X3D (Extensible 3D) is a standard description language for describing 3D scenes on the web environment and can be used to establish 3DVR e-commerce systems, such as virtual shopping malls. However, due to the CPU and memory limitations of mobile devices, the 3DVR e-commerce systems described by using X3D scene language cannot be used on mobile devices. This limitation delays the growth of 3DVR ...
