I'm working on another demo.. this time i'm playing with post rendering effects, like blur, hdr and glow :) this demo features a simple full screen glow on a nice sky (animated via shader with atmosphere scattering) and a simple terrain. In a nutshell i render the scene in a fbo, darken the resulting texture and then blur it. Finally i add the original image and get the glowing effect :) I've tested it on a Gefo 6600gt and works fine (~90fps), but i don't know if there are problems on ati cards.. here's a screen and here's the demo bin Hope you like it :) EDIT: i've added a terrain shader that blends two textures according to the height and computes a bit of lighting :) [Edited by - b3rs3rk on January 10, 2006 6:37:57 AM]

Your blur filter appears to be somewhat off, it's got a strange diagonal bias to it and obvious banding between the different samples. How are you blurring your glow texture?

I agree with the above post.

It looks great, but is a tad blurry. You might need to tweak things a little more. It adds alot of deptht to the game, though!

Edit: you're link is broken, BTW.

Hi,

I have some problems running the demo:

All is dark, and the terrain and sky is not correctly showing up:
Free Image Hosting at www.ImageShack.us

Hardware: ATI Radeon 9800 Pro, AMD 64 3200+, 1GB Ram
Driver: Catalyst 5.12

The Log contains no errors, only loaded ...

Hope you can fix it somehow, ( I want to see it live ;) )

Bye,

Marc
