I would like some references for Introduction to ray Tracing and possible algorithms/code for the same. In particular, it is for Terrain Data over a regular grid.

You can write to the Yale computer science department and request a copy of Research Report RR-639 "Grid Tracing: Fast Ray Tracing for Height Fields" for info an algorithm specifically developed for ray tracing terrain models. Also see Mastin et al. "Fourier Synthesis of Ocean Scenes" in IEEE CG&A March, 1987 for an alternative approach. _____________________________________________________________________ Ken Musgrave arpanet: musgrave-forest@yale.edu Yale U.
