3D Terrain Reconstruction Based on Contours
Zhiyi Zhang, Kouichi Konno, Yoshimasa Tokuyama · 2006
In 3D terrain reconstruction, the differences of shape and topology among contours in adjacent sections cause a difficulty as the tiling problem of branching terrain. In this paper, we present a brief and pure geometrical algorithm to reconstruct 3D terrain based on contours. The merit of our method is that the tiling rules guarantee arbitrary branching terrain can be divided into correct topology.
