This is a 42 project that reqires building out own raytracer and display shapes on the screen.

This was a parter-project, so thanks to Noel for working on this project with me! :D

Simply copy and paste this command into your terminal and the program will automatically set itself up:

git clone git@github.com:Cimex404/42-miniRT.git miniRT
cd miniRT
git submodule init
git submodule update

We use two submodules for this project, namely Noel's libft42 as well as the official MLX42 graphics library.

This miniRT can do all of the following:

• Three geometric shapes (Sphere, Plane, Cylinder)
• Ambient Lighting
• Colored Point Lights
• Soft Shadow casting
• Shadow Falloff
• Ambient Occlusion
• Specular Reflections
• Dynamic Reflection
• Movement (only works smoothly with low shadow samples and a small window size)
• Shadow sample control (+/- keys)

The input is managed through .rt files. Here is an example:

C    -50,40.5,50     1,-0.3,-0.75  60
