
* Avoid redundant assignment and use correct Normal for Ray Differentials.
|
|
* Fix a condition in the hair BVH code.
|
|
* Rename fresnel_dielectric() to fresnel_dielectric_cos() to match SVM, easier when searching code.
* Also remove an old code comment in bsdf_reflection.h from Cycles branch days.
|

Removing old resize stuff.
Windows has resize lag, which creates black gap with openGL. Still looking to fix it.
|
|
- Removed grid-snapping for area coordinates on scaling windows.
That caused the areas to shrink or expand, and eventually corrupt screen layouts.
- Added simple but efficient life resize for OSX. I need to know why this is so much
code for Windows... I suggest Windows to just copy same method; dispatch the queue,
and just let the event system draw.
|
|
* Make sure we have valid geometry data, fixes a crash with Lamp objects.
Reported by lichtwerk in IRC, thanks!
|
|
* Added a toon bsdf node to Cycles. This was already available as OSL only closure, but is now available inside the SVM backed as well, for CPU and GPU rendering.
* There are 2 variations available, diffuse and glossy toon, selectable via a menu inside the node.

Thanks to Miika for pointing this issue out and fixing it.

results, as if smoke was colliding in an invisible wall.
This was caused by a "hack" Daniel Genrich introduced in his moving obstacles commit in r46050. I suppose it was originally added to prevent issues with too fast moving obstacles, but now it ended up limiting maximum velocity of higher resolution simulations.
Here is an comparision of 184 resolution simulation (simulation area limited by adaptive domain):
https://www.miikah.org/blender/smoke_with_pressure_limit_hack.png
https://www.miikah.org/blender/smoke_without_pressure_limit_hack.png
I now reverted that hack until a better solution is found. Daniel, can you check this out? Pressure was limited to maximum of dt * dx (= dt / res) which doesn't make sense to limit pressure based on grid resolution. Maybe better to limit with a constant factor instead?

openmp was enabled.
This was a typical threading issue. Move that particular function out of the parallel block.
|
|
* Use M_2PI_F in more places and do multiplication instead of division in gradient texture.
|
|
* Re-use already defined Westin closure class.
|

a different function signature. (which evidently works but error prone).
|
|
include conflicts later on.
|
|
often write protected on modern systems.
This caused high resolution smoke to always regenerate new tile when domain was reinitialized, slowing down especially adaptive domain simulations. Now noise tile is saved in Blender temp directory instead.

* Added a wireframe node (Input category) to get access to Mesh wireframe data.
The thickness can be controlled via a "Size" parameter, and is available in world units (default) and screen pixel size.
* Only the triangulated mesh is available now, quads is for later.

|
* Added a Modulo operation to the math node, available in Compositor, Shader and Texture Nodes.
|
|
* Remove an unused parameter from Checker texture and correct a typo in license header.
|
|
looks to be the cause of bug [#35415]
we can make this optional.
|
|
* Fix OSL compilation for scene_intersect(), when __Hair__ was disabled.
|
|
* Added Westin Sheen and Westin Backscatter closures for testing, useful for Cloth like effects.
Only available via OSL, added an example OSL shader to the Templates (Text Editor).
|
|
* Also do pressure interpolation for brush size and spacing.
* Do smoothing of pressure when smooth stroke and sample average is enabled.
* Revert the OS X specific pressure change to pressure ^ 2.5, for low pressure
values like 0.05 it makes the pressure 100x lower, which is problematic. If
we need to adjust the pressure curve it should be done for all platforms.
Still weak:
* Pressure of first touch on tablet is difficult to control, usually it's low
which makes the stroke start out small or soft, but other times not. Finer
event capturing at ghost level would help, along with pressure changes without
mouse movement, but this may also need different paint stroke logic.
* Brush radius is rounded to integers, this gives noticeable stepping.
* Brush falloff is not antialiased, gives noticeable aliasing for small brush
sizes which was always a problem, but is more common with size pressure control.
|
|
* Simplify shaperadius() function a bit to avoid castings.
* Style cleanup 1.f -> 1.0f, to follow rest of Cycles code.

Blender with default (BI) renderer. To do so, it's defining an "other" texture context, and when in this one, it switches to using the "new shading" texture handling already known with Cycles engine.
So now, in the new "other" tex context, you can (depending on active data) have direct access to modifiers', force's or brushes' textures...
I also refactored a bit how texture contexts are handled (once again, we had some quite similar code in both space_buttons and RNA sources). This should also solve some harmless glitches like "no texture context selected in UI" sometimes when you remove data related to current texture (see e.g. after removing the material from default cube, in startup scene).
This usage of two different systems for textures, and the handling of switches between them, has been a bit tricky to get working right, but it is OK now I think. I also had to add a bool flag to buttons space, SB_TEX_USER_LIMITED (use_limited_texture_context in RNA), which indicates "new shading" texture code whether it has to ignore materials, lamps etc. (BI) or not (Cycles).
Btw, pinned textures from modifiers/force/etc. were also broken (showing nothing), now it should work too.
Thanks to Brecht for reviewing.

* Put render resolution x/y into a function.
|
|
* Avoid one max() call for the bssrdf radius, the if condition already checks for values < BSSRDF_MIN_RADIUS.
|
|
|
|
|
|
* Revert part of r56832, if code gets more complicated, it's better to keep it more logical here.
|
|
* Some simplification of closure code (Velvet and Toon).
|
|
OpenCL fixes.
