This introduces two new methods to `ToneMapper`: `isOneDimensional()` and
`isLDR()`. `ColorGrading` references these values along with other parameters
passed to the builder to determine if we can get away with only generating a
one-dimensional LUT. Meanwhile, `PostProcessManager` takes care of setting the
new spec constants and uniforms for `colorGrading.mat` and
`colorGradingAsSubpass.mat`.
Depth resolve is handled via a custom shader and therefore cannot
use the transient texture path.
This is fixes the black screen bug when MSAA is turned on and
when using the latest MoltenVK (1.2.11).
Subpasses should not be used anyways due to the result of WebGPUDriver::isFrameBufferFetchSupported. However, we need to make sure the GLSL is not generated for WebGPU, or Tint is unable to convert.
Initial groundwork in creating WebGPU backend components, namely
the instance, adapter, device, and queue.
If configured to do so, the backend will print out details about
these components.
The samples/hellotriangle.cpp was slightly modified to include a
webgpu option which allows for exercising the above, but does not
yet draw anything to the screen/window.
NOTE: This has only been sanity tested with hello triangle
on Mac OS and the Android emulator at this time, NOT IOS,
Windows, or Linux yet.
When the feature flags assert_destroy_material_before_material_instance
is disabled, we emit a log instead of an assert. Unfortunately this log
would be emitted even when all material instances were destroyed.
Add support for the new createTextureExternalImage2R
API instead of createTextureExternalImageR.
Add the support to import AHardwareBuffer objects
into Vulkan in Android.
Shader model (desktop or mobile) wasn't really accounted for
in the UI. This means that we will get shaders that look like
duplicates (same variant). In this work, we pass the current
shader model from engine into the frontend and filter out
variants of a different shader model.
Moreover, for matinfo, we use a specific dbg shader model (matinfo)
to indicate it is in that mode. We add UI in matinfo to show the
shadermodel.
So UI updates as well.
- The set of active variants were not set correctly for surface
materials since the frag/vert pairs could have different
variant.
- Fix the default selection logic in the UI
- Random clean-ups
