libtess.js

 

Polygon tesselation library, ported from the tesselator in Silicon Graphics's
reference implementation of
the OpenGL Utility Library (GLU), written primarily by
Eric Veach while at SGI.

Installation

``
npm install libtess
`

Example

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.

Tests

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.
