Last week I received an email from Fabien Chauvire from Redway3D, a graphics component company from France, known for their redsdk 2D/3D graphics engine. The email pointed me to this page on the Redway3D web site which I think some of you who develop CAD software may find interesting. From what I understand Redway3D is offering a service whereby they will prototype your existing CAD software to use their graphics engine and show you how the graphics will look and feel. And they will do this for free without the need of any commitment from your side.
If this interests you please feel free to contact them.
