Intel oneAPI Rendering Training Modules

Learn the Essentials of Intel® OSPRay

This foundational learning path introduces Intel® oneAPI, the Intel® oneAPI Rendering Toolkit components, and explores Intel® OSPRay, an industry-leading, ray-tracing rendering library. At a high level, see how to use the Intel OSPRay API to create high-fidelity photorealistic images. Step-by-step instructions begin with creating scenes using simple geometries, and then progress through samples to demonstrate how you can import more complicated geometries into your target scene.

After you complete the four modules, you will be able to:

  • Explain how Intel® oneAPI aligns with the rendering capabilities of the Intel® oneAPI Rendering Toolkit, including ray-surface hit testing, volumetric space iteration, and image denoise.
  • Initialize the renderer, render a single frame, and release system resources.
  • Set up scivis and pathtracer rendering modes within the code and via the command line of the executable run script, run.sh.
  • Use a basic OBJ asset file loader inside a loadObj() wrapper function to transfer data for geometry, materials, and lighting effects from the file and into the appropriate Intel OSPRay API function calls.

Asset Loading Using an OBJ/MTL File and the loadObj() Function sample icon

Module 4

Asset Loading Using an OBJ/MTL File and the loadObj() Function

  • Understand OSPRay constructs related to loading objects, and then manipulate data to achieve various effects.
  • Modify command line options of the executable run script, run.sh, to load different OBJ files.
  • Use the loadObj() wrapper function to transfer data for geometry, materials, and lighting effects from the OBJ file and into the appropriate OSPRay API function calls.
  • Modify command line options of the executable run script, run.sh, to change the camera position to account for the different object sizes in the OBJ file.
