Strange little demo this. Completely pointless, but shows off a camera control technique I was playing with. Music by Mr Scarab.



Zip attached.

I saw the screenshot, and had to DL. Good effect. I was curious though, did the static respond to the music? It was hard to tell if it did or not.

whoa, that was awesome, it was a cool effect for opening credits, I think I will want a similar music intro but with rain instead of popcorn, then a dark cyberpunk alleyway leading onto a street will fade in as the camera moves about, then it will go to the original intro. I might ask you for help on this later

some technical info:

Static responds to the camera movement (slightly) and is made up of 3 ghosted plains.

'Popcorn' is made up of 1500 textured, transparent plains - all being individually rotated each frame.

Camera movements achieved by first recording a sequence of movements from the mouse, and then 'playing them back' in the form of a camera position.

Cam always facing same direction to give nice effect.

I think I might develope this a little bit further - maybe with a nice retro text-scroller.

If anyone wants the source (for the 'mouse position recorder', and the main demo), e-mail me.

Wow I'm very impressed. 1500 plains? Sheesh, I'd love to see how it runs on my old computer. Very good work, let me know what else you come up with.

Nice I'd love to see the way you did the grainy distortion effect. I have a few ideas, but they all seem like they'd be too slow. For my current project ROBOI, it would be cool to have an effect like that during the level intros.

The grainy effect is accomplished by creating three 'noise' textures. Then, cycle between the three textures on a plain (or use three plains and swap them over) - ghost the plains so you can see through them. Make sure the plains are close to the camera so they cover the whole screen. Simple.

I'm sure there are better ways of doing similar effects with shaders, but I'm still a bit 'old school' for that.

My next demo 'Red' improves on the process, and is currently looking VERY nice! (I will try and get it finished tonight).

Here is a little sneak preview:
