I am a little bit confused about what this matrix does. Is my understanding correct: it projects the viewing frustum onto a 2x2x2 cube, while a method mentioned earlier projects it onto a plane of depth -d?

Hi, @0-0-00-0, I agree with you that the matrix takes a frustum and maps it onto a normalized cube. I am having a hard time understanding how the matrix will affect far and near images. How does the scale of the points in camera coordinates affect NDC?
