VkCopyAccelerationStructureToMemoryInfoKHR

Parameters for serializing an acceleration structure
typedef struct VkCopyAccelerationStructureToMemoryInfoKHR {
    VkStructureType sType;
    const void* pNext;
    VkAccelerationStructureKHR src;
    VkDeviceOrHostAddressKHR dst;
    VkCopyAccelerationStructureModeKHR mode;
} VkCopyAccelerationStructureToMemoryInfoKHR;
  • sType is a VkStructureType value identifying this structure.
  • pNext is NULL or a pointer to a structure extending this structure.
  • src is the source acceleration structure for the copy
  • dst is the device or host address to memory which is the target for the copy
  • mode is a VkCopyAccelerationStructureModeKHR value specifying additional operations to perform during the copy.

Valid Usage

VUID-VkCopyAccelerationStructureToMemoryInfoKHR-src-04959

The source acceleration structure src must have been constructed prior to the execution of this command

VUID-VkCopyAccelerationStructureToMemoryInfoKHR-dst-03561

The memory pointed to by dst must be at least as large as the serialization size of src, as reported by vkWriteAccelerationStructuresPropertiesKHR or vkCmdWriteAccelerationStructuresPropertiesKHR with a query type of VK_QUERY_TYPE_ACCELERATION_STRUCTURE_SERIALIZATION_SIZE_KHR

VUID-VkCopyAccelerationStructureToMemoryInfoKHR-mode-03412

mode must be VK_COPY_ACCELERATION_STRUCTURE_MODE_SERIALIZE_KHR

Valid Usage (Implicit)

VUID-VkCopyAccelerationStructureToMemoryInfoKHR-sType-sType

sType must be VK_STRUCTURE_TYPE_COPY_ACCELERATION_STRUCTURE_TO_MEMORY_INFO_KHR

VUID-VkCopyAccelerationStructureToMemoryInfoKHR-pNext-pNext

pNext must be NULL

VUID-VkCopyAccelerationStructureToMemoryInfoKHR-src-parameter

src must be a valid VkAccelerationStructureKHR handle

VUID-VkCopyAccelerationStructureToMemoryInfoKHR-mode-parameter

mode must be a valid VkCopyAccelerationStructureModeKHR value
