[vtkusers] VTK Pie in 3D

[Bhanu Hariharan]

Hello,

I am trying  to visualize some sort of 3D discs/donuts at certain X Y Z
locations in a grid - whose radii and color will depend on user selected
values - i.e each disc with a different radius and /or color.

I could think of doing this with VTKTubefilter where I can vary the radius
and color of each disc.
Is there a better way of doing this.

Further sometimes I need to split the disc/donut into 2 or 3 different
section and color using different colors sort of like a 3D Pie. Can this be
done in VTK.
Is there anything like vtkTubefilter that can do this?

Any help and ideas is very appreciated.

Thanks,
Bhanu
