C Specification

The VkAccelerationStructureMemoryRequirementsInfoKHR structure is defined as:

typedef struct VkAccelerationStructureMemoryRequirementsInfoKHR {
    VkStructureType                                     sType;
    const void*                                         pNext;
    VkAccelerationStructureMemoryRequirementsTypeKHR    type;
    VkAccelerationStructureBuildTypeKHR                 buildType;
    VkAccelerationStructureKHR                          accelerationStructure;
} VkAccelerationStructureMemoryRequirementsInfoKHR;


  • sType is the type of this structure.

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

  • buildType selects the build types whose memory requirements are being queried.

  • type selects the type of memory requirement being queried. VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_OBJECT_KHR returns the memory requirements for the object itself. VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_BUILD_SCRATCH_KHR returns the memory requirements for the scratch memory when doing a build. VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_UPDATE_SCRATCH_KHR returns the memory requirements for the scratch memory when doing an update.

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