Summary0009453: vtkConvexPointSet::EvaluatePosition does not correctly set the interpolation weights
DescriptionWhen plotting over a line that encounters vtkConvexPointSet cells, the Plot Over Line filter gives incorrect results. This is caused by incorrect weights being set by vtkConvexPointSet::EvaluatePosition, where the weights relative to all sub-tetrahedra are set, instead of just the closest one. This results in a set of weights that can not give correct interpolation results in filters like Plot Over Line.

A patch to fix this is attached.

This needs to get into the 3.6.2 version, unless the patch doesn't work and this bug ends up not being easy to fix.

The patch was verified and was applied to vtkConvexPointSet.cxx. Note that this bug is related to bug 0009550. In addition, a bug with EvaluateLocation() was fixed.

Thanks go to Bart Janssens.

Need to get rid of a print statement - it says "Executing with:" ...

My bad. My comment was placed on the wrong bug.

I don't really know how to test this, so since Bart wrote the patch, and Zhanping applied the patch (I assume looked at it), I am marking it fixed. If this isn't the case, please re-open it.
