Why are the surfaces of the cube split into eight triangles as such? When triangulating large shapes, is there a process for how to split it up into triangles optimally, or is it done randomly?

I remember somewhere we talked about how triangulation can be done very fast via GPU. Is deciding the number of triangles that we split a face into part of the GPU's job then?

Are the two axes still perpendicular in the object space?

What determines the triangle configuration?
