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
