VkPartitionedAccelerationStructureOpTypeNV

Values which can be set in VkPartitionedAccelerationStructureOpTypeNV are:

typedef enum VkPartitionedAccelerationStructureOpTypeNV {
    VK_PARTITIONED_ACCELERATION_STRUCTURE_OP_TYPE_WRITE_INSTANCE_NV = 0,
    VK_PARTITIONED_ACCELERATION_STRUCTURE_OP_TYPE_UPDATE_INSTANCE_NV = 1,
    VK_PARTITIONED_ACCELERATION_STRUCTURE_OP_TYPE_WRITE_PARTITION_TRANSLATION_NV = 2,
} VkPartitionedAccelerationStructureOpTypeNV;

• VK_PARTITIONED_ACCELERATION_STRUCTURE_OP_TYPE_WRITE_INSTANCE_NV is used to assign a transformed bottom level acceleration structure to an instance and partition. This is similar to VkAccelerationStructureInstanceKHR that defines the properties and transformations for a single instance in non-partitioned TLAS. Any partition that contains at least one of the affected instances will have their internal acceleration structure rebuilt.
• VK_PARTITIONED_ACCELERATION_STRUCTURE_OP_TYPE_UPDATE_INSTANCE_NV indicates that an instance will be updated with a new bottom level acceleration structure.
• VK_PARTITIONED_ACCELERATION_STRUCTURE_OP_TYPE_WRITE_PARTITION_TRANSLATION_NV indicates that a partition will be assigned a translation vector.
