It's truely amazing just how much historic information you can find online these days if you want to - that's Internet historc data; by contrast it can be very hard to look back prior to the days of The Web in some areas - you just try putting together a table of London to Manchester train fares and ....

3148 - OpenGL / C / C++ - an example to get you started

A Computer Graphics application in C / C++ - that's the coding that one of my delegates is going to be doing for her "real work" after this week's course, and I found myself looking back to old times - when I used (amongst other things) to subcontract to Silicon Graphics to present courses on their ....
