most basic visualization
Hi all, I'm looking for a most basic visualization all over the internet, but can't find it anywhere! I just need it to do this: http://img221.imageshack.us/img221/5...izationnt9.gif according to the music. Bright white when it's loud and black when it's silent... I have no experience at making visualizations, I would make it myself if i had any idea just How. I need this for a personal graphic project: ) I would really appreciate if someone would link me to any visualization simmilar to it, or maybe already have made one like it and would attach it: )

Thanks
-Lukas

Hello.

This is not tested with actual music, (I made this quickly at work), but it should provide what you are after...

Hey, that's awesome!! Thanks a bunch!! just what I was looking for...: )

but is there a way to make it more "smooth" maybe? it seems to react to each and every beat, so it's very lambent. Depending on the song, if I play a nice slow song it works perfect, but i need it for a metal song, which is fast and loud, so it's all white almost all the time.

Yes, the second one looks very good even alone, with no modifications. I'll use it this way

Is there anyway to make it react to only the bass? (kick drum or kick and bass guitar) it's white all the time for most songs with the current settings.

find your getspec(_,_,) value and change it to something like
getspec(0.2,0.8,0)

Now make it do a 1bit dither like the gif ;)

Thats totally possible. :)

Make an dithery texture with pixels filled in with the right amount of grey, do an additive blend with the flashing screen and use color map, color clip or color modifier to clip the values to 0 if they are not 1.

e.g. consider this simple texture with 4 dithering layers, colors in % for ease of understanding:

[75][00][50][25]
[00][50][25][75]
[50][25][75][00]
[25][75][00][50]

adding a 25% white will only make the pixels with 75% full white, adding 50% will make the pixels with 75% and 50% full white adding 75% will make all the pixels but the 0% ones into full white.

Its not great, infact tbh this is a really crap dithering pattern... but it can be done, at least very badly. :)

Depending on the size of the image used this can be improved to do 12.5% or 6.25% or 3.125% steps etc...





I took it too far didn't I?
