debug visualizations in fields like computer vision, 3D modeling, or really anything that has a direct visual representation very naturally pull themselves into these debug transformations much more readily than maybe regular data structures and algorithms do. The more complex the transformation the more useful the debugger visualization becomes. It probably doesn't need to be turned on all the time though, it may be an expensive proposition for sure, but when you need to bring out the big guns--by all means visualize away.
