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.

27 This function is examples 8,11,18,21.
28
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.
