C Specification

To copy an acceleration structure call:

// Provided by VK_KHR_ray_tracing
void vkCmdCopyAccelerationStructureKHR(
    VkCommandBuffer                             commandBuffer,
    const VkCopyAccelerationStructureInfoKHR*   pInfo);

Parameters

  • commandBuffer is the command buffer into which the command will be recorded.

  • pInfo is a pointer to a VkCopyAccelerationStructureInfoKHR structure defining the copy operation.

Description

Valid Usage
  • VUID-vkCmdCopyAccelerationStructureKHR-None-03556
    All VkAccelerationStructureKHR objects referenced by this command must be bound to device memory

  • VUID-vkCmdCopyAccelerationStructureKHR-pNext-03557
    The VkDeferredOperationInfoKHR structure must not be included in the pNext chain of the VkCopyAccelerationStructureInfoKHR structure

Valid Usage (Implicit)
  • VUID-vkCmdCopyAccelerationStructureKHR-commandBuffer-parameter
    commandBuffer must be a valid VkCommandBuffer handle

  • VUID-vkCmdCopyAccelerationStructureKHR-pInfo-parameter
    pInfo must be a valid pointer to a valid VkCopyAccelerationStructureInfoKHR structure

  • VUID-vkCmdCopyAccelerationStructureKHR-commandBuffer-recording
    commandBuffer must be in the recording state

  • VUID-vkCmdCopyAccelerationStructureKHR-commandBuffer-cmdpool
    The VkCommandPool that commandBuffer was allocated from must support compute operations

  • VUID-vkCmdCopyAccelerationStructureKHR-renderpass
    This command must only be called outside of a render pass instance

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

  • Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
