Fallback to use the embedded compiled shader if the source shader fails to compile
Only try to get pixel history DXIL shaders for captures that use DXIL
* Previously MRT draws were reduced to a single RT with the pixel
history color target bound, which meant shader output was always
showing the results for RT0 rather than the target requested.
* Shader-out and post-mod passes of the per fragment callback have been
changed to keep all RTs bound and replace the history target into the
correct slot. The RenderTargetWriteMask is used to mask out all writes
to everything but the history target.
* The pixel history fixed color write shader has been changed to
provide 8 variations, each of which writes to only one of the possible
RTs. This prevents the other targets from being polluted by unintended
writes and fixes the validation warnings about shaders writing to RTs
that will not be bound.
* Unused render target index was removed from the occlusion callback.
* Add missing resource transitions for the dispatch copy to fix
validation issues encountered while running the test.
* Adjust the MSAA copy path to use the second channel for stencil to
fix copies failing to output anything, which manifested as the fragment
only showing one primitive without correct output data.
New 'Exploded' visualisation mode in BufferViewer with new exploder controls
hidden when not in 'Exploded' mode.
Change 'solidShading' and 'solidShadeMode' to 'visualisation' and
'visualisationMode'.
Hide the 'highlightVerts' widget when using 'Exploded' vis for both
real-estate and practical implementation reasons.
Handle depth copying with a texture array source
Clear stencil to zero during the depth copy to match the other implementations
Specify the bind flags when creating the new depth-stencil texture
Support shader exported depth by replaying using the capture pixel shader to determine passing pixels
Don't write depth or stencil during the reply of failing pixels
No need to restore depth-stencil after replay of failing pixels
This adds some of the D3D12 pixel history framework, with creation
of resources that will be needed during pixel history, and a helper
function and shader to copy pixels from MSAA resources.
* When debugging a pixel or doing quad overdraw we replace the pixel shader and
patch in our own UAV. Previously we were moving other UAVs out of the way that
were visible to the pixel shader, but this fails if a UAV is visible to all
stages and used in a vertex stage.
* Now instead for pixel shader inputs we pick a free space and use it. For quad
overdraw we pick an arbitrary high space to hopefully use the precompiled
shader, and if it's somehow not free we recompile the shader with a free
space.
- Blit fragments and read back results in batch
- Modify per fragment callbacks to reduce number of full replays
- Use defines in the primitiveId shader to toggle between float/int
output
- Deleted WriteClearValues and replace with QueryPostModValues
- Add support for earlier GLSL versions and fix logic for creating primitive id program
- Changed to only run per fragment queries on events with multiple fragments
* This distinction unfortunately does not exist in SPIR-V so we have to carry
around this metadata ourselves. Rather than allowing free specification of
tools based on API, instead pretend that Vulkan and GL SPIR-V are separate
format, and duplicate all SPIR-V tools to handle "both" types. This allows
appropriate tool selection based on the encoding.
* This works around an obtuse GL requirement that explicit locations on one side
will cause a break in compatibility with the other side, even if dropping the
location would work otherwise.
* D3D12 math shader was already precompiled, but on D3D11 we now allocate
everything up front and on D3D12 we also up-front compile sampling.
* The only exception is const offsets which can't be variable, so we cache these
(likely we'll only see a few variants per shader/capture) and create them on
demand.
