Abstract: | In this work we propose a new approach for fast visualization and exploration of virtual worlds based on the use of cartographic
concepts and techniques. Versions of cartographic maps with different levels of details can be created by using a set of operations
named cartographic generalization. Cartographic generalization employs twelve operators and domain-specific knowledge, being the contribution of this work their
transposition to 3D virtual worlds. The architecture of a system for 3D generalization is proposed and the system is implemented.
Differently from traditional cartographic processes, we use artificial intelligence for both selecting the key objects and
applying the operators. As a case study, we present the simplification of the historical quarter of Recife (Brazil). |
