it also runs successfully on a Matrox card, so it is definitely a driver bug. but in any case, it is probably better to stick with 2 clipping planes. thanks for your help !!! -- Peter > - Kelvin > ----------------- > Java 3D Team > Sun Microsystems Inc. > > > > > >Content-return: allowed > >Date: Mon, 24 Jun 2002 10:07:34 +0200 > >From: "Sch�fer, Peter" <[EMAIL PROTECTED]> > >Subject: RE: [JAVA3D] ModelClip bug ? > >To: 'Kelvin Chung' <[EMAIL PROTECTED]>, "Sch�fer, Peter" > <[EMAIL PROTECTED]> > >Cc: [EMAIL PROTECTED] > >MIME-version: 1.0 > > > > > > > >> -----Original Message----- > >> From: Kelvin Chung [mailto:[EMAIL PROTECTED]] > >> Sent: Freitag, 21.
