PRESENT is an exclusive flag in NXT and can't be combined with other flags. The existing implementation treats the D3D12_RESOURCE_STATE_PRESENT as flag which is confusing due to being 0.
The Swapchain::Configure was changed to not require an initial usage
anymore. Previously the code was doing a transition to this usage
causing the code to now transition to <uninitialized data> usage.
Fix this by deleting code. Also make TextureD3D12 responsible for the
transition to PRESENT.
Making all textures represented by pointers is a problem for Vulkan
where VkImage is a 64bit type and wouldn't fit in a pointer on 32bit
builds. Make texture contain on of each useful type so that each backend
can choose which one it wants to receive.
There was a lot of missing around with viewports and flip the Y
coordinate in vertex shaders before. Turns out things are simpler than
we thought: *all* APIs have gl_Position(-1, -1) map to texel (0, 0). It
is just the present coordinate system that changes.
Remove some of the hacks we had to work around non-existent viewport
issues and fix tests.
This as this is the first command handled by the Vulkan backend, this
commit also introduces the b:✌️:CommandBUffer class and implements
b:✌️:Queue::Submit.
Also enables the BufferSetSubData tests that are now passing on Vulkan
even though the buffer transitions are unimplemented.
This was because the clip space of OpenGL has an inverted Y compared to
other APIs. This commit:
- Updates SPIRV-Cross to the latest version
- Uses the new vertex.flip_vert_y option in ShaderModuleGL
- Enables tests that are now passing in GL.
Previously didn't tell SPIRV-Cross at which MSL resource indices the
different SPIRV binding should be, and were lucky that it's giving
indices in increasing order matched the PipelineLayout in all our
samples.
Fix this by making SPIRV->MSL compilation depend on the PipelineLayout
so we can tell SPIRV-Cross which binding goes where.
We should do the same for vertex attributes eventually as they are
hardcoded to start at kMaxBindingsPerGroup currently.
Also a couple unrelated cleanups (unused function, usage of
IterateBitSet).
Adds the swap chain interfaces to the API without changing the behavior
of anything else. This includes the C APIs for applications to provide
swap chain implementations. Also adds stub implementations on every
backend.
