"The viz3d API allows us to make a cv::viz::Camera with desired intrinsic parameters, and to use the camera by calling setCamera. These values appear to only "stick" the first time setCamera() is called."

Was this issue recently solved?

Can you run this code ? I must add :

Ptr<viz::Viz3d> myWindow = makePtr<viz::Viz3d>("setCamera() TEST");
myWindow->spinOnce(1);

to run it

Now I don't understand line 467 : 

transform->SetMatrix(vtkmatrix(proj_mat * old_proj_mat.inv()));

Shouldn't it be only :

transform->SetMatrix(vtkmatrix(proj_mat));

It is like setCamera is not having any effect...
