◆ CopyParameterDataToBuffer()

virtual void DILIGENT_CALL_TYPE Diligent::IRasterizationRateMapMtl::CopyParameterDataToBuffer ( IBuffer * pDstBuffer,
Uint64 Offset ) const
pure virtual

Copy rasterization rate map parameters to the buffer.

Parameters
[in]pDstBuffer- Parameter buffer that will be used in the resolve pass. The buffer must be created with USAGE_UNIFIED.
[in]Offset- Offset in the buffer; must be a multiple of alignment returned by GetParameterBufferSizeAndAlign().

◆ GetPhysicalGranularity()

virtual void DILIGENT_CALL_TYPE Diligent::IRasterizationRateMapMtl::GetPhysicalGranularity ( Uint32 & XGranularity,
Uint32 & YGranularity ) const
pure virtual

The granularity, in physical pixels, at which the rasterization rate varies. For better performance, tile size should be a multiple of physical granularity.
