[vtkusers] Sphere with reticle

[James Kyle]

Thank you for your reply,

Here's the idea, I have a plain sphere being rendered. The sphere  
will move on 6 DoF (got some input for that). What I need is some  
sort of visual indicator that the sphere has moved. I was thinking a  
simple black cross hairs on the sphere surface would do the trick.

I checked out the vtkBoxWidget, but it looks a bit overkill with  
emphasis on user manipulation and interaction.

I've attached a file to show the simplicity of what I'm trying to  
describe...cept the attachment is 2d image rather then 3D sphere.
