Abstract: Fast real-time rendering problems of extra large terrain in VR are studied. A new method of terrain modeling is proposed. This method divides the whole extra large terrain into many smaller tiles, and splices the original terrain according to certain rules with these tiles. The VR program only needs dynamic loading the tiles data which can be seen by client and unloading those which cannot be seen when roaming. This method resolves the memory problem effectively and improves rendering efficiency.
