VkPartitionedAccelerationStructureOpTypeNV(3)
Name
VkPartitionedAccelerationStructureOpTypeNV - Enum providing the type of PTLAS operation to perform
C Specification
Values which can be set in VkPartitionedAccelerationStructureOpTypeNV are:
// Provided by VK_NV_partitioned_acceleration_structure
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;Description
-
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 specifies that an instance will be updated with a new bottom level acceleration structure.
-
VK_PARTITIONED_ACCELERATION_STRUCTURE_OP_TYPE_WRITE_PARTITION_TRANSLATION_NV specifies that a partition will be assigned a translation vector.
