Name
beginContour()
Class
PShape
Description
The beginContour() and endContour() methods make it
possible to define shapes with other shapes cut out of them. For
example, the inside of a letter 'O'. These two functions are always
used together, you'll never use one without the other. Between them,
define the geometry you want to create. As you'll see when you run
the example above, the second smaller shape is cut out of the first
larger shape.
The exterior shape and the interior contour must wind in
opposite directions. This means that if the points of the geometry
for the exterior shape are described in a clockwise order, the points
on the interior shape are defined in a counterclockwise order.
Examples
PShape s; void setup() { size(200, 200, P2D); // Make a shape s = createShape(); s.beginShape(); //s.noStroke(); // Exterior part of shape s.vertex(-50,-50); s.vertex(50,-50); s.vertex(50,50); s.vertex(-50,50); // Interior part of shape s.beginContour(); s.vertex(-20,-20); s.vertex(-20,20); s.vertex(20,20); s.vertex(20,-20); s.endContour(); // Finish off shape s.endShape(CLOSE); } void draw() { background(204); translate(width/2, height/2); s.rotate(0.01); shape(s); }
