[X3D-Public] extending a polygon with X3DOM

[John Carlson]

Is it possible to build a polyline/polygon with X3DOM on the fly (with JavaScript), or do I have to delete and add a polyline/polygon for each new point?  Say I want to add points to the polyline/polygon by clicking on cubes that I've added previously.  A simple example would be a Draw Tool where I want to draw a polyline/polygon.

Is this the distinction between an Authoring tool and  a Browser, or is there no distinction?

Trying to decide if I need WebGL, or just X3DOM + JavaScript will do.   I'm certainly hoping I don't have to do WebGL.

I've already written this app in JOGL, so I assume it's possible with WebGL.
