Only fixes compilation error, the functionality will be limited.
Currently we don't care that much, since all the work is done in
the branch anyway.
Later on when we'll know which fixes we need to apply on top of
latest OpenSubdiv library we will call a library upgrade.
Main goal is to make API simpler to follow (at least ion terms what
is defined/declared where, as opposite of handful big headers which
includes all the declarations), and also avoid a big set of long and
obscure functions.
Now C-API files are split into smaller ones, following OpenSubdiv
behavior more closely, and also function pointers in structures
used a lot more, which shortens functions names,
UV integration part in GL Mesh is mainly stripped away, it needs
to be done differently. On a related topic, UV coordinates API in
converter needs to be removed as well, we do not need coordinates,
only island connectivity information there.
Additional changes:
- Varying interpolation in evaluator API are temporarily disabled,
need to extend API somewhere (probably, evaluator's API) to inform
layout information of vertex data (whether it contains varying
data, width, stride and such).
- Evaluator now can interpolate face-varying data.
Only works for adaptive refiner, since some issues in OpenSubdiv
itself.
Planned changes:
- Remove uv coordinates from TopologyConverter.
- Support evaluation of patches (as opposite to individual coordinates
as it happens currently).
- Support more flexible layout of varying and face-varying data.
It is stupid to assume varying is 3 floats and face-varying 2 floats.
- Support of second order derivatives.
- Everything else what i'm missing in this list.
- Made OpenSubdiv_GLMesh private
Previously, it was still accessible via C-API from C++ code.
- Don't implicitly refine evaluator when updating coarse positions,
now there is an explicit call to do this.
Allows to first apply all changes to the coarse mesh and then
refine once.
- Added coarse positions update from a continuous buffer with given
starts offset and stride.
Allows to update coarse positions directly from MVert array.
- Refiner is no longer freed when CPU evaluator is created.
Allows to re-use refiner for multiple purposes.
This brings separate initialization for libcuda and libnvrtc, which
fixes Cycles nvrtc compilation not working on build machines without
CUDA hardware available.

We only keep this as a way to get GPU_stubs to run, in case we want to do a
throughout cleanup in the codebase and want code using legacy calls to
fail to build.
This removes glGetBooleanv queries for GL_LIGHTING. This has been #ifdef'd
out with legacy opengl disabled. Thus a false positive still shows up in
the gl queries. Also, note that this removes support for wireframes in
opensubdiv, when desabling legacy opengl, which should be fixed later.
Part of T49043
The existing code uses the input value count of the first channel
for all of them. If the first channel is the largest, it leads to
a crash-causing buffer overrun in memcpy below. Likely this was
left since the time when only one channel was supported.
As a crash fix, probably should go into 2.78
It became rather annoying to have those functions duplicated.
Surely, it's not really nice it's actually a bad level call,
but similar thing is happening in OCIO and Cycles.
IMO, it's better than having functions re-implemented, and
have this solved with new OpenGL pipeline.
Mainly the changes are related on establishing API to feed UV islands
to OpenSubdiv, so it will know all the connectivity information and
will be able to do proper interpolation.
Island calculation is currently rather slow, not sure how to make it
fast and not use lots of allocations.
Shouldn't be THAT bad, since this code is only runs once when creating
OSD mesh, and it's probably still faster than our orientation code.
A bit work in progress, currently the following limitations:
- Texture shading only, Material shading will come later
- No UVs subdivision yet
- Always uses active UV and currently changing active UV will
not properly update the viewport.
Well, need to start somewhere :)
This probably makes code somewhat slower, but we can't easily know
whether we can use a shortcut and only use directional lighting from
the scene.
Need some better integration between GPU and OpenSubdiv for that.
Seems i was the only one who was really up to using it and
i do have gcc-5 finally backported and installed here so
such a fine-tune flags are no longer needed.
While SCons building system was serving us really good for ages it's no longer
having much attention by the developers and started to become quite a difficult
task to maintain.
What's even worse -- there started to be quite serious divergence between SCons
and CMake which was only accumulating over the releases now. The fact that none
of the active developers are really using SCons and that our main studio is also
using CMake spotting bugs in the SCons builds became quite a difficult task and
we aren't always spotting them in time.
Meanwhile CMake became really mature building system which is available on every
platform we support and arguably it's also easier and more robust to use.
This commit includes:
- Removal of actual SCons building system
- Removal of SCons git submodule
- Removal of documentation which is stored in the sources and covers SCons
- Tweaks to the buildbot master to stop using SCons submodule
(this change requires deploying to the server)
- Tweaks to the install dependencies script to skip installing or mentioning
SCons building system
- Tweaks to various helper scripts to avoid mention of SCons folders/files
as well
