This routine has multiple stages. This stage does the following: * Rotate the ship's orientation vectors according to our pitch and roll As with the previous step, this is all about moving the other ships rather than us (even though we are the one doing the moving). So we rotate the current ship's orientation vectors (which defines its orientation in space), by the angles we are "moving" the rest of the sky through (alpha and beta, our roll and pitch), so the ship appears to us to be stationary while we rotate.
