+a long story short, homogeneous coordinates are best to deal with transformation
 and projections in 3D. In our case, because we're dealing with vertices (and
 not vectors), we only need to add 1 as the fourth coordinates (w) to all our
 vertices. Then we can apply the perspective transformation using the dot
