Geodesic Dome Design
                            DOME
                         Version 2.18

=============
What is DOME?
=============
DOME is a program which calculates the properties of a
geodesic dome symmetry triangle. DOME calculates spherical
vertex coordiantes, symmetry triangle topological abundance,
and chord factors. DOME currently supports only class I
(alternate) breakdowns.

=============
Why DOME?
=============
DOME began as a set of geodesic math test algorithims for
use in investigating properties of generalized geodesic
structures. This continues to be the main purpose of my
development of the DOME code. DOME should serve as a basic
tool for those interested in geodesic dome design and
modeling. All source code is also included in this package
and is freely modifiable under the conditions of the GNU
General Public License.

================
System Requirements
================
DOME has been complied using Borland C++ 3.1 to run on any
PC class system. Dome frequency is limited by the amount of
memory available.

================
Usage
================
Type DOME at the system prompt. The program prompts for the
polygon type, class type (only class I is supported in this
version) frequency of subdivision and file type. The program will
terminate with an error message if there is not enough
memory to allocate array space for the coordiante matrix. If
this occurs, re-run DOME and request a smaller subdivision
frequency. Only even frequencies are allowed when using class II.

DOME now supports command line inputs.
Usage: dome -fnnn -cn -i -o -t [-v] [-h] [filename.xxx]
Where: -fnnn is geodesic frequency (default nnn=2)
       -cn is class type (n=1 or 2) (default n=1)
       -i sets Icosahedron (default)
       -o sets Octahedron
       -t sets Tetrahedron
       -v disable data display at run-time
       -h displays a help screen
        filename.xxx is a standard DOS filename
        xxx = DXF, DAT, POV or PRN
================
File Formats
================
DOME currently supports four file formats:
	1.) DXF - DXF chord data which can be input into most
	          computer aided design packages.
	2.) DAT - An ASCII report format. Shows key dome parameters
	3.)	PRN - An ASCII comma delimited format. Contains vertex
	          coordinate and chord coordinate data. Suitable for
	          parsing into custom routines and spreadsheets
	4.)	POV - POV-ray script file. Generates spheres for vertexia
	          and cylinders for chords.

================
Other Goodies
================
A DXF to POV converter DXFTOPOV is now included. This utility facilitates
POV rendering generation of modified DXF data. This is handy if you use
a CAD program to rotate the symmetry triangle into a complete sphere.

Several sample GIF files rendered with POV-ray are included for fun.

================
DOME Updates
================
The next release of DOME should include:
Class II (triacon) breakdown systems
Rotation functions
Full sphere constructions
If all goes well It will be ready for release in the Spring
1995

Following releases will add:
Class II Method 3 Coordinates
Axial, dihedral, & face angle calculations
Truncation options
Space frame support
Non-spherical geodesic structure design
Graphical output
