Members

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
input is VkClusterAccelerationStructureInputInfoNV structure describing the build or move parameters for the cluster acceleration structure.
dstImplicitData is the device address for memory where the implicit build of cluster acceleration structure will be saved. If VkClusterAccelerationStructureInputInfoNV::opMode is VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_EXPLICIT_DESTINATIONS_NV or VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_COMPUTE_SIZES_NV, this value is ignored.
scratchData is the device address of scratch memory that will be used during cluster acceleration structure move or build.
dstAddressesArray is a VkStridedDeviceAddressRegionKHR that specifies addresses and stride for moved or built cluster acceleration structures, depending on the value of VkClusterAccelerationStructureInputInfoNV::opMode. If VkClusterAccelerationStructureInputInfoNV::opMode is VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_IMPLICIT_DESTINATIONS_NV and VkStridedDeviceAddressRegionKHR::deviceAddress is not 0, then the implementation writes the cluster addresses to the specified region. If VkClusterAccelerationStructureInputInfoNV::opMode is VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_EXPLICIT_DESTINATIONS_NV, the implementation reads the cluster addresses from the specified region. If VkClusterAccelerationStructureInputInfoNV::opMode is VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_COMPUTE_SIZES_NV, this member is ignored.
dstSizesArray is a VkStridedDeviceAddressRegionKHR containing sizes of moved or built cluster acceleration structures. If VkClusterAccelerationStructureInputInfoNV::opMode is VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_IMPLICIT_DESTINATIONS_NV or VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_COMPUTE_SIZES_NV, then the sizes are saved. If VkClusterAccelerationStructureInputInfoNV::opMode is VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_EXPLICIT_DESTINATIONS_NV, then the sizes are read from.
srcInfosArray is a VkStridedDeviceAddressRegionKHR where input data for the build or move operation is read from. If the stride is 0, the structures are assumed to be packed tightly. Its format is dependent on VkClusterAccelerationStructureInputInfoNV::opType as per the table below.

srcInfosCount is the device address of memory containing the count of number of build or move operations to perform. The actual value is the minimum of this value and the value specified in input.maxAccelerationStructureCount. If this value is 0, the count is determined by input.maxAccelerationStructureCount alone.
addressResolutionFlags is a bitmask of VkClusterAccelerationStructureAddressResolutionFlagBitsNV values specifying how an implementation will interpret the device addresses in this structure.
