# vkDestroyAccelerationStructureKHR(3) Manual Page

## Name

vkDestroyAccelerationStructureKHR - Destroy an acceleration structure object

Loading… please wait.

## C Specification

To destroy an acceleration structure, call:

    // Provided by VK_KHR_acceleration_structure
    void vkDestroyAccelerationStructureKHR(
        VkDevice                                    device,
        VkAccelerationStructureKHR                  accelerationStructure,
        const VkAllocationCallbacks*                pAllocator);

## Parameters

- `device` is the logical device that destroys the acceleration structure.

- `accelerationStructure` is the acceleration structure to destroy.

- `pAllocator` controls host memory allocation as described in the Memory Allocation chapter.

## Description

Valid Usage

- VUID-vkDestroyAccelerationStructureKHR-accelerationStructure-02442
  All submitted commands that refer to `accelerationStructure` must have completed execution

- VUID-vkDestroyAccelerationStructureKHR-accelerationStructure-02443
  If `VkAllocationCallbacks` were provided when `accelerationStructure` was created, a compatible set of callbacks must be provided here

- VUID-vkDestroyAccelerationStructureKHR-accelerationStructure-02444
  If no `VkAllocationCallbacks` were provided when `accelerationStructure` was created, `pAllocator` must be `NULL`

Valid Usage (Implicit)

- VUID-vkDestroyAccelerationStructureKHR-device-parameter
  `device` must be a valid VkDevice handle

- VUID-vkDestroyAccelerationStructureKHR-accelerationStructure-parameter
  If `accelerationStructure` is not VK_NULL_HANDLE, `accelerationStructure` must be a valid VkAccelerationStructureKHR handle

- VUID-vkDestroyAccelerationStructureKHR-pAllocator-parameter
  If `pAllocator` is not `NULL`, `pAllocator` must be a valid pointer to a valid VkAllocationCallbacks structure

- VUID-vkDestroyAccelerationStructureKHR-accelerationStructure-parent
  If `accelerationStructure` is a valid handle, it must have been created, allocated, or retrieved from `device`

Host Synchronization

- Host access to `accelerationStructure` must be externally synchronized
