Summary

0002911: vtkPoints precision

Description

I've been noticing point coordinates are sometimes off by 1/8 of a foot or so. I looked in vtkPoints.cxx and noticed that the default data type is still "float".

I was under the impression that since 4.2, the vtk point representation was changed to double (since PolyData functions like GetBounds and GetPoint return double values)

It was pretty easy to change this in the vtkPoints constructor. I just wanted to bring this up and suggest that either that double should be the default representation or that the class documentation for vtkPoints and vtkPolyData should make it clear that the points only store single precision floats.
