Walking on the Edge of the Well of the Itza: The Reconstruction of an Ancient Maya Metropolis in the Centre of the Northern Yucatan

F. Pittarello


Abstract

The three-d reconstruction of the ancient maya city of Chichen Itza, realized in occasion of the Maya display held at Palazzo Grassi in Venice (1998-99), represents a new chapter of the Palazzo Grassi official web site. This work is part of a research aimed at experimenting tools for three-d scene navigation, in order to improve the usability of simulation for desktop vr applications. This is a significant issue for multimedia systems integrated in cultural displays or multimedia titles using three-d visualization for large masses of users. The most part of three-d worlds representations conceived for personal computers offer panoramic pre-defined views or fragment large worlds into various scenes. The Chichen Itza project attempts to find an alternative solution, realizing a single fully navigable simulation: the goal is to give the user a comprehensive view of the city and, at the same time, to let him to examine the relationships between the single parts of Chichen Itza from any possible point of view; besides, an alternative interface has been implemented to allow the examination of the single monumental buildings. A lot of work has been devoted to the optimization and modularization of vector models both to achieve a decent frame rate on average computers and to have acceptable download times from the network. The concept of locus, introduced in a previous work as an attempt to give a better structure to virtual scenes, has been enforced and utilized here to help the user to orient itself through the city.
