Using the awt AffineTranform, I would still need to calculate the x and y translation values myself from the known angle and distance values. I only need to translate one point, not a whole system of points. The AffineTransform seems like an un-needed step for translating a single point. I was hoping for a convenience method, so I didn't have to write my own translation function on top of commons math. I guess ideally, for me, the awt AffineTransform class would have something like a "getRayTranslationInstance" method, taking in an angle and distance; probably not gonna happen. I'll write my own.
