Berta is a basic, extensible ray tracing application. For now berta only runs on OSX.
This project takes code, both directly and with modifications, from pbrt-v2 and Sverre Kvaale's implementations of Kevin Suffern's ray tracer, available here.
The project is structured in a way that hopefully makes conceptual sense. Components used around the whole application, such as the geometry and transformations, are stored in the utils folder.
The geometry classes, both conceptually and in implementation, are taken from pbrt. They were chosen because they support a wide range of operations using operator overloading. The Assert checks were removed from all methods.
