Detailed Description

create oriented ribbons from lines defined in polygonal dataset

Date
2003/01/09 19:21:05
Revision
1.43

vtkRibbonFilter is a filter to create oriented ribbons from lines defined in polygonal dataset. The orientation of the ribbon is along the line segments and perpendicular to "projected" line normals. Projected line normals are the original line normals projected to be perpendicular to the local line segment. An offset angle can be specified to rotate the ribbon with respect to the normal.

Warning:
The input line must not have duplicate points, or normals at points that are parallel to the incoming/outgoing line segments. (Duplicate points can be removed with vtkCleanPolyData.) If a line does not meet this criteria, then that line is not tubed.
