MiniRT is a simple raytracing engine that renders 3D scenes with basic shapes, lighting and camera control.
- Objects supported: Sphere, plane, cylinder
- Transformation: Objects can translated, rotated and scaled
- Ambient light: Color and brightness
- Light: Position and brightness
- Camera: Position, direction and field of view

|---|---|
| Parsing | Custom parser for .rt input file into meaningful data |
| Library | Use MLX42 library to create the window and render the given image |
| Math | 3D vector and matrix manipulation library |
| Raytracing | Cast ray from view position into world through the viewport |
| Intersections | Keep all the objects in origo, inverse transformation matrix applied to ray. Use math equations to calulate intersections |
| Light model | Object reflection based on Phong illumation model: sum of ambient, diffuse and specular light components |
| Shading computation | Cast ray from hit of the object to lightsource to detect any occlusion |
| Camera | 3D camera placement and directions setup |
