plw3d
: Set up window for 3d plotting
Sets up a window for a threedimensional surface plot within the
currently defined twodimensional window. The enclosing box for the
surface plot defined by
xmin
,
xmax
,
ymin
,
ymax
,
zmin
and
zmax
in usercoordinate
space is mapped into a box of world coordinate size
basex
by
basey
by
height
so that
xmin
maps to
basex
/2,
xmax
maps to
basex
/2,
ymin
maps to
basey
/2,
ymax
maps to
basey
/2,
zmin
maps to
0 and
zmax
maps to
height
. The resulting
worldcoordinate box is then viewed by an observer at altitude
alt
and azimuth
az
. This routine must be
called before plbox3
or plot3d
. For a more complete description
of threedimensional plotting see the Section called Three Dimensional Surface Plots in Chapter 3.
