Shape internal clipping.
Dec 16th, 2009, 7:19am  
Posted this a few days ago thinking i had an awnser but to no avail.
I was wondering if its possible to have a shape within a shape set as a knockout to the outer shape. like a boolean.

Think of an "O" as the example.

Working with contour plots and the situation arrises consistently,
any ideas on how to extend the beginshape in processing or use pure java? It seems like the generalpath in java would do the trick but not to sure. Probably a bit over my head on this one.

Just posted this solution yesterday somewhere else. you can use breakshape to cutout holes...

size(400,400);
fill(255);
stroke(0);

beginShape();
// outer shape
vertex(100,100);
vertex(300,100);
vertex(300,300);
vertex(100,300);
vertex(100,100);  

breakShape();
//cutout
vertex(150,150);
vertex(150,250);
vertex(250,250);
vertex(250,150);
endShape(CLOSE);

Thank you! I never saw breakshape in the docs. Mods Might want to link that with beginshape in the online reference, though im sure they have better things to do.
