[vtkusers] Picking and perspective

[Robert Mitchell]

Dear Users,

Currently, to pick cells in my vtk window, I must position the mouse
further away from the centre of the window than the desired element. I'm

sure others out there have experienced this, and I was wonderng if there

is any way of correcting it. Has it got something to do with the
perspective of the rendering for a realistic scene - does the cast ray
go straight into (normal to)  the screen or does it get cast from the
camera  centre?

thanks,

Rob
