Different projection matrix per viewpoint

[dcnieho]

Sorry to keep adding. to the last message:
specifically, i am trying to get the following info:

w,h = viz.MainWindow.getSize()
params.resolution = (w,h)
params.refreshRate= viz.getOption('viz.monitor.refresh_rate',type=int)
params.FOVy    = viz.MainWindow.getVerticalFOV()
params.aspectr = viz.MainWindow.getAspectRatio()
print (params.resolution,params.refreshRate,params.FOVy,params.aspectr)

What i get is:
((3840, 1080), 60, 40.0, 1.7777777777777775)

which is not the Vive, but my desktop. How to get each of these from the Vive?

This is what i get after calling vizconnect.go(), with the vive setup file as argument (which works fine, 3D world looks good)
