Re: [osg-users] mouse/viewport issues with CompositeViewer

Hi Bob,

Yes moving to 2.5.3 or SVN will fix this issue.

 Look closely - the scene moves, just *very very* little.

 It's a bug in osgViewer/CompositeViewer.cpp which I submitted a fix for
 about a week ago. When a single view is on multiple displays (so the
 slave camera mechanism in osgViewer::View is used) the viewport extents
 are not set correctly in the eventTraversal, so when the mouse events
 are translated they have wrong values and the mouse movement has very
 little effect.

Hi Bob,


I am wondering about the status of this bug/fix (below) that I originally saw 
discussed back in late Feb. by Paul M., Jean-Sebastien and Robert, and again in 
late May, with no firm resolution.  I am using OSG 2.4 and appear to be 
experiencing this same problem using CompositeViewer and slave cameras.  Is the 
only current option to drop down to osgViewer::Viewer, or will doing a current 
SVN checkout resolve it?


This fix was committed and is part of OSG 2.4. Perhaps you're seeing 
something different, or perhaps it's come back to haunt us? :-)


Try this:

osgpick --CompositeViewer

Does that exhibit the same symptoms as the ones you see? This was the 
test bed for the patch I submitted. If the patch was not applied, trying 
to rotate the fountain when the composite viewer was on two screens 
(hence using slave cameras) gave very little movement. For me at least, 
that example shows me that it's fixed.
