Hi all 🙂

**The problem:**  
I’m trying to get set of 3 groups of 3 floats that the relationship between them is a representation of equilateral triangle in a limited space (each number 0.0-\>0.1).  
x1,y1,z1 x2,y2,z2, x3,y3,z3

I want those 3 numbers to be randomly generated within those compounds.  
That means the triangle can be any size or angle within the bounding box, but always equilateral.

**Code approach**  
I’m trying to create a PShape in 3d space and rotate it, and then get the new vertex locations. But when I’m using getVertex I keep getting the original vertex locations.

```auto
s = createShape();
  s.beginShape();
  s.rotateX(map(mouseY, 0, width, TWO_PI, 0));

  s.vertex(0, 0, 100);
  s.vertex(100,0, 0);
  s.vertex(0, 100, 0);
  s.endShape(CLOSE);
  
  for (int i = 0; i < s.getVertexCount(); i++) {
    PVector v = s.getVertex(i);
    System.out.println(v.x+" "+v.y);
  }

```

Here v.x and v.y stay the same after rotation, so I assume that getVertex is relative to PShape and not the scene.

Any idea on how I could get the vertex’s coordinates relative to the 3d space/scene?

when you use this without “s.” you can use modelX, modelY, modelZ to get those
