I have a floating point array p
representing a 3 dimensional stack
of shaped bricks projected onto
(possibly warped) film. Each brick
has 6 faces. I wish to use a
polyline of 8 points to display
each face. The faces of a brick
should be the same color.
$p
2 3 5 6 8 2
Rank 1 items are x y film coordinates.
A rank 2 item forms a polyline.
Rank 3 items are monochrome.
Color isn't particularly important, as
long as it differs from the background.
If color varies, best if it changes in
the 3 dimensional frame.
What please is a suitable way to display this?
