After a couple of months of inactivity, I am pleased to say that my HOpenGL Tutorial was heavily updated in the last days. I've concluded all basic lessons, and hope to do the same with the intermediate ones soon. You can visit the tutorial at: http://www.cin.ufpe.br/~haskell/hopengl/ Any suggestions, comments or corrections are welcome. Thanks, Andre W B Furtado Recife, Brazil
