VkClusterAccelerationStructureInstantiateClusterInfoNV

The VkClusterAccelerationStructureInstantiateClusterInfoNV structure is defined as:

typedef struct VkClusterAccelerationStructureInstantiateClusterInfoNV {
    uint32_t clusterIdOffset;
    uint32_t geometryIndexOffset:24;
    uint32_t reserved:8;
    VkDeviceAddress clusterTemplateAddress;
    VkStridedDeviceAddressNV vertexBuffer;
} VkClusterAccelerationStructureInstantiateClusterInfoNV;

• clusterIdOffset is an unsigned offset applied to the clusterID value stored in the cluster template.
• geometryIndexOffset is a signed offset applied to the geometry index of each triangle.
• reserved is reserved for future use.
• clusterTemplateAddress is the address of a previously built cluster template.
• vertexBuffer is either NULL or a VkStridedDeviceAddressNV structure containing the vertex data for the indexed triangles stored in the cluster template.
