Not all opengl driver support detail texture either, please check the textureDetailAvailable flag return by Canvas3D public final Map queryProperties() Thanks. - Kelvin --------------- Java 3D Team Sun Microsystems Inc. >----- Original Message ----- >From: Kelvin Chung <[EMAIL PROTECTED]> >To: <[EMAIL PROTECTED]> >Sent: Monday, January 14, 2002 4:45 PM >Subject: Re: [JAVA3D] Detail texture > > >>Delivered-To: [EMAIL PROTECTED] >>MIME-Version: 1.0 >>Date: Mon, 14 Jan 2002 07:25:24 -0500 >>From: "Yazel, David J." <[EMAIL PROTECTED]> >>Subject: Re: [JAVA3D] Detail texture >>To: [EMAIL PROTECTED] >> >>I fooled around with this new feature for some time last night and could >get >>no results.
