C Specification

The VkCopyMemoryToAccelerationStructureInfoKHR structure is defined as:

// Provided by VK_KHR_acceleration_structure
typedef struct VkCopyMemoryToAccelerationStructureInfoKHR {
    VkStructureType                       sType;
    const void*                           pNext;
    VkDeviceOrHostAddressConstKHR         src;
    VkAccelerationStructureKHR            dst;
    VkCopyAccelerationStructureModeKHR    mode;
} VkCopyMemoryToAccelerationStructureInfoKHR;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • src is the device or host address to memory containing the source data for the copy.

  • dst is the target acceleration structure for the copy.

  • mode is a VkCopyAccelerationStructureModeKHR value specifying additional operations to perform during the copy.

Description

Valid Usage

  • VUID-VkCopyMemoryToAccelerationStructureInfoKHR-src-04960
    The source memory pointed to by src must contain data previously serialized using vkCmdCopyAccelerationStructureToMemoryKHR, potentially modified to relocate acceleration structure references as described in that command

  • VUID-VkCopyMemoryToAccelerationStructureInfoKHR-mode-03413
    mode must be VK_COPY_ACCELERATION_STRUCTURE_MODE_DESERIALIZE_KHR

  • VUID-VkCopyMemoryToAccelerationStructureInfoKHR-pInfo-03414
    The data in src must have a format compatible with the destination physical device as returned by vkGetDeviceAccelerationStructureCompatibilityKHR

  • VUID-VkCopyMemoryToAccelerationStructureInfoKHR-dst-03746
    dst must have been created with a size greater than or equal to that used to serialize the data in src

Valid Usage (Implicit)

  • VUID-VkCopyMemoryToAccelerationStructureInfoKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_COPY_MEMORY_TO_ACCELERATION_STRUCTURE_INFO_KHR

  • VUID-VkCopyMemoryToAccelerationStructureInfoKHR-pNext-pNext
    pNext must be NULL

  • VUID-VkCopyMemoryToAccelerationStructureInfoKHR-dst-parameter
    dst must be a valid VkAccelerationStructureKHR handle

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