Missing functions

17 July 2008 - 08:21 PM

The "driver" for the Intel 965 GM "graphics" "adapter" claims to suport OpenGL version 1.5 (how current!) but it "forgets" to export any of the corresponding functions. This means no buffer objects (see example below) and no occlusion queries. Way to go, Intel!
Traceback (most recent call last):

Links from the NeHe page

27 February 2008 - 02:10 AM

The links in the left sidebar of nehe.gamedev.net might perhaps be cleaned up a little; many point to important, current sites (like opengl.org or gamedev.net) or to old but useful material (like flipcode.com), but a large portion should be removed. Just dead: http://www.3rdlife.net/ http://www.exsanity.freeola.com/projects.html http://www.falloutsoftware.com/programming.php4 http://glazsd.tripod.com/ http://www.razorgamesuk.com/news.php?rt=1 http://perso.wanadoo.fr/perois/OpenGL_Tutorial.html http://www.x-tutorials.de/ Host not found, parked domains, "under construction" etc. Obsolete, unmaintained, useless: http://siggi.vefurinn.is/ A blog of personal stuff, in Icelandic, updated in May 2007. http://www.watotron.com/ Almost empty, updated in 2005. http://csgl.sourceforge.net/ Project closed and reincarnated: http://www.taoframework.com/ http://www.cpp-home.com/ Updated in 2005, broken Perl scripts. http://www.kref6.prv.pl/ Project closed since 2005. http://www.boolatgames.com/ A game development company that doesn't say anything interesting about their 3D graphics. http://www.slamsoftware.com/ Updated in 2003. http://www.everdusk.be/ Inactive, almost empty blog/personal page. Questionable: http://www.pzeta.org/opengl/ Has moved slightly from the linked position; the problem is the combination of very sparse OpenGL content from 2 years ago, a home page with a curious assortment of subjects, and a "forum for men" full of spam. http://www.bosrup.com/web/overlib/ Nothing bad with the software or the site, but what is the relevance to OpenGL programming of a javascript library to make popups?
