Callers now have to use Gawain's COMP enum to specify vertex attributes.
This makes the API more bullet-proof (at least less vulnerable) since GLenum covers waaay more than component types.
Also prepares us for Vulkan.
|
|
Quads are not part of modern GL or Vulkan, so we should avoid them. XXX makes coders think "hmm how could I draw this without using quads?"
Quads will be removed during the transition to core profile.

Was confusing guarded allocator for some reason.

The state mask wasnt applied before comparison giving false results. It
shouldnt really happen that a ray state contains any flags that need to
be masked away, but if it does happen its better to not get stuck.

See intern/gawain for the API change. Other files are updated to use the new name. Also updated every call site to the recommended style:
unsigned int foo = VertexFormat_add_attrib(format, "foo", COMP_ ... )

Mainly visible for MSVC debug builds and gives about 2x speedup.

This avoids write access happening in non-atomic manner in
Shader::tag_update which modifies the global managers. Even
for 1 byte data types it's quite dangerous.
|
|
The issue is coming from the fact that float3 is actually 16 bytes aligned
data type and the "padding" was not initialized. This caused memcmp() to
access non-initialized memory.

Update tag might access links (when checking for attributes) and
the links might be in the middle of rebuild in simplification
logic.

Reported by Mai in IRC, thanks!

The issue was apparently caused by -fno-finite-math-only added to kernel.cpp
CFLAGS. For now just removed this flag from the kernel (we don't really want
it there at this point, and we don't have it for SSE/AVX optimized kernels).
But surely more investigation is needed here.

Makes it more explicit what the structure is from it's name.

This deprecates CUDA 7.5.

The idea is to make include statements more explicit and obvious where the
file is coming from, additionally reducing chance of wrong header being
picked up.
For example, it was not obvious whether bvh.h was refferring to builder
or traversal, whenter node.h is a generic graph node or a shader node
and cases like that.
Surely this might look obvious for the active developers, but after some
time of not touching the code it becomes less obvious where file is coming
from.
This was briefly mentioned in T50824 and seems @brecht is fine with such
explicitness, but need to agree with all active developers before committing
this.
Please note that this patch is lacking changes related on GPU/OpenCL
support. This will be solved if/when we all agree this is a good idea to move
forward.

The intention of this commit it to address issues mentioned in the
reports T43865,T50164 and T50452.
The code is based on Embree code with some extra vectorization
to speed up single ray to single triangle intersection.
Unfortunately, such a fix is not coming for free. There is some
slowdown for AVX2 processors, mainly due to different vectorization
code, which caused different number of instructions to be executed
and different instructions-per-cycle counters. But on another hand
this commit makes pre-AVX2 platforms such as AVX and SSE4.1 a bit
faster. The prerformance goes as following:
2.78c AVX2 2.78c AVX Patch AVX2 Patch AVX
BMW 05:21.09 06:05.34 05:32.97 (+3.5%) 05:34.97 (-8.5%)
Classroom 16:55.36 18:24.51 17:10.41 (+1.4%) 17:15.87 (-6.3%)
Fishy Cat 08:08.49 08:36.26 08:09.19 (+0.2%) 08:12.25 (-4.7%
Koro 11:22.54 11:45.24 11:13.25 (-1.5%) 11:43.81 (-0.3%)
Barcelone 14:18.32 16:09.46 14:15.20 (-0.4%) 14:25.15 (-10.8%)
On GPU the performance is about 1.5-2% slower in my tests on GTX1080
but afraid we can't do much as a part of this chaneg here and
consider it a price to pay for more proper intersection check.
Made in collaboration with Maxym Dmytrychenko, big thanks to him!

This primitive is used in geometry shaders like new grease pencil stroke shaders

Since 2.5x we should try to avoid such abreviations in the UI, except for common terms like Min / Max as much as possible.
|
|
Previously it was beneath the Performance UI label, which was incorrect. It's better suited next to Ray Visibility.
