ProcessingJS不以3D模式绘制图像

Question

I am trying to draw an image to canvas using ProcessingJS. It works perfectly in 2D mode but not in 3D. The code looks the following:

PImage img;

void setup(){
    size(600, 400, OPENGL);
    strokeWeight(1);
    noFill();
    frameRate(60);
    imageMode(CENTER);
    img = loadImage("img.png");
}

void draw(){      

     image(img, 20, 20);

}

Any ideas what might cause the problem?

If you're using a version of Processing.js that is older than 1.3.0, then this link might explain why it doesn't work:

Otherwise, you might try mapping your image as a texture on a polygon like in this example:
