add shapes / replace shapes
Jul 7th, 2008, 12:31am  
Hi there,
this is a basic question i guess and I`m afraid I just didn`t understand how proc works.

void setup(){
 size(300,300, P3D);
}
void draw(){
 int x=int(random(100));
 int y=int(random(100));
 int z=int(random(100));
 fill(1,2,200);
 rect(x, z,y, x+y);
 fill(200,200,10);
 beginShape();
 vertex(x, x,y);
 vertex(z, x,y);
 vertex(z, z,y);
 endShape();
}

This code is just adding one rnd shape to the other.
But in a longer version, the same code structure the shapes get replaced, so that you always see only one shape.

Why is this? How can I change this - so that I have additive shapes?

thanx for help! proc is great...- anyway!

I'm a bit unsure what you mean by add shapes.  Are you adding new vertices to the shape, or drawing new layers on top of the shape?  The problem in your more complex code sounds like you're drawing a new background on top of the shape, replacing the old one.

it was the background!
defined in setup or in draw - that makes the difference!
