Computability and complexity of ray tracing
TL;DR: It is shown that ray-tracing problems in some three-dimensional simple optical systems (purely geometrical optics) are undecidable.
Proceedings ArticleDOI
The computability and complexity of optical beam tracing
TL;DR: The results show that, depending on the optical model, ray tracing is sometimes undecidable, sometimes PSPACE-hard, and sometimes in PSPACE.
