Ray tracing is a rendering technique known for its ability to create believable, photo-realistic computer-generated imagery. By modelling the way that light rays behave in the real world, environments can be simulated with accurate portrayals of shadows and reflections alongside a variety of many other optical effects that exist in nature.
An open-source implementation of a Ray Tracer in Java is available on GitHub. This implementation uses TornadoVM to accelerate ray tracing for rendering primitive shapes (e.g. spheres) along with the reflection and shadow effects.
