VkPartitionedAccelerationStructureInstancesInputNV

The VkPartitionedAccelerationStructureInstancesInputNV structure is defined as:

typedef struct VkPartitionedAccelerationStructureInstancesInputNV {
    VkStructureType sType;
    void* pNext;
    VkBuildAccelerationStructureFlagsKHR flags;
    uint32_t instanceCount;
    uint32_t maxInstancePerPartitionCount;
    uint32_t partitionCount;
    uint32_t maxInstanceInGlobalPartitionCount;
} VkPartitionedAccelerationStructureInstancesInputNV;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL 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.

If the pNext chain includes a VkPartitionedAccelerationStructureFlagsNV structure, then that structure specifies additional flags for the PTLAS.
