VkClusterAccelerationStructureTriangleClusterInputNV

The VkClusterAccelerationStructureTriangleClusterInputNV structure is defined as:

typedef struct VkClusterAccelerationStructureTriangleClusterInputNV {
    VkStructureType sType;
    void* pNext;
    VkFormat vertexFormat;
    uint32_t maxGeometryIndexValue;
    uint32_t maxClusterUniqueGeometryCount;
    uint32_t maxClusterTriangleCount;
    uint32_t maxClusterVertexCount;
    uint32_t maxTotalTriangleCount;
    uint32_t maxTotalVertexCount;
    uint32_t minPositionTruncateBitCount;
} VkClusterAccelerationStructureTriangleClusterInputNV;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• vertexFormat is the VkFormat of each vertex element.
• maxGeometryIndexValue is the maximum geometry index value for any constructed geometry.
• maxClusterUniqueGeometryCount is the maximum number of unique values of the geometry index for each cluster or cluster template.
• maxClusterTriangleCount is the maximum number of triangles in a cluster or cluster template.
• maxClusterVertexCount is the maximum number of unique vertices in the cluster’s index buffer.
• maxTotalTriangleCount is the sum of all triangles across all clusters or cluster templates.
• maxTotalVertexCount is the maximum number of vertices across all clusters or cluster templates.
• minPositionTruncateBitCount is the least value specified in cluster build in VkClusterAccelerationStructureBuildTriangleClusterInfoNV::positionTruncateBitCount or cluster template build in VkClusterAccelerationStructureBuildTriangleClusterTemplateInfoNV::positionTruncateBitCount.
