C Specification

The VkWriteDescriptorSetAccelerationStructureNV structure is defined as:

typedef struct VkWriteDescriptorSetAccelerationStructureNV {
    VkStructureType                     sType;
    const void*                         pNext;
    uint32_t                            accelerationStructureCount;
    const VkAccelerationStructureNV*    pAccelerationStructures;
} VkWriteDescriptorSetAccelerationStructureNV;


  • sType is the type of this structure.

  • pNext is NULL or a pointer to an extension-specific structure.

  • accelerationStructureCount is the number of elements in pAccelerationStructures.

  • pAccelerationStructures are the acceleration structures to update.


Valid Usage
  • accelerationStructureCount must be equal to descriptorCount in the extended structure

  • Each acceleration structure in pAccelerationStructures must have been created with VK_ACCELERATION_STRUCTURE_TYPE_TOP_LEVEL_NV

Valid Usage (Implicit)

  • pAccelerationStructures must be a valid pointer to an array of accelerationStructureCount valid VkAccelerationStructureNV handles

  • accelerationStructureCount must be greater than 0
