pol_recip - polar reciprocals (duals)
pol_recip [options] [input_file]
Read a file in OFF format and make a polar reciprocal from the face planes.
- input_file
- input file in OFF format, or if not given the program reads from stdin
- -h
- program help
- -c <cent>
- centre of reciprocal sphere, in form "x_val,y_val,z_val" (default: "0,0,0")
- -r <rad>
- radius of reciprocal sphere (default: 1)
- -R <verts>
- radius of reciprocal sphere using centroid of vertices given by index
(starting from 0) in form "v1,v2,v3,...", radius is distance from
centre to centroid of "v1, v2, v3..."
- -o <file>
- write output to file, if this option is not used
the program writes to standard output
Make a cube whose vertices are the mid-points of an octahedron's faces
pol_recip -o cube.off -R 0 octahedron.off
A dual of a convex polyhedron is normally made with the centre of
reciprocation at the polyhedron centre and the radius to reach the
edges mid-points.
