[vtkusers] Quadratic triangle + linear edge - cell scalars incorrect (vtk 4.5)

[John Platt]

Hi Users,

 

When I add a linear edge to an unstructured grid consisting of a single
quadratic triangle, the centre linear triangle of the triangulated
quadratic triangle and the edge have swapped cell scalars - see
attachment (triangle should be all red & edge blue).

 

When either of the cells is drawn in isolation there is no problem.

 

The cell scalars coming out of
vtkDataSetSurfaceFilter::UnstructuredGridExecute() appear OK.

 

Does anybody else have this problem? I have attached the c++ code just
in case it is a fault on my part.

 

Many thanks for your help.

 

John.
