i know from  
[https://processing.org/reference/shape\_.html](https://processing.org/reference/shape_.html)  
shape(s)  
shape(s, x, y)  
shape(s, a, b, c, d)  
and  
s.translate(x, y)

also it is possible to use in P3D  
s.translate(x, y, z)  
what is additive,  
so

```auto
  s.resetMatrix();
  s.translate(sx,sy,sz);
  shape(s);

```

same as

```auto
  translate(sx,sy,sz);
  shape(s);

```

my question is, why there is no 3D position ( or i miss something )

```auto
  shape(s,sx,sy,sz);

```

You can see the existing shape methods here:

> <https://github.com/processing/processing/blob/processing-0269-3.5.3/core/src/processing/core/PGraphics.java>

There is a:

```auto
  // TODO unapproved
  protected void shape(PShape shape, float x, float y, float z) {
    showMissingWarning("shape");
  }

```

From the examples in the source I made my own:

```auto
  shape(s, sx, sy, sz);
  }

 public void shape(PShape shape, float x, float y, float z) 
    {
    if (shape.isVisible())
      {
      flush();
      pushMatrix();
      translate(x, y, z);
      shape(shape);
      popMatrix();
      }
    }

```

In your example the translate(sx,sy,sz); does the same as the method would.

thanks, so it is “in work” already and i not need to open a “issue”.
