Song -> aphex twin - 4

i used a perlin noise class which can be found here :
flipcode.com/archives/Perlin_Noise_Class.shtml

and some of this is still adapted from a robert hodgin source which can be found here flight404.com/blog/?p=113

    great work. I used the same perlin noise class.
  • Rui Madeira plus 1 year ago
    Thanks :) i'm not sure, but i think it was you who mentioned it in the OF forum, and it was because of that that i decided to give it a try
  • moka 1 year ago
    yes it was me :)

    btw is this still using any of your previous boids experiments?
  • Rui Madeira plus 1 year ago
    yes it is. thats pretty much the same boids but i made a sphere flow field, where perlin noise alters the rotation of their position. :)

    like the small detail with the rays and little bubbles floating up.
    good work!

    Absolutely amazing!

    Are they rays some fancy OpenGL lighting? ... or are they sort of 'faked' like flickr.com/photos/nikrowell/3165032523/
  • Rui Madeira plus 6 months ago
    Hi, thanks :)

    the rays are from a sphere in the background that is being deformed according to sound analysis (spikes come out of it), making it almost transparent and using additive blend makes it look like that :)

    Oh man, I like this a lot!! How did you create the spherical forces?
  • Rui Madeira plus 5 months ago
    im using 3d polar coordinates to position the ribbons in a spherical way. The polar coordinates are calculated using 2 angles (theta and phi) and a radius. Then i'm animating these parameters using perlin noise as well as the fft values from the music. :)

    I wish I could see this.. it never seems to play here, for some reason (I've been getting that a lot on Vimeo, annoyingly)...

    thats strange, i can play it without any problem. i dont have it anywhere else online but if you really want to see it you can try downloading the file.

    Re. non-playing movie:
    Downloading it now. I'd forgotten about that option.

    Very nice! I like how the spherical version of a noisefield works.
