« Posted 2007-07-20 11:27:47 »

Here is a new tech demo that I have been working on in LWJGL. The scene is rendered into a float buffer, and the component that is > 1 is gaussian blurred and redisplayed over the top. The bloom is slightly 'exaggerated' in this demo... but what's the point of a bloom tech demo if you can't make it look like gears of war.

The demo requires OpenGL 2.0, Non power of 2 textures and float texture support:

Fine here on XP (Java 6.02), some good Nvidia card from 3 years ago.

Vista Ultimate?  Have you ripped out your hair yet?

Oh yeah, worked for me as well (OS X 10.4.10, 2GB RAM, 256MB X1600)

Thank you for giving it a run everybody.

OleR: That should not be happening at all and I can't explain it. Try clearing your webstart cache and trying again, it's like webstart isn't using the right classpath...

Moogie: I have that same setup on my hope PC and it works. Are you using recent drivers? There shouldn't be a black screen though... :S very odd I have noticed the same thing happening on the new macbook pro's (nvidia cards).... maybe there is an issue there I will have to have a look into.

In other news, I have also got tone mapping working in a more recent build. I might upload it tonight when I get home from the office.

Thanks again!

Same problem here, Win XP SP2 and a 7800 GS I think

I would say "obviously something wrong with your libraries / binaries / config" because webstart cache by design should have no effect on this...

Ditto here... with recent ATi drivers.

I'm 100% sure these cards support NPOT-textures, I think you're just using an OpenGL-extension that's only implemented in nVidia drivers. You should try to find the ATi alternative.

This looks really sweet, great job man.

However, it doesn't work on my Radeon X1600Pro.  I'm using the latest Omega drivers.

tried again. Screen was black for ages, and your mouse capturing is **** - it went haywire so I had to kill the JVM.

I very very strongly suggest you don't capture the mouse however it is you're doing it, it's just nasty.
