fmo — Fast modelling

Syntax

fmo [inc] | [nx ny] [x | y] [ibo] [spl [ten]] [vdf] [sdi]

Description

Generate a fast grid model using interpolation between lines.

Input to fmo must be line oriented polydata. The boundary of the grid will start where a line is first met.

Arguments

No arguments, the grid will have the same number of rows and columns as the last grid that set the @nrow @ncol variables.

inc xinc yinc

Create grid model grid with increments xinc and yinc.

nx ny

Create a grid with nx times ny grid cells.

ibo

Include border. Makes an extra rim of defined grid cells along the border.

x

Grid only in x direction. Default is in both direction. Uses the intersection of x or y gridding.

y

Grid only in y direction.

spl [ten tension]

Will apply a spline as interpolating method. Applying ten with the tension parameter tension having values from 0 - 100, results in a tighter spline. Try low values to get moderate tension.

vdf

Make a grid node if value defined in at least one grid direction.

sdi

Use line with shortest distance to calculate the grid node values.

Info
titleInformation

lst i 117

  • Will list maximum number of grid nodes that can be generated with fmo. Present value for release 4 is 12.2M nodes and for release 5 it is 15.2M nodes

val i 117 max_number_of_grid_nodes

  • Will set the maximum number of grid nodes that can be generated with fmo.
