[vtkusers] How to turn volume data into triangle data (Not triangle strip)

[Jeffrey Meng]

Dear VTK users,

Does anyone know how to turn volume data into triangle data (Not
triangle strip)?

I know I could use vtkTriangleFilter to get triangle strips, but I
really want to iterate throught the volume data as triangles, so that
I could render each single triangle separately, it's faster than using
point data for sure.

So I guess, maybe my question could be rephrased this way: How can I
make each vtkCell a single triangle?

Thanks a million,
Jeffrey
