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.
