sorry for being silent for such a long time (again...) but I was busy with finalizing my studies. In last few days I finished them with A+ grade with my thesis being about 3D engine programming ("Design and implementation of a 3D framework for games and visualizations" to be more precise). If no one at my university will have anything against it, I will share it of course (probably first translating it to English as it was written in Polish). Nothing special in it, just what almost everyone knows but maybe it will turn out to be useful for beginners.
I've also just finished writing my HDR tutorial, which you can find here. I hope anyone interested in photography will find it useful as it should help you get the look of photos similar to the one on the left.
I should be back to nGENE programming in a week or two.
