raytrace

A ray tracing package using R

NB: The raytrace package utilises my vecspace and (optionally) vecshapes packages to define the basic geometry of the world. The vecshapes is a collection of the more interesting objects, and currently includes the geometry for the dodecahedron and teapotahedron. All are available on this github.

This package is still very much a work in progress at this stage, but I've implemented at least some elements of ray tracing so far. Lighting and shadowing are still a bit rudimentary at the moment, but it seems to all basically work.

The teapot is an interesting one. Writing the function to create the basic teapot was a 20 minute job, courtesy of the geometry at http://www.holmes3d.net/graphics/teapot/ and it validated the usefulness of the world-building functionality in the vecshapes package. But it certainly throws up the need for some better and more efficient indexing within the object hierarchy. The image above took almost an hour to render at 500x500 pixels!
