With small tiles, the repeated allocations on GPUs can actually slow down the denoising quite a lot.
Allocating the buffer just once reduces rendertime for the default cube with 16x16 tiles and denoising on a mobile 1050 from 22.7sec to 14.0sec.

I wouldn't mind changing style to have space after keyword, but there was
no official code style change proposed.

Was only happening for release builds made with GCC-8. Probably some
optimization strtegy was confused by uninitialized variable.

Building the CUDA kernels takes quite a bit of memory, and when building all of
them the combined usage can be too much on some systems (especially VMs).
Therefore, this patch adds an option to force the build system to build them
sequentially by making each build step depend on the previous kernel.

The half float extension is not supported on macOS, rather it's simply
part of OpenGL core so we don't need to check.

This replaces old single toggle option to subdivide UVs with
an enum which can have more options. The usecase for this is
to be compatible with other software. But we also might choose
different subdivision type as default in the future.
DNA and underlying code supports all possible options, but
only the ones which are compatible with old subdivision code
are currently exposes.

C-API is way smaller than the rest of the code which uses it.
So better to conditionally compile stub implementation than
to keep adding ifdef everywhere.

Makes it more clear whether compute device is Vega 56 or Vega 64.

Currently unused, but will allow to convert unknown
argument type to a string for reporting and such.

Enabled infinite sharp patches for topology refiner and evaluator,
which allows to have sharp edge at first subdivision level.
Also tweaked crease export from Blender to OpenSubdiv to have more
artistic control over the whole 0..1 range.

Before that it was only first UV layer which was properly evaluated,
the rest were ignored. Now all layers are being properly handled.
|
|
Currently unused, added for the future and API completeness.

The idea is simple: do not provide full topology to OpenSubdiv, leave
edges creation to OpenSubdiv itself. This solves issues with non-manifold
meshes which were known to fail, including the ones from T52059.
On a positive side we can simplify our side of converter, keeping code
shorter.
it is still possible that we'll need to ensure all loops has same
winding, but that is less things to worry about.
|
|
Seems it's behaving correct now, surely more tests needed, but
this is required for now to move forward.

Applies to vertices and edges. Biggest annoyance here is that OpenSubdiv's
topology converter expects that there is no loose geometry, otherwise it
is getting confused.
For now solution is to create some sort of mapping from real Mesh vertex
and edge index to a non-loose-index. Now the annoying part is that this
is an extra step to calculate before we can compare topology, meaning FPS
will not be as great as if we knew for sure that topology didn't change.
Loose edges subdivision is different from what it used to be with old
subdivision code, but probably nice feature now is that endpoints of loose
edges are stay at the coarse vertex locations. This allows to have things
like plane with hair strands, without need to duplicate edge vertices at
endpoints.
All this required some re-work of topology refiner creation, which is now
only passing edges and vertices which are adjacent to face. This is how
topology refiner is supposed to be used, and this is how its validator
also works. Vertices which are adjacent to loose edges are marked as
infinite sharp. This seems to be good-enough approximation for now. In the
future we might tweaks things a bit and push such vertices in average
direction of loose edges, to match old subdivision code closer.

This commit merge the full development done in greasepencil-object branch and include mainly the following features.
- New grease pencil object.
- New drawing engine.
- New grease pencil modes Draw/Sculpt/Edit and Weight Paint.
- New brushes for grease pencil.
- New modifiers for grease pencil.
- New shaders FX.
- New material system (replace old palettes and colors).
- Split of annotations (old grease pencil) and new grease pencil object.
- UI adapted to blender 2.8.
You can get more info here:
https://code.blender.org/2017/12/drawing-2d-animation-in-blender-2-8/
https://code.blender.org/2018/07/grease-pencil-status-update/
This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible.
Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.

This is in preparation of upgrading our library dependencies, some of which
need C++11. We already use C++11 in blender2.8 and for Windows and macOS, so
this just affects Linux.
On many distributions this will not require any changes, on some
install_deps.sh will need to be run again to rebuild libraries.

Patch by Stefan, with minor tweaks by Brecht.

Just basic algebra - because all vectors have the same z coordinate, a lot of terms end up cancelling out.
Not exactly a massive improvement, but it's measurable with Branched PT and a high sample count on the lamp.
