I saw a few questions about context recently, so I thought I’d try to work my way through those questions, starting with some basic scenarios. First up, then, is a question about using weight maps to control subdivision.
In this case, we’re dealing with per-point and per-polygon contexts.
The context mismatch makes sense, since every polygon has more than one point, so what can a per-point weight map value mean for a polygon? One way around this would be to do something like this, and use the average of the per-point weight map values, but in a per-polygon context:
