vkCopyAccelerationStructureToMemoryKHR

To copy an acceleration structure to host accessible memory, call:

VkResult vkCopyAccelerationStructureToMemoryKHR(
    VkDevice device,
    VkDeferredOperationKHR deferredOperation,
    const VkCopyAccelerationStructureToMemoryInfoKHR* pInfo);

• device is the device which owns pInfo→src.
• deferredOperation is an optional VkDeferredOperationKHR to request deferral for this command.
• pInfo is a pointer to a VkCopyAccelerationStructureToMemoryInfoKHR structure defining the copy operation.

This command fulfills the same task as vkCmdCopyAccelerationStructureToMemoryKHR but is executed by the host.

This command produces the same results as vkCmdCopyAccelerationStructureToMemoryKHR, but writes its result directly to a host pointer, and is executed on the host rather than the device. The output may not necessarily be bit-for-bit identical, but it can be equally used by either vkCmdCopyMemoryToAccelerationStructureKHR or vkCopyMemoryToAccelerationStructureKHR.
