C Specification

The VkCopyAccelerationStructureInfoKHR structure is defined as:

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

Members

  • 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 target acceleration structure for the copy.

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

Description

Valid Usage

  • VUID-VkCopyAccelerationStructureInfoKHR-mode-03410
    mode must be VK_COPY_ACCELERATION_STRUCTURE_MODE_COMPACT_KHR or VK_COPY_ACCELERATION_STRUCTURE_MODE_CLONE_KHR

  • VUID-VkCopyAccelerationStructureInfoKHR-src-04963
    The source acceleration structure src must have been constructed prior to the execution of this command

  • VUID-VkCopyAccelerationStructureInfoKHR-src-03411
    If mode is VK_COPY_ACCELERATION_STRUCTURE_MODE_COMPACT_KHR, src must have been constructed with VK_BUILD_ACCELERATION_STRUCTURE_ALLOW_COMPACTION_BIT_KHR in the build

  • VUID-VkCopyAccelerationStructureInfoKHR-buffer-03718
    The buffer used to create src must be bound to device memory

  • VUID-VkCopyAccelerationStructureInfoKHR-buffer-03719
    The buffer used to create dst must be bound to device memory

  • VUID-VkCopyAccelerationStructureInfoKHR-dst-07791
    The range of memory backing dst that is accessed by this command must not overlap the memory backing src that is accessed by this command

Valid Usage (Implicit)

  • VUID-VkCopyAccelerationStructureInfoKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_COPY_ACCELERATION_STRUCTURE_INFO_KHR

  • VUID-VkCopyAccelerationStructureInfoKHR-pNext-pNext
    pNext must be NULL

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

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

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

  • VUID-VkCopyAccelerationStructureInfoKHR-commonparent
    Both of dst, and src must have been created, allocated, or retrieved from the same VkDevice
