[vtkusers] vtkDelaunay3D filter generate a tetrahedral mesh

[Ali Habib]

Dear All,

I have two questions regards tetrahedral mesh generated by vtkDelaunay3D

1. how to display the output, it give me always error regard scalar values
(even I added array of scalers) attached is the code it was written using c#
,

2. I want to get the matrix of Neighbors how can I do that please

best regards
