I am often asked why X3D and VRML players have not consolidated down to 1 or 2 implementations. The question typically comes about due to the costs of maintaining so many different implementations. Why can't we just have one solid implementation and all use that? Wouldn't it be much easier if like Flash we had one system for content authors to deploy too?...
