## Name

VkCopyMicromapInfoEXT - Parameters for copying a micromap

Loading… please wait.

## C Specification

The `VkCopyMicromapInfoEXT` structure is defined as:

    // Provided by VK_EXT_opacity_micromap
    typedef struct VkCopyMicromapInfoEXT {
        VkStructureType          sType;
        const void*              pNext;
        VkMicromapEXT            src;
        VkMicromapEXT            dst;
        VkCopyMicromapModeEXT    mode;
    } VkCopyMicromapInfoEXT;

## 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 micromap for the copy.

- `dst` is the target micromap for the copy.

- `mode` is a VkCopyMicromapModeEXT value specifying additional operations to perform during the copy.

## Description

Valid Usage

- VUID-VkCopyMicromapInfoEXT-mode-07531
  `mode` must be `VK_COPY_MICROMAP_MODE_COMPACT_EXT` or `VK_COPY_MICROMAP_MODE_CLONE_EXT`

- VUID-VkCopyMicromapInfoEXT-src-07532
  The source acceleration structure `src` must have been constructed prior to the execution of this command

- VUID-VkCopyMicromapInfoEXT-mode-07533
  If `mode` is `VK_COPY_MICROMAP_MODE_COMPACT_EXT`, `src` must have been constructed with `VK_BUILD_MICROMAP_ALLOW_COMPACTION_BIT_EXT` in the build

- VUID-VkCopyMicromapInfoEXT-buffer-07534
  The `buffer` used to create `src` must be bound to device memory

- VUID-VkCopyMicromapInfoEXT-buffer-07535
  The `buffer` used to create `dst` must be bound to device memory

Valid Usage (Implicit)

- VUID-VkCopyMicromapInfoEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_COPY_MICROMAP_INFO_EXT`

- VUID-VkCopyMicromapInfoEXT-pNext-pNext
  `pNext` must be `NULL`

- VUID-VkCopyMicromapInfoEXT-src-parameter
  `src` must be a valid VkMicromapEXT handle

- VUID-VkCopyMicromapInfoEXT-dst-parameter
  `dst` must be a valid VkMicromapEXT handle

- VUID-VkCopyMicromapInfoEXT-mode-parameter
  `mode` must be a valid VkCopyMicromapModeEXT value

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