C Specification
The VkPhysicalDeviceClusterAccelerationStructurePropertiesNV
structure
is defined as:
// Provided by VK_NV_cluster_acceleration_structure
typedef struct VkPhysicalDeviceClusterAccelerationStructurePropertiesNV {
VkStructureType sType;
void* pNext;
uint32_t maxVerticesPerCluster;
uint32_t maxTrianglesPerCluster;
uint32_t clusterScratchByteAlignment;
uint32_t clusterByteAlignment;
uint32_t clusterTemplateByteAlignment;
uint32_t clusterBottomLevelByteAlignment;
uint32_t clusterTemplateBoundsByteAlignment;
uint32_t maxClusterGeometryIndex;
} VkPhysicalDeviceClusterAccelerationStructurePropertiesNV;
Members
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
maxVerticesPerCluster
indicates the maximum number of unique vertices that can be specified in the index buffer for a cluster. -
maxTrianglesPerCluster
indicates the maximum number of triangles in a cluster. -
clusterScratchByteAlignment
indicates the alignment required for scratch memory used in building or moving cluster acceleration structures. -
clusterByteAlignment
indicates the alignment of buffers when building cluster acceleration structures. -
clusterTemplateByteAlignment
indicates the alignment of buffers when building cluster templates. -
clusterBottomLevelByteAlignment
indicates the alignment of buffers when building bottom level acceleration structures. -
clusterTemplateBoundsByteAlignment
indicates the alignment of VkClusterAccelerationStructureBuildTriangleClusterTemplateInfoNV::pname::instantiationBoundingBoxLimit. -
maxClusterGeometryIndex
indicates the maximum geometry index possible for a triangle in an cluster acceleration structures.
Description
If the VkPhysicalDeviceClusterAccelerationStructurePropertiesNV
structure is included in the pNext
chain of the
VkPhysicalDeviceProperties2 structure passed to
vkGetPhysicalDeviceProperties2, it is filled in with each
corresponding implementation-dependent property.
