Triang.exe was compiled with DJGPP, gcc2.95.2
using the Allegro game library (WIP 3.9.32).

Triangles is a free DOS program, distributed without warranties or
guarantees. It is a "manual tri-mesh contruction utility" for making 
a mesh (mess?) of virtual triangles mainly using the mouse, and saving 
the result in a small choice of different formats (RAW , POV , PCM, 
and Triangles's own TRI format). 

I made Triangles mainly for use with POV-Ray. Triangles's capabilities 
are limited. Triangles has an upper bound on the number of triangles
allowed (currently 50,000). Even given the narrow niche Triangles is 
meant to fill, it is still missing many valuable features and I can't 
say that development will continue beyond my personal needs.

Setting up
Create a directory for Triangles. Unzip the downloaded zip file into 
this directory. To use under Windows, double click on the Triang.exe 
icon in Windows Explorer (or File Manager, or whatever), or get a DOS 
prompt and run Triang.exe. To use under plain DOS (not shelled to DOS 
from Windows), it is necessary to have the file CWSDPMI.EXE installed 
somewhere in your 'PATH', or in the directory you are running Triangles 
from. You will need to have video supporting at least 640x480 pixels x 
256 colors. A 'default' start up video resolution can be set by creating
an ASCII text file named 'triangles.ini' and making the first line one
of:
        640x480
        800x600
        1024x768
        1200x1024
or
        1600x1200
