I'm quite interested in games programming in general (in fact that was I learnt to program in the first place) and have recently been doing a bit of research on some of my old ideas. One of them includes a procedural terrain generator. The problem is after a little bit of searching it appears that the obvious method of going about the task is patented(!). http://v3.espacenet.com/publication...C=A&FT=D&date=20070510&DB=EPODOC&locale=en_gb How are you supposed to work around these things? It is absolutely ridiculous that someone can patent an obvious and well known technique such as this. In fact one of the rules for UK patents is that you can't patent something which is obvious to someone with good knowledge of the field. Now don't get me wrong, I'm not claiming to have good knowledge of the field but if I were to do some form of real time terrain generation it would be pretty obvious how to do it. So what to do? How do commercial products get around these patents? Surely these can't really be enforced? Call me an idealist (communist / liberal scum / whatever) but I fail to see how giving exclusive use of certain technological processes to corporations helps mankind.
