NAME

6       plw3d - Set up window for 3-d plotting
7

SYNOPSIS

9       plw3d(basex,  basey,  height,  xmin, xmax, ymin, ymax, zmin, zmax, alt,
10       az)

DESCRIPTION

13       Sets up a window for a three-dimensional surface plot within  the  cur‐
14       rently  defined two-dimensional window.  The enclosing box for the sur‐
15       face plot defined by xmin, xmax, ymin, ymax, zmin  and  zmax  in  user-
16       coordinate space is mapped into a box of world coordinate size basex by
17       basey by height so that xmin maps to -basex/2, xmax  maps  to  basex/2,
18       ymin  maps  to  -basey/2, ymax maps to basey/2, zmin maps to 0 and zmax
19       maps to height.  The resulting world-coordinate box is then  viewed  by
20       an  observer  at  altitude  alt  and  azimuth az.  This routine must be
21       called before plbox3(3plplot) or plot3d(3plplot).  For a more  complete
22       description of three-dimensional plotting see the PLplot documentation.

ARGUMENTS

30       basex (PLFLT, input)
31              The x coordinate size of the world-coordinate box.
32
33       basey (PLFLT, input)
34              The y coordinate size of the world-coordinate box.
35
36       height (PLFLT, input)
37              The z coordinate size of the world-coordinate box.
38
39       xmin (PLFLT, input)
40              The minimum user x coordinate value.
41
42       xmax (PLFLT, input)
43              The maximum user x coordinate value.
44
45       ymin (PLFLT, input)
46              The minimum user y coordinate value.
47
48       ymax (PLFLT, input)
49              The maximum user y coordinate value.
50
51       zmin (PLFLT, input)
52              The minimum user z coordinate value.
53
54       zmax (PLFLT, input)
55              The maximum user z coordinate value.
56
57       alt (PLFLT, input)
58              The viewing altitude in degrees above the xy plane.
59
60       az (PLFLT, input)
61              The viewing azimuth in degrees.   When  az=0,  the  observer  is
62              looking  face  onto  the  zx  plane, and as az is increased, the
63              observer moves clockwise around the box when viewed  from  above
64              the xy plane.
