translate method
Translate the geometry by x,y,z. This is typically done as a one time operation,
and not during a loop. Use position for typical real-time
mesh translation.
Implementation
BufferGeometry translate(double x, double y, double z) {
  // translate geometry
  _bufferGeometrym1.makeTranslation(x, y, z);
  applyMatrix4(_bufferGeometrym1);
  return this;
}
