PLW3D

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.
