HDR without shaders - It can be done the lamers way

[Nitrogen]

I used a similar glow technique in my Chrome plugin...

You might want to blur the texture before rendering it back to the screen...

To blur it, you render the texture twice back onto the *same* texture you rendering, first with a shift to the left, then again with a shift to the right
(with transparency of course)

Then you take the updated texture and render it back onto the same texture again, this time shifting it up and down.

If you do this enough times, it will make a VERY nice blurred glow.

I was thinking to blur it pixel by pixel, but I think rendering it up/down would be better. (don't know if its faster).

Thanx for the idea.

It should definitely be faster... The more work you offload onto the GPU the better.

Just be sure to add options for those features that some graphics cards might not handle so well...

I remember not being able to play some games on my old laptop bcause it was so old. The CPU was up to spec, but the graphics card just sucked. Sort of an extreme case since mine practically didn't have *any* 3D accelleration features whatsoever, but still maybe some players might not have pixel shaders 2.0 and instead have only 1.0, etc...

*shrug* It's just nice to be able to still play even though your graphics settings are set a bit lower to compensate.


BTW you killed your really BIG image.

[NecroDOME]

No, I dind't killed my image, my server was down. Upgraded to Windows Server 2003... (and within 10 min I got my first BSOD)

Hm.., are you going to archive something alike Tron 2.0 rendering?

Comming back to this part: just tested it and its's possible

[NecroDOME]

So I finnaly blured the texture. We got a better result, but it runs @ 3-4 FPS




I think I need to go with Nitrogen's approach. Render and shifting it...

UPDATE:

Glow in the dark


(as you can see, I did a bit of red-tron-glow on the players ship)

Woo hoo! Tron-Glow rocks!
