[vtkusers] 答复: How to create a polyhedron(vtkPolyData) from a series of points(Vertex)

[Chen, Lifan]

I've read the code. In this example, it requires user to define the faces of the polyhedron, however, what I want is to automatically create the polyhedron with the given points based on some kind of rules, for example, the closest points rule. I know there is a method in vtkSelectPolyData to finish the similar work, but the method in vtkSelectPolyData does not create a polydata itself.

I think that this might help:

Subject: [vtkusers] How to create a polyhedron(vtkPolyData) from a series of points(Vertex)

Hey all,

I am new in vtk and here is a simple issue. How could I create a polyhedron from a series of points which are the vertexs of the polyhedron. Of course, these points do not intersect. Does any one know any method in vtk to accomplish this?

Thanks,
Fantasy
