A fairly simple raytracer I wrote as a final project for my graphics class. Just run make to compile on OS X or Linux. Then run the generated raytrace executable. It will render the scene and then write it as a PNG file to raytrace.png in the current working directory.
Features of my raytracer include:
- the ability to display spheres, planes, and rectangles
- texture mapping for rectangles
- orthographic and perspective viewing
- point light sources
- full-screen anti-aliasing
If you want to modify the drawing parameters of the scene, just modify the variables at the top of raytrace.cpp. If you want to change the scene itself, just modify the createScene function in raytrace.cpp. If you want to extend the raytracer with more types of objects, just extend the GeometricObject class from scene.h (which will involve also creating your own extension of the Intersection class).
