DESCRIPTION
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.
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.)
SUMMARY
void SetWidth(float)
Set the "half" width of the ribbon. If the width is allowed to vary, this is the minimum width.
void SetAngle(float)
Set the offset angle of the ribbon from the line normal.
void SetVaryWidth(int)
Turn on/off the variation of ribbon width with scalar value.
void SetWidthFactor(float)
Set the maximum ribbon width in terms of a multiple of the minimum width.
vtkRibbonFilter()
Construct ribbon so that width is 0.1, the width does not vary with scalar values, and the width factor is 2.0.
