Hi, i'm reading about matrices right now and I get how to make a rotation matrix scale matrix and all those, but what do i do with them once i've made them? like i've made a 4 * 4 rotation matrix, and then i just multiplied it with a vector and i just incremented the angle and kept multiplying is that right? but on thing was when i had the angle at 0 it didnt point straight up it pointed at like 20 maybe 45 degrees, does this sound right?...and to make the matrices "work" all i do is multiply them by a point(s)?
