Member Function Documentation

AddBufferMemoryBarrier()

virtual void impeller::ComputePass::AddBufferMemoryBarrier ( )

pure virtual

Ensures all previously encoded compute command's buffer writes are visible to any subsequent compute commands.

On Vulkan, it does not matter if the compute command is in a different command buffer, only that it is executed later in queue order.

AddTextureMemoryBarrier()

virtual void impeller::ComputePass::AddTextureMemoryBarrier ( )

pure virtual

Ensures all previously encoded compute command's texture writes are visible to any subsequent compute commands.

On Vulkan, it does not matter if the compute command is in a different command buffer, only that it is executed later in queue order.

Compute()

virtual fml::Status impeller::ComputePass::Compute ( const ISize &  grid_size )

pure virtual

EncodeCommands()

virtual bool impeller::ComputePass::EncodeCommands ( ) const

pure virtual

Encode the recorded commands to the underlying command buffer.

Returns

If the commands were encoded to the underlying command buffer.
