C Specification

To destroy an acceleration structure, call:

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


  • 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.


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
