[vtkusers] VTK rendering 2D mesh

[kenichiro yoshimi]

Hello mafiaskafia,

You can render the wireframe edges of the mesh and set color of them
in the following way.
---
    colors = vtk.vtkNamedColors()

    #Create an actor
    MeshActor = vtk.vtkActor()
    MeshActor.SetMapper(MeshMapper)
    MeshActor.GetProperty().EdgeVisibilityOn()
    MeshActor.GetProperty().SetEdgeColor(colors.GetColor3d("White"))
---

Best
