C Specification

The VkBuildPartitionedAccelerationStructureIndirectCommandNV structure is defined as:

// Provided by VK_NV_partitioned_acceleration_structure
typedef struct VkBuildPartitionedAccelerationStructureIndirectCommandNV {
    VkPartitionedAccelerationStructureOpTypeNV    opType;
    uint32_t                                      argCount;
    VkStridedDeviceAddressNV                      argData;
} VkBuildPartitionedAccelerationStructureIndirectCommandNV;

Members

  • opType is a VkPartitionedAccelerationStructureOpTypeNV describing the type of operation.

  • argCount the number of structures in argData array.

  • argData is an array of VkStridedDeviceAddressNV structures containing the write or update data for instances and partitions in the PTLAS. The structure is dependent on opType as shown in the table below.
