Forgive me for asking so many questions recently.  
I want to traverse each vertex, and set the color value for each vertex, and the coordinates of this process I will use its normal, I have its normals are calculated by using vtkTriangleMeshPointNormals, excuse me how can I get a vertex arrays or found the same data structure to access the information I need?  
I was puzzled about this for a long time.
