  • Image-Based Lighting via Cubemaps
  • Ray Tracing & Shadow Rays

  • Quality Increase, Not Performance
    • When adding Shadow Rays to the code compared to the original implementation, the image quality improves but requires more computation time.
    • In Ray Tracing, rendering involves determining visibility for each pixel and then shading it—two separate steps.
    • Because the process involves casting rays from the camera, tracking reflections, and performing multiple ray-geometry intersection tests, it’s more computationally expensive and time-consuming.
