NEW ARTICLE: "QUADTREE"

Kyle Shouviller has written a nice article on quadtrees with also comes with source code included.

From Kyle's article: "... Imagine a game like Pong, except with a rotating triangular ball. This ball needs to have perfect collision detection with the paddles, which means if any part of the triangle intersects with the paddle, there is a collision. You can’t just do simple radial collision detection, nor can you do rectangle collision detection, because the triangle might not actually be colliding for some collisions detected in those cases. However, performing the triangle-to-paddle collision detection can be expensive to do every frame (I know, not that expensive – but imagine 200 balls with 30 players around a big field with balls also colliding with each other, or something like that). So what are you to do? ...".

NEW FF2 TRAILER

Almost every comic fan in the world is paying attention to the spiderman 3 movie -now in theaters- because of the appearance of one of the fiercest foes ever: Venom.

However, and despite the fact that I haven't gone the cinema yet to watch the above-mentioned movie, I'm particularly more excited with the Fantastic Four's sequel. Why? First, if the Silver Surfer is in it, it should also imply that "Gah Lak Tus" is. And second, because of this new trailer.

I'm not going to argue why I prefer more FF over SP series of movies, at least for now, but in short, I'm not happy with the way Peter Parker's life is being presented/plotted. Maybe in a later post I could explain the reasons behind my sentiment, but for now, I'd only say the the part of the script that deals with PP should be improved.

Anyway, the new FF trailer rocks!

[Btw, an ironman movie is coming ...]
