Title: Basic Ray Tracer Author: Nathan Cournia Description: A simple ray tracer. Institution: Clemson University Class: CPSC805 - Advanced Computer Graphics Language: C++ Construction Time: 30 Hours Date Completed: Feburary 14, 2002 My first ray tracer. I implemented the following: Spheres Planes Multiple objects Shadows (Hard) Reflection Refraction Multiple lights Checkers Phong shading Perspective camera The code is completly object-oriented. Several problems arose during the creation of this program. Refraction gave me hell. I looked at several texts to try to figure out what I was doing wrong. Unfortunatly, the texts were of no help. Eventually, I just started arbitrarily changing code. After changing the index of refraction for a surface to (1 / ior) to (ior) if the incident ray emitted from outside of the shape, things seemed to work. I was also unable to implement soft shadows. I put a couple of hours effort into it, but only got pictures that looked horrible. Maybe next week . . . Compiling the code should be straight forward. Just type: make then ./yart outfile.ppm Source Code: cournia_yart-20020218pl1.tar.gz (12k)
