[vtkusers] 3d scattered points to 3d grid

[Ajit Rajwade]

Hello,

I have an array of irregularly spaced 3D points. The X,Y,Z coordinates of 
each point is known. Associated with each point is a certain data item D. 
Thus D can be treated as a function of X,Y,Z. I want to convert these points 
into a 3D grid with discretized x,y,z values. Is there any way to do this in 
VTK? Code snippets would be highly appreciated.

Thanks,
==ajit
