Descripción: Transmission of large terrain databases across the Internet is still worrying. A large terrain database requires a big number of polygons and textures, and that represents a problem with current bandwidth and resource limitations. Multiresolution models permit progressive transmission, that is the transmission of a simple model followed by successive refinements. In this work we present a new multiresolution model called Geometric-Textured Bitree. In contrast with most of recent works, it makes possible the progressive transmission of not only geometry but also the texture of a terrain model. Wavelet Multiresolution Analysis is applied to the selection of geometry points and, texture segmentation. Also a new texture synthesis process based on Wavelet classification is presented.
