pub fn sample_loop_to_polygon(
model: &Model,
first: CoedgeId,
n: usize,
) -> GeopResult<Vec<Vector2>>Expand description
Sample the pcurves of the loop anchored at first (in traversal order)
into a closed (u, v) polygon, n samples per coedge (the last sample of
each coedge is dropped, since it coincides with the next coedge’s first
sample).
