miniRT

A 42 project that aims to build a very basic ray tracer using the school homemade library: the minilibx

Usage

./miniRT <filename>.rt

The program reads files with a .rt extension which lines follows theses rules: (All single upcase letter must have one occurence) each line is either:

1. A: Ambient lightning followed by

• an ambient lightning ratio [0.0, 1.0]
• an RGB colored range [uint8],[uint8],[uint8]

2. C: Camera followed by

• the xyz coordinates of the view point [float],[float],[float]
• the 3d normalized orientation vector [float],[float],[float]
• the field of view (FOV) [0, 180]

3. L: Light followed by

• the xyz coordinates of the view point [float],[float],[float]
• the brightness ratio [0.0, 1.0]
• an RGB colored range [uint8],[uint8],[uint8]

4. sp: Sphere

• the xyz coordinates of the view point [float],[float],[float]
• the diameter [float]
• an RGB colored range [uint8],[uint8],[uint8]

5. pl: Plane

• the xyz coordinates of the view point [float],[float],[float]
• the 3d normalized orientation vector [float],[float],[float]
• an RGB colored range [uint8],[uint8],[uint8]

6. cy: Cylinder

• the xyz coordinates of the view point [float],[float],[float]
• the 3d normalized orientation vector [float],[float],[float]
• the diameter [float]
• the height [float]
• an RGB colored range [uint8],[uint8],[uint8]
