GenerateMesh macro command

Print this Topic Previous pageReturn to chapter overviewNext page

Macro commands may be used either in macros or by sending the commands to DPlot via dynamic data exchange (DDE). Some commands are valid only in macros (noted by Macros Only). Commands sent to DPlot via DDE must be enclosed by square brackets [     ]. Macro commands should not include the brackets.

Command parameters shown in the descriptions below are placeholders for the actual values. Command parameters are either numeric values, equations that evaluate to numbers, or character strings. Character string parameters are always bound by double quotation marks. Equations must be preceded by an equals sign (=).

The pipe symbol (|) in the command syntax indicates that a parameter is optional, and should not be included in your macro unless otherwise noted.

All indices into arrays are 1-based, e.g. Curve1=1 refers to the first curve in a plot.

A 0x prefix for numbers in the descriptions below indicates hexadecimal notation; e.g. 0x0010 = 16.

JR/Viewer indicates that the command is supported by DPlot Jr or DPlot Viewer.
JR/Viewer indicates that the command is NOT supported by DPlot Jr or DPlot Viewer.


 

[GenerateMesh(nx,ny,xll,yll,xur,yur,method,extrapolate,np)]

JR   Viewer

Generates a new document containing a rectangular grid of 3D points from the currently active 3D surface plot. For more information see the description of the Generate Mesh menu command.

nx, ny

Number of grid cells in the x and y directions.

xll, yll

Coordinates of the lower left corner of the generated grid.

xur, yur

Coordinates of the upper right corner of the generated grid.

method

=1 to use planar interpolation, 2 to use quadratic interpolation. 0, which in former versions used a (sometimes unstable) bivariate interpolation, will be replaced with 2 automatically.

extrapolate

If non-zero, will generate z values outside the existing triangular mesh (if necessary). This option has no effect if method=1.

np

Number of control points to use for quadratic interpolation. This value should be 3 or greater; 4 works well for generally smooth surfaces. Ignored if method=1.
