The parameters are:
From: the eye location in XYZ.
At: a position to be at the center of the image, in XYZ world
coordinates. A.k.a. "lookat".
Up: a vector defining which direction is up, as an XYZ vector.
Angle: in degrees, defined as from the center of top pixel row to
bottom pixel row and left column to right column.
Resolution: in pixels, in x and in y.
Note that no assumptions are made about normalizing the data (e.g. the
from-at distance does not have to be 1). Also, vectors are not
required to be perpendicular to each other.
For all databases some viewing parameters are always the same:
Yon is "at infinity."
Aspect ratio is 1.0.
A view entity must be defined before any objects are defined (this
requirement is so that NFF files can be used by hidden surface machines).

Fill color and shading parameters. Description:

Format:
f %g %g %g %g %g %g %g %g
RGB is in terms of 0.0 to 1.0.
Kd is the diffuse component, Ks the specular, Shine is the Phong cosine
power for highlights, T is transmittance (fraction of light passed per
unit). Usually, 0 <= Kd <= 1 and 0 <= Ks <= 1, though it is not required
that Kd + Ks == 1. Note that transmitting objects ( T > 0 ) are considered
to have two sides for algorithms that need these (normally objects have
one side).
The fill color is used to color the objects following it until a new color
is assigned.

Polygon. A polygon is defined by a set of vertices. With these databases,
a polygon is defined to have all points coplanar. A polygon has only
one side, with the order of the vertices being counterclockwise as you
face the polygon (right-handed coordinate system). The first two edges
must form a non-zero convex angle, so that the normal and side visibility
can be determined. Description:

elements such as datatype cache require addition freeing
and so won't work with this. We could add a "free func ptr" to
qhead and call it here - so each element type can free any other

fold[i][i] has no meaning.
For 3D case as here, there will be at most 2 non-zero, non-diagonal entries.
Diagonal entries are useless here.
Further more, when the 2 non-zero entries are in the same row, the virtual cartesian is
unfolded from the row_id dimension onto the other dimensions in physical cartesian.
when the 2 entries are in the same coloum, the virtual cartesian is actually
folded from the physical cartesian.
4. perform_fold( vir_coord[], phy_coord[], fold[3][3] )
does the folding following the schedule given by fold[3][3].

is transitive. i.e., one can do
