FFP / VertexShader Water Code - 05/15/04 07:36
Hopefully someone can get this to work on all cards. And hopefully they will post it! 
After getting the EMBM to appear on all cards the envirmonment map still needs to be projected like "CameraSpaceRelflexionVector". I think that the NVidia SDK/Effects browser has a vertexshader that is an implementation of "CameraSpaceRelflexionVector". Something to keep in mind. Also, ventilators vertexshader for mapping the thing to a plane may be of help.
There is also something that is not working right with the texcoord of "envmap"??
This is essentially the minimal code that runs on my ATI Radeon 9200

Hopefully, you have the Geforce problem figured out(wish I had a Geforce card to help you test).
