public void exportMesh(String fileName){
  // export an obj file, change to X3DExport for x3d
  MeshExport output = (MeshExport) createGraphics(10, 10, "nervoussystem.obj.OBJExport", fileName + ".obj");

// THE DRAW METHOD IS LIKE THAT:
// (draws all vertices using LINE_STRIP to a provided PGraphics object)
public void draw(PGraphics pg){

  pushTransform(pg);
  //draw all vertices

  pg.beginShape(POINTS);
  for (int i = 0; i < vertices.size();i++){

    pg.vertex(p.x, p.y, p.z);
  }
  pg.endShape();
