Hi! I found this picture the other day and I thought it'd be nice to do some Processing applet similar to that. I defined a class for a grid of circles, and assigned a color, number, diameter and speed of rotation to each instance. The problem I find is that the colors do not blend as in the pic, as I thought they would by using the alpha function. Any ideas? Thanks!
PD: I don't know if it's necessary, but I'll just leave the code here in case someone is interested.
// cmyk! (16/02/12)
Malla[] capa; int lado = 400; int nc = 3; // número de capas
void setup() { size(600, 600); smooth(); noStroke(); capa = new Malla[nc]; capa[0] = new Malla(6, 40, 5, 255, 255, 0); capa[1] = new Malla(6, 60, 3, 0, 255, 255); capa[2] = new Malla(6, 50, -2, 255, 0, 255); }
void draw() { translate(300, 300); background(230); for (int i=0; i < capa.length; i++) { capa[i].paso(); } }
class Malla {
int n, d, v, r, g, b; float angle = 0;
Malla(int N, int D, int V, int R, int G, int B) { n = N; // número de círculos por lado d = D; // diámetro v = V; // velocidad r = R; // color en RGB g = G; b = B; }
