tub [size] [las] [col] [dra] [sav] [vesc] [nsi] [map] |
Description
Polygon display in tube mode.
...
Will save the graphics of the tube as a dataset.
vesc [factor]
Vary size by scalars. Will draw the tube according to the scalar values. Used in 3D log display.
To set up a size directly in meters use a negative value; i.e. tub -200 vesc $vfac -- will display the tube with a max size of approximately 200 meters.
vfac is calculated like this:
set hmm [gvar doublebr 489] ; # get millimeter i x direction
set kmm 200 ; # the tube size in this example
set vfac [expr $kmm / $hmm] ; # the scalar factor in this example
las
Draw the last line back to first point in the cell.
...
Tube the cells with color shift (at random).
nsi [number_of_sides]
Specify number_of_sides in the tube.
map
Map the scalars of the tube data.
Examples
