Processing 畫三角形

1. 邊緣上色：
   size(600,600,P3D);
   background(255);
   beginShape(TRIANGLE);
     stroke(255,0,0);vertex(300,100);
     stroke(255,255,0);vertex(500,500);
     stroke(0,0,255);vertex(100,500);
   endShape();
   
2. 填滿上色：
   size(600,600,P3D);
   background(255);
   beginShape(TRIANGLE);
     fill(255,0,0);vertex(300,100);//顏色填滿
     fill(255,255,0);vertex(500,500);//顏色填滿
     fill(0,0,255);vertex(100,500);//顏色填滿
   endShape();
   
3. 雙三角形重疊
   void setup()
   {size(600,600,P3D);
   }
   void draw()
   {
   background(255);
   beginShape(TRIANGLE);
   beginShape(TRIANGLE);
   fill(255,0,0);vertex(100,100,0);
   fill(255,0,255);vertex(100,500,100);
   fill(255,255,0);vertex(500,500,0);
   endShape();
   beginShape(TRIANGLE);
   fill(0,255,0);vertex(500,100,0);
   fill(0,255,255);vertex(500,500,100);
   fill(255,255,0);vertex(100,500,0);
   endShape();
   }
