XSURFACE

The XSURFACE procedure provides a graphical interface to the SURFACE and SHADE_SURF commands. Different controls are provided to change the viewing angle and other plot parameters. The command used to generate the resulting surface plot is shown in a text window. Note that this procedure does not accept SURFACE or SHADE_SURF keywords.

This routine is written in the IDL language. Its source code can be found in the file


xsurface.pro

in the

lib

subdirectory of the IDL distribution.

Arguments

Data

The two-dimensional array to display as a wire-mesh or shaded surface.

Keywords

BLOCK

Set this keyword to have XMANAGER block when this application is registered. By default, BLOCK is set equal to zero, providing access to the command line if active command line processing is available. Note that setting BLOCK=1 will cause all widget applications to block, not just this application. For more information, see the documentation for the NO_BLOCK keyword to XMANAGER .

GROUP

Set this keyword to the widget ID of the widget that calls XSURFACE. When GROUP is specified, the death of the calling widget results in the death of XSURFACE.

Example

z = DIST(30) ; Make a 2D array.

XSURFACE, z ; Call XSURFACE. The XSURFACE widget appears.
