The XrEndFrameOp operator completes the rendering of a single OpenXR frame by passing populated color and depth buffer for the left and right eye to the OpenXR device. Note that a single connection xr_frame from XrBeginFrameOp to XrEndFrameOp is required to synchronize the OpenXR calls issued by the two operators.

holoscan::openxr::XrEndFrameOp#

Parameters#

  • XrSession: A class that encapsulates a single OpenXR session
  • type: holoscan::openxr::XrSession

Inputs#

Render buffers populated by application

  • color_buffer: color buffer
  • type: holoscan::gxf::VideoBuffer
  • depth_buffer: depth buffer
  • type: holoscan::gxf::VideoBuffer

OpenXR synchronization

  • XrFrame: connection to synchronize XrBeginFrameOp and XrEndFrameOp
  • type: XrFrame

Note:

  • XrCudaInteropSwapchain: A class that encapsulates the Vulkan buffers of the OpenXR runtime and compatible CUDA buffer to provide interoperability between ClaraViz and OpenXR
