C Specification

// Provided by VK_KHR_ray_tracing
typedef struct VkCopyAccelerationStructureToMemoryInfoKHR {
    VkStructureType                       sType;

Members

  • 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 that specifies additional operations to perform during the copy.

Description

Valid Usage
  • 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 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 or a pointer to a valid instance of VkDeferredOperationInfoKHR

  • VUID-VkCopyAccelerationStructureToMemoryInfoKHR-sType-unique
    The sType value of each struct in the pNext chain must be unique

  • VUID-VkCopyAccelerationStructureToMemoryInfoKHR-src-parameter
    src must be a valid VkAccelerationStructureKHR handle

  • VUID-VkCopyAccelerationStructureToMemoryInfoKHR-dst-parameter
    dst must be a valid VkDeviceOrHostAddressKHR union

  • VUID-VkCopyAccelerationStructureToMemoryInfoKHR-mode-parameter
    mode must be a valid VkCopyAccelerationStructureModeKHR value
