<div>Hi everyone,</div>
<div> </div>
<div>I would like to know how can I use vtk to cast a ray from a given point in a given direction and pick the intersection point of the ray with an actor. Basically I have 2 actors, one for rendering a poly data that forms an "outer shell" and another for rendering a poly data that forms an "inner shell". For every point of the inner shell, using it's normal, I would like to figure out where is the intersection on the outer shell, and I thought I could use ray casting method.

<div>If you have any ideas, please respond.</div>
