[x3d-public] [x3dom-users] Issue with naive X3D JSON loading. Coordinate getPoints() not present

[clement at igonet.fr]

Thanks John.

I'm currently working on a converter OpenStreetMap to x3dom for representation of buildings, all that in node.js.

As a very first proof of concept, I made it: http://www.openearthview.net

It would so useful to have a more 'native' implementation of json format in x3dom library...
