Abstract: Large terrain databases require a great number of polygons and textures. In consequence, transmission of terrain data over slow networks is still worrying. Multiresolution models allow progressive transmission, that is, the transmission of a simple model followed by successive refinements. In this work we describe a new multiresolution model called Geometric-Textured Bitree (GTB) that enables progressive transmission of both geometry and textures of a terrain model. Wavelet Multiresolution Analysis is applied in different steps of the process: selection of geometric points, texture classification and segmentation. An innovative texture synthesis process based on Wavelet classification is used in the reconstruction of the texture model.
