dome − geodesic dome design
dome [−fnnn] [−cn] [−px] [−s or −sb] [−en] [−v] [−dn] [−rn] [−w] [−h] [filename.xxx]
DOME is a program which calculates the properties of a geodesic dome symmetry triangle. DOME calculates spherical vertex coordinates, symmetry triangle topological abundance, and chord factors. DOME supports class I (alternate) and class II (triacon) breakdowns for Icosahedron, Octahedron and Tetrahedron polyhedron types. DOME also supports "Buckyball" formations as well as elliptical geodesics & geodesic parabolic dishes.
−fnnn |
Set geodesic frequency to nnn. The default is 2. |
||
−cn |
Set class type to n (1 or 2). The default is 1. |
||
−px |
Set polyhedron type to x, where x is i for icosahedron (default), o for octahedron, or t for tetrahedron. |
||
−s |
Generate full sphere data (default: symmetry triangle). |
||
−sb |
Generate a buckyball. Must use class I with frequency equal to a multiple of three. |
||
−en |
Enable elliptical formation (default: n=1 for a circle). n is the elliptical eccentricity (n > 0.0 and n < 2.0). |
||
−v |
Verbose data display at run-time. |
||
−dn |
Enable paraboloid and specify focus location. |
||
−rn |
Set outer radius of paraboloid. |
||
−w |
Enable wire-frame VRML or DXF output (default: face data). |
||
−h |
Displays a help screen. |
filename.xxx is a standard DOS filename, where xxx is DXF, DAT, WRL, POV or PRN.
A 5 frequency, class I, icosahedron sphere in DXF format (note class I and icosa are the defaults):
dome -f5 myfile.dxf
A 3 frequency buckyball in POV format:
dome -f3 -sb myfile.pov
A 10 frequency, class II, octahedron symmetry triangle in DXF format:
dome -f10 -c2 -po myfile.dxf
