Hey Everyone

I'm all noob to this whole processing thing so i'm sorry if this is question is a little ridiculous question but i could really use a little help. So thank you very much in advance.


I got all theese vertex lines rotating around but i only want to see the part that is within the static ellipse area. I realise that i could do this by making a white rectangle with a hole in it, as a mask, but then i get a white area in my output pdf. So i think i need somekind of cutting where the vertex intersects with the ellipse or?


I hope this gives a description of what i'm looking for:



My code is this:

1. void setup() {
   
   size(1000, 1000);
   }
   
   void draw() {
      
   noFill();
   
   background(255);
   
   ellipse(500,500,900,900);
   
   translate(500, 335);
   
   strokeWeight(3);
   strokeJoin(ROUND);
   
   
   rotate(radians(frameCount));
   
      beginShape();
     vertex(523,203);
     vertex(457,396);
     vertex(393,348);
     vertex(320,358);
     vertex(448,266);
     vertex(456,206);
     endShape();
   
     beginShape();
     vertex(316,211);
     vertex(360,225);
     endShape();
   
     beginShape();
     vertex(372,158);
     vertex(294,158);
     vertex(276,224);
     endShape();
   
     beginShape();
     vertex(187,245);
     vertex(276,224);
     vertex(305,222);
     vertex(282,241);
     vertex(196,287);
     endShape();
   
     beginShape();
     vertex(284,274);
     vertex(300,286);
     vertex(306,296);
     vertex(311,313);
     vertex(310,329);
     endShape();
   
     beginShape();
     vertex(306,296);
     vertex(256,336);
     endShape();
   
     beginShape();
     vertex(260,430);
     vertex(255,389);
     vertex(208,363);
     vertex(229,331);
     vertex(256,336);
     vertex(265,371);
     vertex(302,377);
     endShape();
   
     beginShape();
     vertex(27,429);
     vertex(49,411);
     endShape();
   
     beginShape();
     vertex(11,309);
     vertex(31,344);
     vertex(120,355);
     endShape();
   
     beginShape();
     vertex(26,289);
     vertex(41,313);
     vertex(129,326);
     endShape();
   
     beginShape();
     vertex(-94,258);
     vertex(-27,235);
     vertex(25,206);
     vertex(61,143);
     endShape();
   }
