Summary0013139: plot over line fails for small geometry
DescriptionThe plot over line filter fails for very small geometry. An example is if a user is trying to visualize cells or atoms, with units of meters. (The earth, in units of light years would have the same problem.)

plot over line. (This works)
Select Wavelet. Transform filter. Scale X, Y and Z by 1e-10.

Have reproduced the problem. Initially it seemed that the problem was with vtkValidPointMask all becoming 0. I first thought that it was a precision issue so changed the MaskPoints from char to int in the probe filter. This did not fix it and so I disabled the Mask points entirely. But the problem still persists. Will have to investigate a little more in depth of the vtkProbeFilter.

Moving to todo.

It has nothing to do with mask point or precision thereof. vtkProbeFilter::ProbeEmptyPoints() pretty much ends up producing nothing since all calls to vtkPointSet::FindCell() fail at the tolerance provided (which ends up being VTK_DBL_EPSILON).

The following commit recently added support to set threshold to use for probing. We should expose that in ParaView to address this.

    Change vtkProbeFilter to expose the 'in' threshold
    The error threshold for when a point is considered 'in' a cell can now
    be either computed as it was (default) or manually set on the probe

vtkPointSet::FindCell fails because vtkHexahedron::EvaluatePosition finds a determinant smaller than 1.e-20 - the function checks against this hard-coded value. Setting the threshold instead of calculating it will not fix this.

This is tricky to fix in general. See [^]

We will look at all cell types which have similar problems.
Special processing (scaling the data into a range of values that can be handled) has to be done to process data with vastly different scales. Floating point numbers (or doubles) cannot handle that.
