We've all posted stuff here from books. Hell most algos in games are from books. That is the general idea of Game Programming Gems, Shader Gems, etc, etc.
Nothing is original and it is the free sharing of information and code that grows the industry.
Ahluka not quoting a public site like gamedev IMO is no big deal. It's obvious to me if it's found in several books and sites then the info is probably commonly known as is no longer qualified as original or stealing if you use it. It's obvious the creator of the code did not intend on copyrighting it and was just sharing information.
We are not writing academic posts here with quotes and references and as well Ahluka has demonstrated research and knowledge in this area as well as the ability to adopt complex concepts and use them in his own design.
To me that's called a game programmer and he doesn't need ridiculed by someone like you with a beef that's assinine as yours.
And yet you are the one who has responded to the this thread with an issue that isn't even related to the topic at hand?Are you guys purposely stupid ?
