npm install libtess
See the example page for a simple example of setting up a polygon with a hole made of two contours, triangulating it, and then drawing it with WebGL.
Run the tests locally with
npm test, or in the browser here.
See the expectations viewer to compare the test geometry tessellated with the latest version of the library versus the expected (baseline) tessellation.
Tesselator or Tessellator?
Probably tessellator, but
GLUtesselator, etc is in the original GLU API handed
down from Ancient Times and "tesselator" is already all over the original source
code, so that's what we're going with.
