This demo is a 3D renderer written from scratch, entirely in software.
It supports vertex transformation, perspective projection, triangle/line rasterization,
lighting (ambient & specular), Z-buffer and a wireframe mode.
Feel free to play with some of the parameters below.

The model is defined by polygon triangulation and is composed of about 3000 vertices, with a color associated to each one.
Segment rasterization is done by using the Bresenham algorithm.
Triangles are filled using linear interpolation based on the color of their 3 vertices. (barycentric interpolation)

The rendering also uses a Z-buffering technique to handle correctly the depth and make the triangle rendering order-independent.

Lightning is computed based on the Gouraud shading algorithm.
