VkCopyAccelerationStructureModeNV(3)

# VkCopyAccelerationStructureModeNV(3) Manual Page

## Name

VkCopyAccelerationStructureModeNV - Acceleration structure copy mode

## C Specification

Possible values of vkCmdCopyAccelerationStructureNV::`mode`, specifying additional operations to perform during the copy, are:

    typedef enum VkCopyAccelerationStructureModeNV {
        VK_COPY_ACCELERATION_STRUCTURE_MODE_CLONE_NV = 0,
        VK_COPY_ACCELERATION_STRUCTURE_MODE_COMPACT_NV = 1,
        VK_COPY_ACCELERATION_STRUCTURE_MODE_MAX_ENUM_NV = 0x7FFFFFFF
    } VkCopyAccelerationStructureModeNV;

## Description

- `VK_COPY_ACCELERATION_STRUCTURE_MODE_CLONE_NV` creates a direct copy of the acceleration structure specified in `src` into the one specified by `dst`. The `dst` acceleration structure must have been created with the same parameters as `src`.

- `VK_COPY_ACCELERATION_STRUCTURE_MODE_COMPACT_NV` creates a more compact version of an acceleration structure `src` into `dst`. The acceleration structure `dst` must have been created with a `compactedSize` corresponding to the one returned by vkCmdWriteAccelerationStructuresPropertiesNV after the build of the acceleration structure specified by `src`.
