VkCopyAccelerationStructureToMemoryInfoKHR

Parameters for serializing an acceleration structure

typedef struct VkCopyAccelerationStructureToMemoryInfoKHR {
    VkStructureType sType;
    const void* pNext;
    VkAccelerationStructureKHR src;
    VkDeviceOrHostAddressKHR dst;
    VkCopyAccelerationStructureModeKHR mode;
} VkCopyAccelerationStructureToMemoryInfoKHR;

pub struct CopyAccelerationStructureToMemoryInfoKHR {
    s_type: vk::StructureType,
    p_next: *const c_void,
    src: vk::AccelerationStructureKHR,
    dst: vk::DeviceOrHostAddressKHR,
    mode: vk::CopyAccelerationStructureModeKHR,
}

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 of 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-src-11582

If the source acceleration structure src was constructed through deserialization, all micromap arrays the acceleration structure references that were not replaced by an acceleration structure update command must have been deserialized using the serialized data of the corresponding micromaps used to originally build the acceleration structure 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
