James的圖學筆記Week14

光柵化

Part1.繪製三角形

mode1.描邊
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();

mode2.填滿
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();

mode3.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();
}
