[x3d-public] Water and mirrors using X3D and Castle Game Engine

[Brutzman, Donald (Don) (CIV)]

Wow, really looks great.

As you well know Michalis, these are capabilities we are pursuing for draft X3D version 4.

	X3D version 4.0 Development:  Candidate Capabilities
	http://www.web3d.org/wiki/index.php/X3D_version_4.0_Development#Candidate_Capabilities

If you are available this Friday (or the following week) it would be great to discuss further on the weekly X3D Working Group teleconference.  Membership has value...
