Does that D3D 3.0 app get access to any new features? OpenGL 3.1 adds new ARB extensions to OpenGL 2.1, so that old OpenGL apps (even OpenGL 1.0 apps) running on an OpenGL 2.1 implementation can access new features analogous to those found in OpenGL 3.1.

I believe that a current D3D application can query earlier versions of the D3D interface through COM. A D3D 3.0 application can still run under D3D 10.0 as I understand it... -Shayne _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
