[vtkusers] Double precision in VTK

[egk865 at yahoo.com]

Are there any plans to support double precision in VTK anytime soon?
It seems that much of VTK is optimized primarily for
single floating point precision with many filters hardcoded to output
data in single precision even when the input to them is in double
precision.

One possible reason I can see why vtk may have been written
primarily with single precision in mind is that most modern
graphics cards are optimized for single precision and internally
store the data in single precision. However, not all applications
need to write to the graphics card and the ability for VTK to work
well with double precision data would be very useful especially for
science and research applications where accuracy is important.

Thanks,
