In a number of programs that I have been writing recently I've wanted to draw a semi-opaque "background" using the rect() function in order to fade out everything that I have been drawing in a program. Here's a simple example:
- int l = 20;
- void setup()
- {
- size(800, 400);
- background(255);
- }
- void draw()
- {
- fill(255, 7);
- rect(0, 0, width, height);
- pushMatrix();
- translate(mouseX, mouseY);
- noFill();
- stroke(0);
- rect(-l/2, -l/2, l, l);
- popMatrix();
- }
