[vtkusers] the adjacent question, again

[PAUL]

Hello all:

I have been baffled the question for a long time. 

I am studying an algorithm of judging convex or non-convex polyhedron.

 

I have a question to ask:

When an arbitrary vertex is accessed, how to know the other three vertexes'
coordinate?

For an example, there are eight vertexes on a cube. And each vertex is
adjacent to the other three vertexes, just as the vertex A is adjacent to
the vertex B, C, and D.

If the vertex A is accessed, how to know the coordinates of B, C and D?

 



I need your helps! Thank you!!
