Uses the graphics pipeline to both blit and transpose the 3ds-formatted
textures. Does not read from the actual texture just yet since we dont
write to the descriptor just yet. Some other patterns need to line up
before then.
A utility class from a personal project for managing a heap of
descriptors of a particular layout.
Allows the display graphics pipeline to be successfully created,
satisfying its descriptor layout issues.
This will eventually need to move into a cache, but this is introducing
some foundational patterns so that we know how to properly design a
pipeline cache. Currently does not provide a `DescriptorSetLayout`
argument. Causing validation errors. This will be a general-case cache
right from the get-go.
Now there is just one primary command buffer where all work is enqueued
into. At the end of the frame, the next frame's CPU-side fence is waited
on before resetting and beginning its command buffer again for
recording. This command buffer must always be in the RECORDING state.
While we wait on the CPU-side fence for these command buffers, we must
also wait on the GPU-side semaphore to be compliant to validation
layers synchronization. We still get an error on the very first frame
since it will wait for a semaphore that has nothing signaling it.
Rather than allocating new command buffers for each small task, schedule
all work onto the frame's main command buffer to be dispatched at
display-time. Fixes all layout transition and synchronization issues.
Technically we can generate every possible render-pass up-front based on
the possible combinations of ColorFmt and DepthFmt, but we should only
allocate what the game asks for. Save that pattern for pipelines.
This surface is managed by SDL itself, so there is no need to keep it in
a Unique handle for us to delete. Fixes the bug where vulkan crashes
during shutdown.
Instead of operating directly on the swapchain images, we have our own
top/bottom framebuffer images that will be rendered to independent of
having an available swapchain. The images are blitted into the swapchain
images, allowing for resizing too!
