NAME
dome - geodesic dome design
SYNOPSIS
dome [-fnnn] [-cn] [-px] [-s or -sb] [-en] [-v] [-dn] [-rn] [-w] [-h]
[filename.xxx]
DESCRIPTION
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.
OPTIONS
-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.
EXAMPLES
- 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
