This is a simplest possible raytracer written in C, with minimal usage of pointers and external libraries, for easy understanding of the basic theory (more details).
We did not make a makefile because it's too easy to compile:
gcc raytracer.c -lm
Run the default executable created by gcc named as a.out as:
./a.out
Above executable will create a ppm file, to view, use ImageMagick as:
display output.ppm
Some points for performance sake:
- Image Size: for quick testing, use something like 320x240
- Recursion Depth: Can be kept 0 for no reflections/refractions
- Cone and Cylinder can use smaller resolution, default image uses 32
- Sphere resolution, unlike Cone and Cylinder, is power of 4
Thank you for downloading our code.
