Indeed and the first part is the first scene done in any ray tracer: https://en.m.wikipedia.org/wiki/Cornell_box https://en.m.wikipedia.org/wiki/Cornell_box

  It's by far not the first scene done in any ray tracer, rather an early test scene for radiosity (diffuse-only global illumination, before path tracing was developed).

    Oh I meant “when anyone today writes a toy ray tracer, this is usually the first scene you test with it”

    Which one is the oldest, Utah teapot, bunny, dragon, default material cube?
    • pixelpoet 5y ago
      I'd guess the Utah teapot, it's been around since 1975. Cornell box is from 1984, and test scenes for materials are in some way a pretty recent thing, at least how they are used now; to me the modern versions started with Maxwell Render.
