plw3d: Set up window for 3-d plotting

plw3d ( basex ,

  zmin ,
  zmax ,
  alt ,
  az );
 

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 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 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.
