[vtkusers] How to generate a plane from three arbitrary points

[Xiaopeng Yang]

So do you mean I need to generate a triangle from the three points first?
May I ask how to generate it?

Hi Xiaopeng,

Use vtkTriangle::ComputeNormal() to compute the plane normal.
Then use the first point as the Origin of the plane.
