> Can someone help me understand why SDF-only techniques are valuable Out of computer graphics, I have used them a lot for modeling the evolution of curves and surfaces in a topologically-oblivious way. The terminology is slightly different (they go by silly names like "implicit snakes"), but it is the same thing. If you have ever used an "adaptive select" or "intelligent scissors" tool of a drawing program, it was probably implemented using this technique.
