The problem is that through osg there is no way to get the raw mouse
values. In normal mouse mode you can get the x, y and the delta values
but once you move the mouse to the extent of the window we no longer get
deltas even though we move the mouse. The quick and dirty solution is
to recenter the mouse at 0,0 every time so that you can get the delta
values. If there was a way to access the raw mouse values so that even
though the extent of the window was hit and you would still get delta
updates then there would not be an issue. If you have any ideas of how
to build this type of motion model without having to warp the mouse
pointer I would like to hear about them.

Hi Brad,
Recentering the mouse on every frame or event seems like a real
overkill. I'd suggest you develop a manipulator that doesn't require
this.

Hi,
I am trying to make an FPS style motion model using OSG. Every frame I
calculate the mouse translation and then reset the mouse back to the center
of the screen. The problem is if I call
osgViewer::View::requestWarpPointer() to re-center the mouse I seem to flood
the system with input events and the end result is that I seem to get much
fewer mouse movement updates. I changed my code to only re-center the mouse
if the mouse moved, but even still I am only getting a mouse moved event
about every third frame with continuous mouse movement. This leads to a
very choppy feeling mouse any ideas? Until the upgrade to OSG 2.0 the motion
model worked fine, ever since it's seemed as though we are not re-centering
it properly. Is there a better way to re-center the mouse?
