After long searching of the right VRML plugin I'm using Flux Player to view 3D scenes.
Sadly it runs only under Windows.
My creations:
MultiDiary3D - very early version of a database oriented system that uses dynamic construction of the 3D scene for its user interface. It was heavily inspired by the project SkyBoard (www.dzana.sk).
Used technologies: X3D, ECMAScript, PHP
