Abstract: We compare computational results for three procedures for reconstruction and texturing of 3D urban terrain. One pro¬¬cedure is based on recently developed “L1 splines”, another on conventional splines and a third on “α-shapes”. Computational results generated from optical images of a model house and of the Gottesaue Palace in Karlsruhe, Germany are presented. These comparisons indicate that the L1-spline-based procedure pro¬duces textured reconstructions that are superior to those produced by the conventional-spline-based pro¬ce¬dure and the α-shapes-based procedure.
