C Specification
The VkPartitionedAccelerationStructureInstancesInputNV structure is defined as:
// Provided by VK_NV_partitioned_acceleration_structure
typedef struct VkPartitionedAccelerationStructureInstancesInputNV {
VkStructureType sType;
void* pNext;
VkBuildAccelerationStructureFlagsKHR flags;
uint32_t instanceCount;
uint32_t maxInstancePerPartitionCount;
uint32_t partitionCount;
uint32_t maxInstanceInGlobalPartitionCount;
} VkPartitionedAccelerationStructureInstancesInputNV;
Members
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
flags
is a bitmask of VkBuildAccelerationStructureFlagsKHR specifying flags for the PTLAS build operation. -
instanceCount
is the number of instances in this PTLAS. -
maxInstancePerPartitionCount
is the maximum number of instances per partition in the PTLAS. -
partitionCount
is the number of partitions in the PTLAS. -
maxInstanceInGlobalPartitionCount
is maximum number of instances in the global partition.
Description
If the pNext
chain includes a
VkPartitionedAccelerationStructureFlagsNV structure, then that
structure specifies additional flags for the PTLAS.
