計圖筆記week14

畫三角形:

程式碼:

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();

填滿圖案

size(600,600,P3D);

background(255);

beginShape(TRIANGLE);

  fill(255,0,0);vertex(300,100);

  fill(255,255,0);vertex(500,500);

  fill(0,0,255);vertex(100,500);

endShape();

重疊三角形

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();
