C Specification

The VkAccelerationStructureMemoryRequirementsInfoNV structure is defined as:

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

Members

  • sType is the type of this structure.

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