No. OpenGL is hardware accellerated on all modern graphics cards and that hardware runs the same speed for 3D and 2D graphics. If there were a 2D-only API, it wouldn't be hardware accellerated and even if it were, it would just leave some of the 3D hardware unused. It wouldn't run any faster than OpenGL. > This is in the context of development of a viewer application for > display of semi conductor layout geometry containing millions of > polygons and all present on a 2D plane. Perfectly applicable to OpenGL rendering. You'll likely have lots of layers of geometry - and rendering that using the Z coordinate as the layer number would make a lot of sense. This is a case where using the 3D capability of OpenGL to do 2D rendering makes a lot of sense. ---- Steve Baker (817)619-2657 (Vox/Vox-Mail) L3Com/Link Simulation & Training (817)619-2466 (Fax) Work: sjbaker@link.com http://www.link.com Home: sjbaker1@airmail.net http://www.sjbaker.org From sinkam@mail.utk.ru Tue Jan 14 00:26:05 2003 Received: with ECARTIS (v1.0.0; list ogl-sample); Tue, 14 Jan 2003 00:26:09 -0800 (PST) Received: from ns.utk.ru ([212.220.44.1]) by oss.sgi.com (8.12.5/8.12.5) with SMTP id h0E8Q23v018498 for ; Tue, 14 Jan 2003 00:26:04 -0800 Received: from localhost.localdomain (IDENT:sinkam@vd55.utk.ru [81.91.33.55]) by ns.utk.ru (8.9.3/8.9.3) with SMTP id NAA15887 for ; Tue, 14 Jan 2003 13:32:06 +0500 (ESK) From: sinkam Date: Tue, 14 Jan 2003 12:30:46 +0500 X-Mailer: KMail [version 1.1.99] Content-Type: text/plain; charset="koi8r" To: ogl-sample@oss.sgi.com Subject: development group MIME-Version: 1.0 Message-Id: <03011412304606.00767@localhost.localdomain> Content-Transfer-Encoding: 8bit X-archive-position: 15 X-ecartis-version: Ecartis v1.0.0 Sender: ogl-sample-bounce@oss.sgi.com Errors-to: ogl-sample-bounce@oss.sgi.com X-original-sender: sinkam@mail.utk.ru Precedence: bulk X-list: ogl-sample Dear sirs, could you inform me on email address of OpenGL development group.
