title: How to start a triangulation on a set of (boundary) points
body: <p>I have a set of (boundary) points and I want to start triangulating them. From all references that I found, the authors only mentioned methods on how to add new points and hence create new edges (at the same time remove the old, bad points/edges), assuming that the points have been triangulated initially. So, how do I do the FIRST triangulation before I can use all the suggested methods (to add new points and edges) in the literature. For a simple case, say, if I have a circle with boundary points (x,y)=(r cos\theta,r sin\theta), I could possibly create a triangle for every three neighboring points. But then, there will be no edge crossing the region near the center of the circle. </p>
