Sets up a window for a three-dimensional surface plot within the
currently defined two-dimensional window. The enclosing box for the
surface plot defined by
,
xmin,
xmax,
ymin,
ymax and
zmin in user-coordinate
space is mapped into a box of world coordinate size
zmax by
basex by
basey so that
height maps to
xmin-,
basex/2 maps to
xmax,
basex/2 maps to
ymin-,
basey/2 maps to
ymax,
basey/2 maps to
zmin0 and
maps to
zmax. The resulting
world-coordinate box is then viewed by an observer at altitude
height and azimuth
alt. This routine must be
called before az plbox3 or plot3d. For a more complete description
of three-dimensional plotting see the section called “Three Dimensional Surface Plots”.
basex
(PLFLT, input)
The x coordinate size of the world-coordinate box.
basey
(PLFLT, input)
The y coordinate size of the world-coordinate box.
height
(PLFLT, input)
The z coordinate size of the world-coordinate box.
xmin
(PLFLT, input)
The minimum user x coordinate value.
xmax
(PLFLT, input)
The maximum user x coordinate value.
ymin
(PLFLT, input)
The minimum user y coordinate value.
ymax
(PLFLT, input)
The maximum user y coordinate value.
zmin
(PLFLT, input)
The minimum user z coordinate value.
zmax
(PLFLT, input)
The maximum user z coordinate value.
alt
(PLFLT, input)
The viewing altitude in degrees above the XY plane.
az
(PLFLT, input)
The viewing azimuth in degrees. When
, the observer is
looking face onto the ZX plane, and as
az=0 is increased, the
observer moves clockwise around the box when viewed from above
the XY plane.
az
