I started using Processing three days ago. I am using Processing to capture the motion of a MPU6050-driven IMU sensor. I need a human form (or something that resembles human) to represent the data output of the IMU sensor.

Something like this: [https://www.youtube.com/watch?v=LlhV-6v6uEY](https://www.youtube.com/watch?v=LlhV-6v6uEY) is good enough!

Help is 100% appreciated !!!

The code I have is this:  
// draw main body in red  
fill(255, 0, 0, 200);  
box(50, 25, 130);

```
// draw sphere representing head in red
fill(255, 0, 0, 200);
pushMatrix();
translate(0, 0, -120);
rotateX(PI/2);
sphere(20);
popMatrix();

// draw wings and tail fin in green
fill(0, 255, 0, 200);
beginShape(TRIANGLES);
vertex(-100, 2, 30); vertex(0, 2, -80); vertex(100, 2, 30); // wing top layer
vertex(-100, -2, 30); vertex(0, -2, -80); vertex(100, -2, 30); // wing bottom layer
vertex(-2, 0, 98); vertex(-2, -30, 98); vertex(-2, 0, 70); // tail left layer
vertex( 2, 0, 98); vertex( 2, -30, 98); vertex( 2, 0, 70); // tail right layer
endShape();
beginShape(QUADS);
vertex(-100, 2, 30); vertex(-100, -2, 30); vertex( 0, -2, -80); vertex( 0, 2, -80);
vertex( 100, 2, 30); vertex( 100, -2, 30); vertex( 0, -2, -80); vertex( 0, 2, -80);
vertex(-100, 2, 30); vertex(-100, -2, 30); vertex(100, -2, 30); vertex(100, 2, 30);
vertex(-2, 0, 98); vertex(2, 0, 98); vertex(2, -30, 98); vertex(-2, -30, 98);
vertex(-2, 0, 98); vertex(2, 0, 98); vertex(2, 0, 70); vertex(-2, 0, 70);
vertex(-2, -30, 98); vertex(2, -30, 98); vertex(2, 0, 70); vertex(-2, 0, 70);
endShape();

popMatrix();

```

sorry, i need to see it first,  
so i play little bit ( using my PTZ )

```auto

  stroke(0,0,200); //noStroke(); // test visibility
  pushMatrix();
  translate(0, 0, -120);
  rotateX(PI/2);
  sphere(20);
  popMatrix();

  // draw wings and tail fin in green
  pushMatrix();

looks good, now what was the question?  
need 2 arms? made by 2 or 3 3D elements?
