# vkDestroyAccelerationStructureKHR(3) Manual Page

## Name

vkDestroyAccelerationStructureKHR - Destroy an acceleration structure object

## C Specification

To destroy an acceleration structure, call:

    void vkDestroyAccelerationStructureKHR(
        VkDevice                                    device,
        VkAccelerationStructureKHR                  accelerationStructure,
        const VkAllocationCallbacks*                pAllocator);

or the equivalent command

    void vkDestroyAccelerationStructureNV(
        VkDevice                                    device,
        VkAccelerationStructureKHR                  accelerationStructure,
        const VkAllocationCallbacks*                pAllocator);

## Parameters

- `device` is the logical device that destroys the buffer.

- `accelerationStructure` is the acceleration structure to destroy.

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

## Description

Valid Usage

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

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

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

Valid Usage (Implicit)

- `device` must be a valid VkDevice handle

- `accelerationStructure` must be a valid VkAccelerationStructureKHR handle

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

- `accelerationStructure` must have been created, allocated, or retrieved from `device`
