Nuages

This is Bernhard Geiger's (INRIA) reconstruction package. Input: a set of simple closed polygons on parallel planes. There may be several (nested) polygons per plane. Output: A set of triangles representing the surface of a 3D polyhedra, and/or a set of tetrahedra filling the 3D polyhedra. The program adds vertices onto and inside the contours. How to display the output: The program currently supports wavefront .obj format, DXF format and Object File Format (.off) format. The latter can be visualized with geomview on sgi and NeXT. Geomview is available at geom.umn.edu. Conversion tools to other file formats can be found at avalon.chinalake.navy.mil. How to get input data: The input format is a simple ascii file (see man prepros for a format description). Several contour sets can be found at betelgeuse.inria.fr /pub/Contours.
