[vtkusers] Arrow with 2 points

[Darlon]

Hi.

I have two points: p1=(x1,y1,z1) and p2=(x2,y2,z2), and need to create an
arrow from p1 to p2.

I know how to create the arrow using vtkArrowSource and move the arrow to
p1, but how can i do to make that p2 be the final point of the arrow?

I am using linux, with g++ and vtk 5.0.


thanks
