# dome(1)

geodesic dome design

## NAME

dome - geodesic dome design

## SYNOPSIS

**dome** \[**-f***nnn*\] \[**-c***n*\] \[**-p***x*\] \[**-s** or **-sb**\] \[**-e***n*\] \[**-v**\] \[**-d***n*\] \[**-r***n*\] \[**-w**\] \[**-h**\] \[*filename.xxx*\]

## 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

- **-f***nnn*

  Set geodesic frequency to *nnn*. The default is 2.

- **-c***n*

  Set class type to *n* (1 or 2). The default is 1.

- **-p***x*

  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.

- **-e***n*

  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.

- **-d***n*

  Enable paraboloid and specify focus location.

- **-r***n*

  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
