## Name

VkCopyAccelerationStructureInfoKHR - Parameters for copying an acceleration structure

Loading… please wait.

## 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 the type of 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 that specifies 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-03411
  If `mode` is `VK_COPY_ACCELERATION_STRUCTURE_MODE_COMPACT_KHR`, `src` must have been built with `VK_BUILD_ACCELERATION_STRUCTURE_ALLOW_COMPACTION_BIT_KHR`

- 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

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
