After the establishment of the
BSP tree, we can travel all nodes in the scene conveniently
such that it is easy to render and make collision detection.
To achieve an effective scene editing and access, we use the
MESH scene structure which can be translated from X3D.
This approach provides an entity template which can make
user customized some operations. By this way, the limited
memory storage can be saved effectively and the speed of
the algorithm can be improved greatly. In addition, we can
get all the information related to certain entity by this
typical MESH scene structure.
