This is a raytracer implemented using OpenGL.
Currently there are two modules, one of which takes as input an object file and displays it using the OpenGL routines. The other module displays the output of the raytrace. The shading has not been accounted for yet.
The geometry with 2 spheres and 2 point lights is hardcoded as of now.
To install OpenGL 2.0 on Ubuntu 16.04:
sudo apt-get install freeglut3 freeglut3-dev libglew1.5 libglew1.5-dev libglu1-mesa libglu1-mesa-dev libgl1-mesa-glx libgl1-mesa-dev
Compile:
make
Execute:
./bin/main
Press r to switch between the object and Raytrace mode.
In the raytrace mode, w, a, s, d can be used to move the eye position.
The entire project has been written in C++. Unlike most raytracers, instead of rendering an image of the output, I have rendered it on the screen using OpenGL(2.0). The program also implements an .obj file importer and is capable of displaying the geometry in both, the raytracer output as well as the through OpenGL routines.
The importer uses the winged-edge data structure for the geometry.
