I've been working on a little java 3D program to read and display G2 recording files ( .rec files). I was motivated to do this in reviewing pattern contest practice I have been doing: are my wings level, are my loops round, are roll exit and entry level, is roll speed consistent, etc...

So far I can read the file, and display a little airplane (correctly oriented with respect to: x,y position, height, pitch, roll, yaw) at it's position every 1/10 second or so. This displays, for example, a series of little airplanes that show the loop pattern that has been performed. From there, I can change the view such that I can view from any position relative to the loop: above, below, from the side, front, etc.

Does anybody have any interest in this?
What type of features would make it a useful tool?
