p5.js endContour()用法及代碼示例

function setup() { 
  createCanvas(400, 300); 
  textSize(16); 
} 
  
function draw() { 
  clear(); 
  background("green"); 
  text("The inside of the letter is cut out"+ 
       " using a countour", 10, 20); 
  
  // Starting the shape 
  // using beginShape() 
  beginShape(); 
  
  // Specifying all the vertices 
  // of the exterior shape 
  vertex(40, 240); 
  vertex(100, 50); 
  vertex(130, 50); 
  vertex(200, 240); 
  vertex(160, 240); 
  vertex(140, 160); 
  vertex(100, 160); 
  vertex(75, 240); 
  
  // Starting a contour 
  beginContour(); 
  
  // Specifying all the vertices 
  // of the interior shape 
  // in counter-clockwise order 
  vertex(130, 135); 
  vertex(115, 90); 
  vertex(105, 135); 
  
  // Ending the contour 
  // using endContour() 
  endContour(); 
  
  // Ending the shape 
  endShape(CLOSE);
