Are there other ways to implement vertex shaders beside the vertex program extension and Cg?

Yes, there are two possible ways:
1. use directX http://www.opengl.org/discussion_boards/ubb/wink.gif
2. do it yourself on the cpu...

Thanks AdrianD!

:-) Vertex Shaders with opengl on nvidia cards.

Are vp or Cg then the only way?

These provide similar functionality,

EXT_vertex_shader ( ATI, possibly others )
NV_vertex_program ( NV, 3Dlabs, others ? )
ARB_vertex_program ( most will likely have this )

@PH: Are those possible on nvidia cards?

ARB_vertex_program is the one to wait for. It will be supported by all the major companies ( those that have the hardware capable of supporting it ).

It's a pretty new extension so it's not available in any public drivers yet.
