For reasons unknown, after upgrading to XCode 15.3, dlopen can
no longer find libvulkan.1.dylib. We fix it by explicitly adding
/usr/local/lib to rpath for macos.
PipelineState now holds a handle to a HwVertexBufferInfo.
DriverAPI::draw() is now technically deprecated and replaced by the
more efficient draw2(), which only takes an index offset, index count
and instance count. The Pipeline to use is now specified with a new
API bindPipeline() and the primitive to use with bindRenderPrimitive().
This allows clients to reuse RenderPrimitives and ultimately Pipelines.
This change reduces CPU usage significantly on Metal and Vulkan, by
reducing the need to lookup for a pipeline at every draw call.
The application, however, must be a "good citizen" by reusing
MaterialInstance and RenderPrimitive as much as possible. We do have
RenderPrimitive cache however, so reusing the same VertexBuffer and
associated parameters also works.
Some default materials such as defaultMaterial and skybox have discrete
material file for feature level 0.
Combine these materials as one utilizing the `-P` option of matc.
This adds a new material property (float postLightingMixFactor) which
is used to mix the original color with the post-lighting blended color.
The default value is 1.0, which keeps the current behavior.

cmgen mirrors environment maps by default so that the reflection map
appears un-mirrored. IBLPrefilter didn't do that.
EquirectangularToCubemap now takes a Config parameter that allows to
specify the mirroring, which is enabled by default.

Protected contexts are now supported by the OpenGLPlatform interface
and implemented in EGLPlatform.
Protected contexts can read from regular and protected resources but
can only write to protected resources (e.g. protected swap chains or
textures backed by protected memory. These can be created on Android
via AHardwareBuffer and EGLImage for instance).
The underlaying EGL implementation must support protected contexts.
Switching to a protected context is achieved by using a
protected-content SwapChain in Renderer::beginFrame().
A protected-content SwapChain can be created using the new
CONFIG_PROTECTED_CONTENT flag at creation time.
The OpenGL backend implementation will then use a protected context for
rendering until an unprotected SwapChain is used again.
The crux of this implementation is to use different VAOs in
the different contexts, because those can't be shared between contexts.
We also need to synchronize the state with our state cache and ensure
VAOs objects are destructed properly in the right context.
* Add new parameter -P for matc
This new matc parameter `-P` or `--material-parameter` allows users to
set material properties to the specified value.
Values passed through this matc parameters have the highest priorities.
I.e., they overwrite material properties specified in the material file.
Previously the cache would try to keep its size below a user-settable
value. This was not effective because when that value was too small,
it would cause a lot of churn every frame without actually keeping
the memory usage below the specified value.
We now evict buffer aggressively after they've not been used
(for two frames by default), but we don't cap the size of the cache.
The cache will naturally settle at the size it needs. When dynamic
resolution is used, it might be needed to increase resources
maximum age, which is a user-settable value still.
This improves performance on mobile on many scenes because the 64MB
default value was too low, causing the crash to thrash.
The validation error triggers on hellotriangle using AMD (desktop), QCOM (mobile) and Mali (mobile) GPU.
Before this MR, only a single semaphore object was used to synchronize all the calls to vkAcquireNextImage (signal) and vkQueueSubmit (wait).
The issue is that by the time vkQueueSubmit returns, the semaphore is not necessarily reset.
When multiple frames are in flight, the next call to vkAcquireNextImage might try to reuse the semaphore while it is still in the wait status.
The semaphore is reset at a driver/hardware-dependent timing that's likely to be linked to the GPU queue execution.
The solution proposed by this MR is to use a pool of semaphores big enough to cover all possible queue submissions.
Previous commit [1] changed the semantic of the index to
mBufferObjects. Here we just make sure that if a buffer has been
allocated, we don't allocate another (otherwise, we'd leak).
Also cleaned up `updateBoneIndicesAndWeights` indexing

- Add cache for ds layouts and ds
- Abstract descriptors API into VulkanDescriptorSetManager
- Note that this is just a draft and not hooked into the current
implementation.
- better naming
- TimerQueryFactory doesn't depend on OpenGLDriver anymore,
only a OpenGLContext.
- timer query factory is now owned by and accessed through OpenGLDriver
- we can't temporarily store a negative number
in the query shared state, because it now indicates an error.
This is supported only by the PlatformEGL currently. There is not much
that can be done with it either at this point. A protected swapchain is
one that can only be written by a protected context, however, there
is currently no way to create such context.
This is currently only implemented in the GLES backend and simply
exposes GL_EXT_protected_textures. There is not much that can be done
with this yet. Protected textures can't be read nor written at the
moment.
* Add a new material param, stereoscopicType
This new parameter allows us to specify which implementation of
stereoscopic rendering Filament uses for the material.
This change just includes material parameter addition and shader code
changes, so it doesn't affect the current rendering behavior.
These changes will follow as separate commits.
- render pipeline changes
- material parameter override via matc parameter
- material document update
We're going to add a new implementation of stereoscopic rendering using
multiview. Thus we want to remove the word `Instanced` from all methods
and properties.
This shader takes an array texture and a layer index to draw to the
current render target.
This will be used for debugging purpose to combine an array texture
rendered from the multiview feature that is going to be implemented
later, so that we can verify the feature properly performed.
