KF-Ray

A ray tracing program which can create realistic images and perform parallel computing.

"Ray tracing is a technique for generating an image by tracing the path of light through pixels in an image plane. The technique is capable of producing a very high degree of photorealism ; usually higher than that of typical scanline rendering methods, but at a greater computational cost."

Wikipedia on ray tracing

KF-Ray is a ray tracing program which can perform parallel computing.

KF-Ray is purely written in C and works on an UNIX/Linux system. It can be use with several computers/clusters in the same time for parallel rendering with MPI.

KF-Ray is mostly in French (commentaries, documentation, manual) but the code is entirely in English (variable, function names). Thus, it is still easy to modify.

KF-Ray was developed during our second year engineering school.
