Here’s the old crappy bloom effect I had implemented long time ago…

And here’s one that uses exactly the same technique as in C&C: Twilight !

Looks much better, right?
At first it might just look like I increased blurring radius, but that’s not the same since it wouldn’t give this kind of beautiful effect.

Here’s a small guide I made on how to achieve that effect :

1. You first downsample the backbuffer into two images, lets call them alpha and beta.
2. Alpha is the downsampled ( 1/4th size ) version of the backbuffer.
3. Beta is the downsampled ( 1/4th size ) version of Alpha.
4. We blur Beta, and then blend it with Alpha.
5. Once we did that, we blur Alpha.
6. Then we apply that to the backbuffer

And we’re done !

Unfortunately I have some exams I got to take care of so the progress will once again slow down.
