@pcwalton this is useful for generating geometries. For resolution independent rendering, the conversion to the following approach shouldn't be difficult. https://threejs.org/examples/webgl_shaders_vector.html …
For what it’s worth, I like the libtess approach of monotone polygon decomposition a lot better than ear clipping. I just have an engineer’s bias toward simplicity, which is why I like trapezoidation :)

libTess is academically impeccable - but it produces a lot of tall very skinny triangles due to the horizontal sweepline.

Ditto with trapezoidation. In fact I believe trapezoidation plus monotone polygon decomposition is *equivalent* to the libtess approach.
