[vtkusers] Bezier Curve in VTK 6.2.0

[Huang Li]

Hi all,

I am try to draw a 3D bezier curve by specifying 4 control points in VTK
6.2.0.
( just like the demo here
http://blogs.sitepointstatic.com/examples/tech/canvas-curves/bezier-curve.html
)

But I can't find any data source class to generate a vtkPolyData by
specifying bezier control points. Is there a such class in VTK? The closest
ones I can find are vtkParametricSpline and vtkParametricFunctionSource,
but I still can't figure out how to draw a bezier curve using these class.

I would very much appreciate any guidance or advice.

Best,
