Previous fix wasn't working correct for certain compiler and CPU intrinsics
mode, causing quite some crashes.
This should be a safer fix, which is closer in behavior to previous release
but which should still fix issues with robust curve intersection.

Audio mixing is done with volume interpolation. A new handle started at
volume 1, now starting at volume 0 for a smooth fade in.
|
|
If a pixel has negative components, something already went wrong, so the best option is to just ignore it.
Should be good for 2.79.

Would be nice to be able to catch this with assert as well, will see what would
be the best way to do this/.\
Need to verify with Mai that this solves crash for her and maybe consider
porting this to 2.79.

We need to make sure we can store all volume closures for all objects in volume
stack. This is a bit tricky to detect what would be the "nestness" level of
volumes so for now use maximum possible stack depth. Might cause some slowdown,
but better to give reliable render output than to fail quickly.
Should be safe for 2.79 after extra eyes.

Basically, make re-alloc and memcpy from the same lock, otherwise one
thread might be re-allocating thread while another one is trying to
copy data there.
Reported by Mohamed Sakr in IRC, thanks!

Generalizes current conditions, QT implements it the same way.

The order of evaluation of function arguments is undefined, and the order
was reversed between these compilers. This was causing regressions tests
to give different results between Linux and macOS.
|
|
|
|
This was causing different render results with different compilers. We
can't do much useful with 1 sample, but better for debugging.

GCC seems to detect uninitialized into function calls now, but then isn't
always smart enough to see that it is actually initialized. Disabling this
warning entirely seems a bit too much, so initialize a bit more now.

GPUs together
This commit unifies the flattened texture slot names for bindless and regular CUDA textures. Texture indices are now identical across all CUDA architectures, where before Fermi used different indices, which lead to problems when rendering on multi-GPU setups mixing Fermi with newer hardware.

Change the implementation so it no longer takes over the mouse cursor motion
from the OS, instead only move it when warping, similar to Windows and X11.
Probably the reason it was not done this way originally is that you then get
a 500ms delay after warping, but we can use a trick to avoid that and get much
smoother mouse motion than before.

transparent object
Tweaked the path radiance summing and alpha to accommodate for possible contribution of
light by transparent surface bounces happening prior to shadow catcher intersection.
This commit will change the way how shadow catcher results looks when was behind semi
transparent object, but the old result seemed to be fully wrong: there were big artifacts
when alpha-overing the result on some actual footage.
|
|
In branched path tracing main loop is always a camera ray, with varying
number of transparent bounces.

This gives speed up for the split kernel in scenes using the principled BSDF
but without subsurface scattering.

Could have lead to black pixels.

This is something which was reported to work fine by Mai, Benjamin and
confirmed by myself. Disabling this workaround gains us some speedup:

Unfortunately this means disabling the code that ensures the title
bar is properly scaled with DPI, however better to have that as a
cosmetic issue than Blender being unusable with a lot of Intel GPUs.

This file uses std::ostream for helper << operators, so need to make sure
corresponding header is included.

Some of the functions might have been inlined, but others i don't see
how that was possible (don't think virtual functions can be inlined here).
In any case, better be explicitly optimal in the code.

panoramic camera settings
The problem here was that when a "invalid" path is generated by the panoramic camera, it was tagged
as RAY_TO_REGENERATE with the intention of generating a new path in kernel_buffer_update.
However, since that state was not handled in kernel_queue_enqueue, kernel_buffer_update did not
process the path which resulted in an infinite loop.
