This program generates a file containing a header with x and y sizes,
followed by the data in 8-bit greyscale, one pixel to a character, in
scanlines. There are two necessary input files: ball data, and a
pattern bitmap. The tiling bitmap can be digitized data, it must be in
the form of scan lines no longer than 512 bytes followed by newlines.
The ball data is of the following form:
x y z rad ior refract reflect diffuse ambient
on each line where x y & z are the coordinates of the center of the
ball, rad is the radius of the ball, ior is the index of refraction
for translucent materials (index of refraction for glass is about 1.5)
the last four numbers determine how much of each attribute is used.
Thus a pure silver ball would have 0.0 1.0 0.0 0.0 as the last
numbers,
and a pure glass ball would have 1.0 0.0 0.0 0.0 .
