Some notes:

The MakeCharacter () macro uses the following variables:

Coordinate [] is an array containing <x, y> spline coordinates plus a diameter
multiplier. The actual format is <x, y, multiplier>.

NPoints indicates the number of spline points in the Coordinate [] array.

HeightFactor adjusts the scale of the character without changing the diameter.

BaseRadius is the default sphere_sweep diameter.

UseLastMinsAndMaxs is useful for making multiple parts of a character to be
unioned together.

It's fairly easy but a little tedious to make characters with this macro. What
worked for me was to make a bitmap image of the characters with a paint program
then mark locations along a path following the center of the character strokes.
The <x, y> coordinates of the marks can then be typed into Coordinate [] array
entries and if necessary the diameter multipliers can be adjusted. With a little
practice one can achieve acceptable results. Don't forget that the first and
last locations aren't actually plotted since the macro uses the b_spline
sphere_sweep method.

Happy raytracing!

Kind regards,
Dave Blandston
