Hi Thomas, You can switch between the Root window and the OpenGL window without closing the OpenGL window (this is not possible with X3D). You can for example, point and click on the TNodes in the Root window setting visibility attrributes and colors and see the immediate result in the OpenGL window. Look at the HELP button in the top right of the OpenGL canvas. Rene Brun Thomas Eberl wrote: > > Dear rooters, > > I have just succeeded to compile my ROOT (latest version) with OpenGL > support.
