[Paraview] Re: Rendering problem....

[Berk Geveci]

VTK actually uses double precision for this sort of stuff. However, a
lot of times the point coordinates come in as float. Also, there may
be some intermediate variables that we missed in the float -> double
conversion. Also, OpenGL uses float not double :-) It is a difficult
problem...
