pub fn triangulate_simple(ring: &[Point2]) -> GeomResult<Vec<[u32; 3]>>Expand description
Triangulate a simple CCW polygon by ear clipping.
Returns index triples into ring. Fails rather than emitting a partial fan:
a caller that receives triangles must be able to trust they cover the input.
ยงErrors
GeomError::InvalidInput for a NaN or infinite coordinate, which no
orientation predicate can decide; GeomError::Degenerate for a ring that
is too short, self-intersecting or without area.
