C Specification

The VkAccelerationStructureMemoryRequirementsInfoNV structure is defined as:

// Provided by VK_NV_ray_tracing
typedef struct VkAccelerationStructureMemoryRequirementsInfoNV {
    VkStructureType                                    sType;
    const void*                                        pNext;
    VkAccelerationStructureMemoryRequirementsTypeNV    type;
    VkAccelerationStructureNV                          accelerationStructure;
} VkAccelerationStructureMemoryRequirementsInfoNV;


  • sType is a VkStructureType value identifying this structure.

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

  • type selects the type of memory requirement being queried. VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_OBJECT_NV returns the memory requirements for the object itself. VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_BUILD_SCRATCH_NV returns the memory requirements for the scratch memory when doing a build. VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_UPDATE_SCRATCH_NV returns the memory requirements for the scratch memory when doing an update.

  • accelerationStructure is the acceleration structure to be queried for memory requirements.


Valid Usage (Implicit)
  • VUID-VkAccelerationStructureMemoryRequirementsInfoNV-sType-sType

  • VUID-VkAccelerationStructureMemoryRequirementsInfoNV-pNext-pNext
    pNext must be NULL

  • VUID-VkAccelerationStructureMemoryRequirementsInfoNV-type-parameter
    type must be a valid VkAccelerationStructureMemoryRequirementsTypeNV value

  • VUID-VkAccelerationStructureMemoryRequirementsInfoNV-accelerationStructure-parameter
    accelerationStructure must be a valid VkAccelerationStructureNV handle
