Vrmlpad + Extrusion Editor
VrmlPad is an advanced editor for VRML coding. It's good for students who are studying the basics of VRML or prefer manual programming. The key features of VrmlPad include smart autocomplete, dynamic errors detection, visual support for the scene tree, integrated script debugger, and publishing wizard amongst others.
