VkWriteDescriptorSetAccelerationStructureNV(3)

Name

VkWriteDescriptorSetAccelerationStructureNV - Structure specifying acceleration structure descriptor information

C Specification

The VkWriteDescriptorSetAccelerationStructureNV structure is defined as:

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

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • accelerationStructureCount is the number of elements in pAccelerationStructures.

  • pAccelerationStructures is a pointer to an array of VkAccelerationStructureNV structures specifying the acceleration structures to update.

Description

Valid Usage

  • VUID-VkWriteDescriptorSetAccelerationStructureNV-pAccelerationStructures-03748
    Each acceleration structure in pAccelerationStructures must have been created with VK_ACCELERATION_STRUCTURE_TYPE_TOP_LEVEL_KHR

  • VUID-VkWriteDescriptorSetAccelerationStructureNV-pAccelerationStructures-03749
    If the nullDescriptor feature is not enabled, each member of pAccelerationStructures must not be VK_NULL_HANDLE

Valid Usage (Implicit)
