Hi Paul Very nice, had a good read and it reads very well, great job
Did not see any issues, but perhaps when your talking about light sources and the number available(p66) that a little caveat that using multiple light sources can potentially impact performance in the same way its mentioned for GL_NORMALIZE, just a thought nothing more :) Also perhaps if your going to expand on lighting in later chapters you might want to talk about Spot lights and how you need tessellation etc for them to work in OpenGL, this always seems to catch lot of people out when they try use spot lights as spot lights ;) I have an image http://www.vis-sim.com/imgdp/vp_lights_ex2.jpg that I put together for the when I 'm teaching Creator and Vega/VegaPrime, your free to use this if you wanted, I can send you the original file and OpenFlight file that shows this if you like Best Regards Gordon __________________________________________________________ Gordon Tomlinson Email : gordon.tomlinson @ overwatch.com YIM/AIM: Gordon3dBrit MSN IM : Gordon3dBrit @ 3dSceneGraph.com __________________________________________________________ Telephone (Cell): (+1) 214-477-8914 Telephone (Work): (+1) 703-437-7651 "Self defence is not a function of learning tricks but is a function of how quickly and intensely one can arouse one's instinct for survival" - Master Tambo Tetsura -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Paul Martz Sent: Monday, April 23, 2007 1:54 PM To: 'osg users' Subject: [osg-users] Quick Start Guide feedback request Hi folks -- I'd like to produce a "final" revision of the Quick Start Guide by mid next month.
