How to...visualizer

vvvv beta general
1

Hi everyone.
I’m a really vvvv beginner starting to make experiments for a multimedia project in progress.

Now I’m playing around an idea to make a sort of music visualizer. I’d like to understand how to realize a basic visualizer effect like the one in this page http://www.upgradesource.com/gforcehd/screenshots-10.gif or in this one http://desktop.google.com/plugins/images/gforce.gif.

The problem is not the oscillating line but the “blur trail” effect.

Any explanation or examples will be really appreciated.

Thank you.

Have a look at Gaussian Blur shader, or you can also add a Queue (Value) in your oscillator.

Cheers,

Thanks artrobota,
I’ve already tried blur shader and is not what I mean.
I’ll try for the queue.
Maybe the methods descripted here or here can be useful…?

Have a look for example at this image…

have a look at tonfilms Music3d Patch, play with the camera, and try combining it with the bloom shader, and you should get much more beautiful results than the images you posted :)

Hi,

are you looking for something like that ?
(see attached)

and yes have a look at that tomfilm’s patch.

p.s : can someone delete the first attached file ?

you might also think about feeding back a distorted render-output as background texture.

sorry for the quick & dirty, fit-inducing patch, but you’ll get the idea (includes @sanch DeformByTexture - shader):

Thanks boys, I’m studying your patches…

check the motionblur patch from tonfilm too and i’m sure you can use the iir filter (textures) module from kalle too.

havvvve fun
