[vtkusers] Volume visualization of image slices

[Vidya Setlur]

Hi,
 
I'm new to VTK so pardon my question if it sounds simple. Basically, I have 5 images with a ball moving from left to right in these successive images. I have the 2D coordinates of the ball in each of the images. I need to be able to visualize the ball in 3D space (x, y, t) where t = total no. of images (which is 5 in this case).
 
Could someone please send me a pointer on how to do this? I would really appreciate your help, since it is rather urgent.
 
Thanks!
 
Vidya
