Run Intel® OSPRay Studio

This walkthrough demonstrates how to run the Intel® OSPRay Studio application. Intel OSPRay Studio is a showcase application included in the Intel® oneAPI Rendering Toolkit (Render Kit). It is an interactive and extendable ray-tracing application.

Prerequisite: Configure your system.

To run the application:

  1. Open a terminal.
  2. If you did not set up oneAPI toolkit environment permanently: Set up environment variables:
    • For root or sudo users: 
      source /opt/intel/oneapi/setvars.sh
    • For non-root users: 
      source ~/intel/oneapi/setvars.sh

    See Set up Environment Variables for other options.

    NOTE:
    If you installed the Render Kit to a custom location, make sure to replace /opt/intel/oneapi/ (for root or sudo users) or ~/intel/oneapi/ (for non-root users) with the custom installation path before running the command.
  3. Go to a writable directory and create a directory to store supporting and result files. For example, create the rk_gsg folder : 
    cd ~
    mkdir rk_gsg
    cd rk_gsg
  4. Run Intel OSPRay Studio: 
    ospStudio

    You should see an interactive rendering window:

  5. In the rendering window, go to File > Demo Scene and select one of the predefined demo scenes.

    NOTE:
    Some scenes demonstrate Intel® Open Volume Kernel Library integration capability.
  6. Review the selected scene. For example, the Multilevel Hierarchy demo looks as follows:

    You can control the scene view with a mouse as follows:

    • Right-click to move the camera in and out from the look-at point.
    • Left-click to rotate.
    • Scroll the mouse wheel to zoom in and out.
    • Drag and drop to move the camera.

    You can also use the following keyboard controls:

    • UP/DOWN: Move the camera along the Z axis (in and out).
    • ALT+UP/ALT+DOWN: Move the camera along the Y axis (up or down).
    • LEFT: Move the camera to the left along the X axis.
    • RIGHT: Move the camera to the right along the X axis.
    • W/S: Change camera elevation.
    • ALT+S: Save a frame as a file to a local directory.
    • A/D: Change camera azimuth.
    • ALT+A/ALT+D: Change camera roll.
    • G: Show/Hide the user interface.
    • Q: Quit the application.
    • P: Print a scene graph to the shell.
    • M: Print a material registry to the shell.
    • B: Print frame bounds.
    • V: Print camera parameters to the shell.
    • =: Push a location to save camera parameters.
    • -: Pop a location to save camera parameters.
    • 0-9: Set a camera snapshot.
    • Hold X, hold Y, hold Z: Keep axis constrained for camera movement.
  7. You can save output image from Menu > Save... > Screenshot in a preferred image format. The image is saved to the working rk_gsg directory as studio.<NNNN>.

  8. You can review the saved screenshot with your preferred image viewer. For example, to open the resulting images with the EoG image viewer:
