BoundaryEdges
VTKExamples/CSharp/Meshes/BoundaryEdges
Description¶
This filter will extract the boundary edges of a mesh. The original mesh is shown with the feature edges shown in red.
A tutorial on how to setup a Windows Forms Application utilizing ActiViz.NET can be found here: Setup a Windows Forms Application to use ActiViz.NETNote: As long as ActiViz.NET is not build with VTK version 6.0 or higher you must define the preprocessor directive VTK_MAJOR_VERSION_5.
