I had assumed that if I draw an object, then translate, then draw the next object based on their stored local positions they would be drawn at their respective distances.
Any hints? I know I probably seem completely ignorant but I'm going out of my mind with the repeated suggestions of gluLookAt which I cannot use due to the lack of glut on the platform I'm working in.
Greatly appreciate any guidance.
