Weirdly enough, this version of XCode seems to have static_assert()
even when NOT using C++11. This is totally weird and counter intuitive
since static_assert() is supposed to be C++11 onlky feature.
Can XCode stop using future, please? :)

The two SVM nodes added with e7ea1ae78c caused a slowdown on AMD cards when rendering with OpenCL, whether displacement was used or not.
In the Barcelona Pavillon scene on a RX480, this would cause a 12% slowdown.
Therefore, this commit adds a additional flag for feature-adaptive compilation so that the new SVM nodes are only enabled when they are needed (Node tree connected to the Displacement output and Displacement type set to Both).
Also, the nodes were also added to shaders when the Displacement Type was set to Bump (the default), which was unneccessary and is fixed now.
Thanks to linda2 on IRC for reporting and testing and to maiself for help with the displacement shader code.
This fix might be relevant for 2.78, but it should be tested further before including it.

Could not reproduce it here, but since users having the issue claims it comes from
rB16cb9391634dcc50e, let's try to use again ugly `XLookupKeysym()` for those modifier keys too...

keyboards, and with non-first layouts.
This is a tentative fix, own tests here seem to be working OK,
but don't think it's safe enough to be backported to 2.78.

Update on Frame Change
Not really ideal fix at all, but we are at RC today, so better to play really safe.

Object coordinates can now be used in the displacement shader and will give
correct results, where as before bump mapping was calculated from the displace
positions and resulted in incorrect shading.
This works by evaluating the shader in two parts, first bump then surface, and
setting the shader state to match what it would be if the surface was
undisplaced for the bump shader evaluation. Currently only `P` is set as if
undisplaced, but other shader variables could be set as well, such as `I` or
`time`. Since these aren't set to anything meaningful for displacement I left
them out of this patch, we can decide what to do with them separately.

Storing multiple copies of a shader was needed when the displacement method was
a mesh option and could be different for each mesh. Now that its a shader option
this is unnecessary.

Not sure what happened here. Will have only effected Cycles standalone with
linear subdivision in use.

There basically are two issues here: in smooth mode (and all non-tangent
normal map types) it doesn't invert the normal for backfacing polys;
on the other hand for flat shaded tangent type it is inverted too soon.
This fix does a brute force correction by checking the backfacing flag.

Meshes with Cycles subdivision were being transformed to world space leading to
normals to sometimes be calculated in that space, while they should be in
object space. Also caused dicing to happen at the wrong rate for scaled meshes.

Users have been getting a bit confused by the way things are worded/arranged in
the UI. This patch makes a few changes to the UI to make it more clear how to
use subdivision:
- make Subdivide UVs option inactive when adaptive subdivision is enabled as UV
subdivision is currently unsupported
- add "px" to dicing rates in the Geometry Panel
- display the final dicing rate in the modifier
- reworded "Dicing Rate" in the modifier to "Dicing Scale" to make more clear
that this is a multiplier for the scene dicing rate and added a note the the
tooltip pointing the user to that setting in the Geometry Panel

OpenSubdiv doesn't like empty meshes, so we need to be careful not to
subdivide when the mesh is empty.
|

Changes from microdisplacement work broke previous support for subdivision
meshes, sometimes leading to crashes; this makes things work again. Files
that contain "patch" nodes will need to be updated to use meshes instead, as
specifying patches was both inefficient and completely unsupported by the new
subdivision code.

Fixes part of the performance regressions compared to 2.76b, see T49046, T48876.

The if branches were reordered when the original patch was
committed, which broke the implicit non-NULL guarantee on link.
To prevent re-occurrence, add a couple of unit tests.

For best results use the latest 3Dconnexion driver. But latest is only
supported on Mac OS 10.9+. We go all the way back to Mac OS 10.6 so
have to deal with older driver versions.
See the original dlclose line for my faulty assumption. Waiting to
unload the driver later fixes the crash. Newer drivers don’t seem to
have this issue.
Also removed WITH_INPUT_NDOF guards as NDOFManager.h takes care of
this. Follow-up to b10d005 a few days ago.

When WITH_INPUT_NDOF is disabled, 3D mouse handling code is removed
from:
- GHOST (was mostly done, finished the job)
- window manager
- various editors
- RNA
- keymaps
The input tab of user prefs does not show 3D mouse settings. Key map
editor does not show NDOF mappings.
DNA does not change.
On my Mac the compiled binary is 42KB smaller after this change. It
runs fine WITH_INPUT_NDOF on or off.

These latter can cause MSVC debug asserts if the array is empty. With C++11
we'll be able to do this for std::vector later. This hopefully fixes an assert
in the Cycles subdivision code.

Kernels can now be built without patch evaluation when not needed by the
scene (Catmull-Clark subdivision not in use), giving a performance boost
for some devices.
|
|
kernel_textures.h is included in device_opencl.cpp, so we can't check
__KERNEL_OPENCL__ there.
