Have you tried with the CVS (5.1.0) version of VTK?

Hi, all

 

I have posted this on paraview newslist, but I think it may be vtk problem.


 

-----------------------------------

I have  built a polarized passive stereo display system based on one
computer equiped with two projectors. It works well in side-by-side mode
stereo. Recently I installed paraview as one application on it with some
modificaiton made paraview to support side-by-side stereo. The modification
is very simple : just split the viewport into two parts and show the
left-eye image and right-eye image side-by-side. Although it works, its
stereo effect is not good, especial when scaling objects. I wish an effect
like flying over the objects, so is it necessary to set the stereo
parameters on flying?

 

I read the codes calculating stereo pair in paraview.  Its major part is in
the function 

 

void vtkPerspectiveTransform::Shear(double dxdz, double dydz, double zplane)

 

I think this is a toe-in stereo pair generating model, which is not quite
good, is it so?
