This is a C++ framework for a raytracer. It is created for the Computer Science course "Introduction to Computer Graphics" taught at the University of Groningen by Tobias Isenberg.
Author: Maarten Everts
This framework is inspired by and uses code of the raytracer framework of Bert Freudenberg that can be found at http://isgwww.cs.uni-magdeburg.de/graphik/lehre/cg2/projekt/rtprojekt.html
main.cpp : Contains main(), starting point. Responsible for parsing command-line arguments.
raytracer.cpp/.h : Raytracer class. Responsible for reading the scene description, starting the raytracer and writing the result to an image file.
scene.cpp/.h : Scene class. Contains code for the actual raytracing.
image.cpp/.h : Image class, includes code for reading from and writing to PNG files.
light.cpp/.h : Light class and Ray class.
object.cpp/.h : Object class. Represents an object in the scene.
sphere.cpp/.h : Sphere class, which is a subclass of the Object class. Respresents a sphere in the scene.
triple.cpp/.h : Triple class. Represents a 3-dimensional vector which is used for colors, points, and vectors. Includes a number of useful functions and operators, see the comments in triple.h.
lodepng.cpp/.h : Code for reading from and writing to PNG files, used by the Image class. LodePNG is created by Lode Vandevenne and can be found at http://members.gamedev.net/lode/projects/LodePNG/.
yaml/* : Code for parsing YAML documents. Created by Jesse Beder, can be obtained from http://code.google.com/p/yaml-cpp/. See also yaml/license.txt.
