[vtk-developers] about stereo mode and parameters

[daniel]

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?
