sphereplot

  

plot a 3-D surface in spherical coordinates

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

sphereplot(L, r1, r2, options)

Parameters

L

-

procedure or expression having two variables, or list of three such procedures or expressions

r1, r2

-

ranges of the form var=a..b

options

-

(optional) plot options; see plot3d/option

Description

• 

Important: The sphereplot command has been deprecated.  Use the superseding calling sequence plot3d(args, coords=spherical), which is equivalent to the plots[sphereplot](args) calling sequence.  For more information, see plot3d[coords].

• 

The sphereplot command creates a three-dimensional plot of a surface or parametric surface in spherical coordinates.  The individual functions can be in the form of either expressions or procedures.

• 

If L is not a list, then L represents radius given in terms of theta and phi. Otherwise, if L is a list, then the three components represent radius, theta, and phi, respectively.

• 

The remaining arguments are interpreted as options which are specified as equations of the form option = value. These options are the same as those found in plot3d. For example, the option grid=m,n specifies that the set of points representing the three-dimensional plot is evaluated over an m by n grid of points. For more information, see plot3d/option.

• 

The result of a call to sphereplot is a PLOT3D structure which can be rendered by the plotting device. You can assign a PLOT3D value to a variable, save it in a file, then read it back in for redisplay. For more information, see plot3d[structure].

Examples

Important: The sphereplot command has been deprecated.  Use the superseding calling sequence plot3d(args, coords=spherical), which is equivalent to the plots[sphereplot](args) calling sequence.
