Ray Tracing

My first RayTracer written in C99

The program can render several figures with multiple light sources.

Usage

Run make inside the repository's directory to build miniRT binary.

Program needs the path to configuration file as an argument (examples in scenes directory). If flag --save is presented as a second argument, program will make a screenshot and save it in the working directory.

Setting up the configuration file

You can specify what figures to render (plane, sphere, square, cylinder and triangle available), several light sources and points of view.

General scene settings:

• Window resolution    _{R  1280  1920}
• Ambient light (brightness, colour)    _{A  0.6  255,255,255}
• Cameras (coordinates, direction, viewing angle)    _{c  1.4,0,-1  0,0,1  70}
• Light sources (coordinates, brightness, colour)    _{l  7,7,4  0.3  255,255,255}

Figure's settings:

• Plane (coordinates, direction, colour)    _{pl  2,-1.3,0  0,1,0  245,245,245}
• Sphere (coordinates, radius, colour)    _{sp  3.2,-0.8,-1.4  0.4  60,60,60}
• Square (coordinates, direction, width, colour)    _{sq  -0.2,0.5,-2.35  1,0,0  0.7  37,245,123}
• Cylinder (coordinates, direction, width, height, colour)    _{cy  0,0,0  0,1,0  1  2  70,90,225}
• Triangle (coordinates for each angle, colour)    _{tr  1.5,0.2,2.58  3.2,0.4,3  2.3,2,4.1  255,109,36}
