This function will sample coordinates along the splines and save the coordinates as a mod file. The mod file will be labeled with object_id=1 and contour_id=i+1, where i is the index of the spline.
Parameters:
Name | Type | Description | Default |
---|---|---|---|
save_path
|
Path
|
Saving path. |
required |
interval
|
float
|
Sampling interval along the splines. For example, if interval=10.0 and the length of a spline is 100.0, 11 points will be sampled. |
10.0
