Detailed Description

Interface that defines methods to manipulate a bottom level acceleration structure (BLAS) object.

Member Function Documentation

◆ GetActualGeometryCount()

virtual xiiUInt32 xiiGALBottomLevelAS::GetActualGeometryCount ( ) const

nodiscardpure virtual

This returns the geometry count that was used to build the acceleration structure.

Returns: The number of geometries that was used to build the acceleration structure.

Note: Access to the BLAS must be externally synchronized.

Implemented in xiiGALBottomLevelASVulkan.

◆ GetGeometryDescriptionIndex()

virtual xiiUInt32 xiiGALBottomLevelAS::GetGeometryDescriptionIndex ( xiiStringView sName ) const

nodiscardpure virtual

This returns the geometry description index in the BLAS triangle or axis-aligned bounding box descriptions.

Parameters

sName - The geometry name that is specified in the BLAS triangle or axis-aligned bounding box descriptions.

Returns: The geometry the index or xiiInvalidIndex if the geometry does not exist.

Note: Access to the BLAS must be externally synchronized.

Implemented in xiiGALBottomLevelASVulkan.

◆ GetGeometryIndex()

virtual xiiUInt32 xiiGALBottomLevelAS::GetGeometryIndex ( xiiStringView sName ) const

nodiscardpure virtual

This returns the geometry index that can be used in a shader binding table.

Parameters

sName - The geometry name that is specified in the BLAS triangle or axis-aligned bounding box descriptions.

Returns: The geometry index or xiiInvalidIndex if the geometry does not exist.

Note: Access to the BLAS must be externally synchronized.

Implemented in xiiGALBottomLevelASVulkan.

◆ GetScratchBufferSizeDescription()

virtual xiiGALScratchBufferSizeDescription xiiGALBottomLevelAS::GetScratchBufferSizeDescription ( ) const

nodiscardpure virtual

This returns the scratch buffer information for the current acceleration structure.

Returns: The scratch buffer size description, see xiiGALScratchBufferSizeDescription.

Implemented in xiiGALBottomLevelASVulkan.
