NAME¶
plw3d - Set up window for 3-d plotting
SYNOPSIS¶
plw3d(
basex,
basey,
height,
xmin,
xmax,
ymin,
ymax,
zmin,
zmax,
alt,
az)
DESCRIPTION¶
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,
zmin and
zmax in user-coordinate 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 world-coordinate box is then
viewed by an observer at altitude
alt and azimuth
az. This
routine must be called before
plbox3(3plplot) or
plot3d(3plplot). For a more complete description of three-dimensional
plotting see the PLplot documentation.
Redacted form:
plw3d(basex, basey, height, xmin, xmax, ymin, ymax, zmin,
zmax, alt, az)
This function is examples 8,11,18,21.
ARGUMENTS¶
- 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 az=0, the observer is looking
face onto the ZX plane, and as az is increased, the observer moves
clockwise around the box when viewed from above the XY plane.
