Hi farshizzo,

Thanks for all your help - I've managed to use the on-the-fly functionality like you've described and so far it shows potential. It's tempermental, but it works. :]

Now, however, I seem to be having openGL drawing errors with the on-the-fly. In VR the line draws exactly as it should, but occasionally a slight movement of the head will cause the line to disappear altogether, only to reappear when the head is moved back to it's original position. We're talking about a cm of movement here.

Any ideas?

Thanks,

Aaron
