when using the thread pool we were destroying the shaders immediately,
we need to defer this until we query the program link status, so that
in case of failure we can query each shader compile status.
we make the shader handles part of the promise/future so they can be
transferred to the main thread, just like the program id is.
vkCmdEndDebugUtilsLabelEXT expects that a label was "pushed" onto
the command queue (as described in the spec). It is possible to push
labels across command buffers, but the pushed label must still be in
the queue (unexecuted) when End is called. This implies that we need
to make sure the labels are in a good state (all popped) when
vkQueueSubmit is called.
- We add a stack to carry the labels across vkQueueSubmit.
- Also add CPU time durations between push and pop to provide rough
CPU execution times (in debug).
- Add systrace markers for Android systrace
- Validation failing due to incorrect layout wrt Blitter
render pass.
- Clear colors are also not needed for blitter renderpass.
- SAMPLEABLE + DEPTH_ATTACHMENT needs to have the correct layout.
- Timer query stashed a pointer to VulkanCommandBuffer, but this
points to an object that can be reused.
- We use the shared_ptr'd fence object instead to track whether
the query request has been completed.
It supports KHR_parallel_shader_compile as well as a
thread pool of GL contexts.
- we have a new 2-priorities queue for shader compilation
- use this feature in gltfio in the ubershader case
There was two related issues:
- we need to "latch" the new TextureView size when its resized. That
can only be done by recreating the EGLSurface (i.e. recreating the
SwapChain). UiHelper now calls onNativeWindowChanged in the case of
the TextureView resize, so clients can recreate their SwapChain.
- we also needed to make sure that all current filament frames have
finished to render (i.e. the last eglSwapBuffers has been called) so
that they don't pick-up a new size (this happens after
eglSwapBuffers) that doesn't match the viewport.
Fixes b/282220665
this is needed on armv7 because we use alignas to get strcture-alignment,
but that also implies (to the compiler) that the structure itself
is aligned properly.
the math needs to be maintained in highp, including during the blur
pass.
we add the ability to specify a "precision" qualifier to the "output"
of a post-process material.
we also remove the mediump clamping we used to do on mobile, it shouldn't
be done automatically behind the scenes, it's up to the shaders to do
it if it makes sense.
- flush() and wait() before destroying a swapchain
- Make sure the debug marker extension is enabled under correct
circumstances.
- Change shared_ptrs to unique_ptrs and raw pointers.
- Rename most teardown methods to terminate()
- Introduce new custom swapchain API for VulkanPlatform.h
- Implement the API for the base VulkanPlatform by refactoring
the existing swapchain code.
- VulkanSwapChain is now a wrapper for VulkanPlatform's
swap chain API.
- Actual implementation is in
vulkan/platform/VulkanPlatformSwapChainImpl.{h,cpp}
this is implemented by here by using the skybox texture and blurring it
with the irradiance filter + mipmapping. This only creates a subtle
anisotropic phase-function effect.
- we must sort commmands *after* we have added all commands!
- custom commands could change the UBO/Sampler bindings so we need
to make sure to invalidate them after executing the command.
When sampling the fog color from the IBL we need to take into account
the IBL transform. This broke recently when the for calculation was
moved in user world coordinates.
