[vtkusers] How to transform discrete points to continuous field

[Joker Lee]

Hi there.
I am new to vtk.
I have a project that need to use vtk to show a 3D temperature field. The
original data are tempretures of some discrete point. I use interpolation to
increase the density of points, but how could I use these discrete points to
create a continuous field?

Thanks in advance.
