[vtkusers] Drawing circles?

[Saigopal Nelaturi]

Hi..
I'd like to know how to draw circles within the render window with floating point center and radius. vtkImageCanvasSource2D has a DrawCircle method but this takes in only integer values of the center. On the same subject, is there any function in vtk that will allow sampling of uniformly distributed points on a circle or a line ... ?

Thanks in advance,
Sai
