The overlay would probably not be that taxing, provided you are careful with your implementation.

I just tried to write up a point overlay in the dashboard like you said using the IMAQ Point overlay vi, but I can't seem to get it to actually plot a few points on the image, do you have any examples?

Back in 2008, we did a demo of a robot called Nitro. It had three omni wheels and used the NI Motion planning SW to calculate trajectories. Anyway, for our demo we built a path builder and a path display using the picture control. You could also do this in an XY graph. Those are both pretty performant, especially the XY graph.

Do you have any sample code left?
