Wireframe drawings with Perspective

These are the results of poly_w2, a simple drawing program
written for X11 in C that takes text data in the form of
vertices and edges and draws the result with perspective.

One can learn many interesting things by importing data
from other programs. Very soon I found it necessary to
try to place objects at various distances from the
viewer to try to make them fit into the required size.

The very first 3d shape to be rendered correctly

Something of an experiment, transfer of TTF to Wireframe
One can see the letter is made by 2 polygons

Back to 3d, this time the TTF letter is extruded
