vtkConvexPointSet::EvaluatePosition does not correctly set the interpolation weights
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When 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.
