Triangle Flower
by Ira Greenberg.
Using rotate() and triangle() functions generate a pretty
flower. Uncomment the line "// rotate(rot+=radians(spin));"
in the triBlur() function for a nice variation.
Point[]p = new Point[3];
float shift = 1.0;
float fade = 0;
float fillCol = 0;
float rot = 0;
float spin = 0;
void setup(){
size(200, 200);
background(0);
smooth();
fade = 255.0/(width/2.0/shift);
spin = 360.0/(width/2.0/shift);
p[0] = new Point(-width/2, height/2);
p[1] = new Point(width/2, height/2);
p[2] = new Point(0, -height/2);
noStroke();
translate(width/2, height/2);
triBlur();
}
void triBlur(){
fill(fillCol);
fillCol+=fade;
rotate(spin);
// another interesting variation: uncomment the line below
// rotate(rot+=radians(spin));
triangle(p[0].x+=shift, p[0].y-=shift/2, p[1].x-=shift, p[1].y-=shift/2, p[2].x, p[2].y+=shift);
if(p[0].x<0){
// recursive call
triBlur();
}
}
