In previous sections it was shown that the visibility computations can significantly speedup the visualization process. Furthermore, the information about restrictions in visibility can be applied to some other tasks, such as multi-user distributed virtual reality or photo-realistic visualization by the radiosity method.
Future work could be focused on algorithms, which take an advantage of both of the currently popular approaches - potentially visible sets and the ``online'' obscuration culling methods. The aim is to design algorithms less sensitive to the type of the MVE with a reasonable efficiency and possible adaptive balance between the preprocessing and calculations performed on the fly.
