Hi Martin,
You can't reuse (osgGA::GUIEventAdapter::DRAG) case in handle() because the scroll event needs to be cleared.
That's how we do it, and I didn't see any problems... Our code is quite
close to:
case (osgGA::GUIEventAdapter::SCROLL):
case (osgGA::GUIEventAdapter::DRAG):
Hi Jason,
osgParticle::PrecipitationEffect is design to be effectively infinite,
no matter how far you move it should repeat endlessly. I've done lots
of testing on town sized models and it certainly works in this context
fine.
My guess is that your scaling of the scene has introduced issues tha
Art,
I'm glad you were able to get the fbo to work in osgPPU.
Now you appear to be at the point I'm at with my application where the
resultant texture is no longer HDR and appears to be clamped at 1.0.
This is not the case with the Nvidia SDK sample (hdr) and I've tried to figure
out what O

only possibility would be to have osgmovie use something like SDL to

Hi Martin,
On Windows at least with viewer/viewerQT if you don't call
flushMouseEventStack() the handle() gets called repeatedly.
I suppose because there isn't really an end event for a mouse scroll.
We're on Windows, and we have a Qt-based application running this (among
others)... But we d
