One of the most important challenges in Computer Graphics is realtime rendering of terrain. This is due to the huge number of polygons used to represent these surfaces. Up to now, several works have appeared that attempt to reduce terrain visualisation time, some of which are based on multiresolution modelling. This method adapts the number of polygons of an object as a function of particular criteria in order to reduce the information that has to be computed for each frame. The ultimate purpose of this work is to compare the most popular multiresolution algorithms to have appeared in recent years, while at the same time examining some of the fundamental concepts underlying realtime terrain visualisation.
