Hi I’m working with the processing library for Java, and are having some issues giving my shapes a texture, right now, the texture isn’t showing. I hope some of you guys might have an idea, of what I’m doing wrong.

IDE is eclipse.

Heres my code:

```auto
public class View extends PApplet {
     PImage img;
     PShape myShape;

     public void setup() {
         img = loadImage("assets\\images\\test.jpg");
     }

     public void settings() {
        size(displayHeight*3>>2, displayHeight*3>>2);
     }

     public void draw() {
         background(175);

         myShape = createShape();
         textureMode(NORMAL);
         myShape.beginShape();
         myShape.texture(img);
         myShape.vertex(0, 0, 0, 0);
         myShape.vertex(100, 0, 1, 0);
         myShape.vertex(100, 100, 1, 1);
         myShape.vertex(0, 100, 0, 1);
         myShape.endShape(CLOSE);
         shape(myShape);
     }
 }

```

Hi! Welcome to the forum!

It seems the problem is that you need to use P3D for texture mapping

```auto
        size(displayHeight*3>>2, displayHeight*3>>2,P3D);

```

I learned that by dropping `myShape` and drew in immediate mode - in that case there is an error that `vertex(x,y,u,v)` is not available in this renderer.

also `PShape` is not meant to be instantiated in `draw` loop. Although you can do it, the performance is not as good, so you should move it to `setup` or use the immediate mode if you want to constantly change vertex coordinates etc.

Thank you so much! I had previously tried with P3D, but it gave me an error, so I anbandoned it. But I just now found out, that I had only imported the core.jar, but was missing both jogl and gluegen jars, after importing those, it seems to work as intended! 😃

(as to instantiating it in the draw loop, it was only for testing purposes 🙂 )
