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.

Accessed custom-data layer offset before creating.

Also de-duplicate poll functions

Useful for batch conversion and tests.

Newer toolkit has some weird issue with cross0-compiling 32bit kernels
from 64bit environment.
|
|
This was initially needed for heterogeneous setup of two toolkits which
we no longer need.
|
|
This was removed in 93426cb. Please be more accurate when
changing interface.

Calling `SomeClass.draw(self, context)` instead of `self.draw()`
would try to wrap the argument `self` multiple times, causing an error.
|
|
Re-registering an operator used by the keymap would lead memory.
Reload scripts for eg leaked over ~1600 blocks.
|
|
Needed since templates may unregister classes.
Also replace old modules on reloading.

This allows the props to extend into the blank space that is to the right.

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!

That one was:
* Resetting non-ID pointers (lib_link_xxx funcs should only affect ID
pointers, everything else shall be done in direct_link_xxx func).
* Even worse, always calling lib_link_animdata, even when
LIB_TAG_NEED_LINK tag was unset...
|
|
We do not need any special handling anymore for usercount of images used
by faces/polygons (tpage stuff), since we have the 'real_user' handling,
which will gracefully cope with all possible situations.
So better not keep that ugly confusing useless special case.
|
|
Mainly:
* Add missing `IDP_LibLinkProperty()` calls for many ID types
(harmless currently, but better be consistent here!).
* Bring lib_link_xxx functions more in line with each other.
* Replace some long if/else by switch.

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.

Solves majority of speed regression on AMD OpenCL.

The title says it all actually.

Simplifies code quite a bit, making it shorter and easier to extend.
Currently no functional changes for users, but is required for the
upcoming work of shadow catcher support with OpenCL.
|
|
It uses an idea of accumulating all possible light reachable across the
light path (without taking shadow blocked into account) and accumulating
total shaded light across the path. Dividing second figure by first one
seems to be giving good estimate of the shadow.
In fact, to my knowledge, it's something really similar to what is
happening in the denoising branch, so we are aligned here which is good.
The workflow is following:
- Create an object which matches real-life object on which shadow is
to be catched.
- Create approximate similar material on that object.
This is needed to make indirect light properly affecting CG objects
in the scene.
- Mark object as Shadow Catcher in the Object properties.
Ideally, after doing that it will be possible to render the image and
simply alpha-over it on top of real footage.

noninteractive rendering
Before, Cycles would first sync the shader exactly as shown in the UI, then determine and sync the used attributes and later optimize the shader.
Therefore, even completely unconnected nodes would cause unneccessary attributes to be synced.
The reason for this is to avoid frequent resyncs when editing shaders interactively, but it can still be avoided for noninteractive renders - which is what this commit does.

Allow auto-execution to be enabled,
also move this to user-prefs versioning code.
