I want to get the new powerbook with the Radeon 9000. My current program uses Nvidia VAR extensions. I was wondering if GL_APPLE_vertex_array_range is the equivalent extension, or if I have to use an ATI specific extension instead ? I found out about the GL_APPLE_vertex_array_range from this web page: http://developer.apple.com/opengl/extensions.html thanks, Nitzan ------------------------- www.geocities.com/nitzanw www.scorchedearth3d.net -------------------------
