I truly believe that ray tracing is the future of digital imaging and augmented reality. Being able to go much further than rasterization in terms of image quality, ray-tracing also makes it easy to compute, for example, the amount of light received by an object.
The nature of ray-tracing, and the techniques used for its implementation can be reused to run scenarios such as calculating interactions between atoms or determining what the surface of contact would be between two molecules.
