really? I found it to be an invaluable source for understanding the mathematics behind some fundamental computer graphics topics. But I'm also bad at math, so the diagrams helped a lot for me to visualize all the calculus discussed. It's "beginner friendly" but for advanced topics, which is a rarity. There's still a huge gap between reading this and then picking up a SIGGRAPH paper to implement, but that's an industry wide issue.

My only reservation was that it updated at a glacial pace for topics I really wanted. I was waiting for volume rendering 4 years ago, and it looks like they started making articles last month. But I can't really complain about updates to completely free resources.

In the reverse, some days ago somebody wrote that also '77777' may be the result as a randomly generated number, think about somebody asking for 'your lucky number?' and all the other people (probabilly thought in/told numbers from 1 to XX), some choose the same numbers and you are the only one answering: 'ma lucky number's 37289!' and all the people around are watching you saying: 'hu?' So saying that a number may be perceived as random ^^ ...may be valid in terms of your topic 'computer-graphics' (for what people see -or even think they do ?!) (-;

Have a nice weekend, regards...
