It started as a christmas gift that would express myself and ofcourse keep me from following everybody else to the local shop and spend my money on something  made by others.

There is no executable this time, as i don’t know if i can spread the music, still, nobody can stop me  (for the moment) from giving you a video. So here it is, Float.

came to work, daft punk was playing, i was browsing my hd and opening projects. at some moment i opened this nebulado project which never satisfied me before and for my surprise it reacted quite nice to the track that was playing (Daft Punk – Harder, Better, Faster, Stronger), so i fired up Fraps and captured a video.

a smoother version was created which starts slower and builds up progressively, but i prefer this one

track by daft punk.

The big and awesome city that i can’t find the name. So i thought to myself, i should try and play the architect myself… Here’s some results:

So i started working on both pieces together and came up with what you’re about to see in the videos below.

The scene is rendered using a per-pixel phong lighting model + wrap lighting, a fast trick to approximate subsurface scattering. More information available in  the GPU Gems book.

I have used lee byron‘s mesh library for the 2D voronoi mesh generation and loaded it up my framework to generate a 3D heightmap mesh.   I’ve reduced the effect to almost zero here, just because i think it looks much better flat in this particular scene.

Done using processing + java.

fixed exporting problems (something about minim effects and fullscreen, still a mistery).

new features:

. handle all generators/samples and the activator by click and drag.
. set activation range as global or individually by a toggle button on the menu.
. change frequency/amplitude per generator.
. physics got a little better, not realistic but that wasn’t the point anyway.

it was fun to make. enjoy!

This became a visual for a sequencer idea i had. i was playing with Tactu5 and ended up creating ribbons and doing some synth and this is a first acceptable result.. for now=)

I was playing with a sequencer called Tactu5 and i ended up creating a visual effect to see the how midi notes and Minim synth worked together. I’ve also added some LFO’s to modulate the waves, but thats a different story. This is a screenie of what i came up with.

A minimal look with a centered alien ball that grows tentacles as notes play and based on their frequency. the up-growing are based on a pinknoise. Well it’s still just an idea but it might turn into something good.

We shall wait and see.
