This is how Project Talaus uses the shape bank to cache time critical data.

3DTask.h

NL3D::UDriver &driver() const
{
  nlassert(driver_instance);
  return *driver_instance;
}
NL3D::UShapeBank &shapeBank() const
{
  nlassert(shape_bank_instance);
  return *shape_bank_instance;
}

3DTask.cpp

if(driver_name == "DirectX")
{
  driver_instance = NL3D::UDriver::createDriver(icon, true);
}
else if (driver_name == "OpenGL")
{
  driver_instance = NL3D::UDriver::createDriver(icon, false);
}
else
{
  nlerror("%s is an unknown driver name please use DirectX or OpenGL.", driver_name);
}
shape_bank_instance = driver_instance->getShapeBank();
