Description

This command returns the new parameterization of 2D points (u_coords, v_coords). The original parameterization (id_joints) is modified using the given chordal deviation (val_chordaldev). An empty string is returns if it isn’t possible to find a parameterization with the specified chordal deviation.

Look into hm_lineparameterization for the joints definitions.

Example

To re-parametrize (new_joints) 2D points (u_coords,v_coords) with a chordal deviation of 0.5 (val_chordaldev), it is necessary to define the list of u points coordinates and v points coordinates and the to define the original parameterization using joints list.

set id_joints [list 0 2 4 21 23 24 25]
set new_joints [hm_lineapplychordaldev $u_coords $v_coords $id_joints 0.5]
The final parameterization will be “0 2 4 9 13 21 23 24 25”.

Errors

if { [llength $new_joints]==0} { 
#Handle error here //I can't find the new parameterization.
