vtkSelectVisiblePoints incorrect with non-square windows
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Some of the point labels in the attached python script disappear when resizing the window such that its width is smaller than its height. The inverse is true if the camera uses the horizontal view angle.
Is it a display vs. viewport coordinate system issue? Point visibility is done in viewport coordinates using the Z-buffer data retireved from the window (which is in display coordiantes?)
