Hi Delport,
I have created a new class inherating the osg::Drawable::UpdateCallback. The
class structure is as follows:
*****************************************************************************'
class BlurCallback : public osg::Drawable::UpdateCallback
{
public:
BlurCallback(BlurPass *bp)
:_bp(bp),
_blurImage(false)
{
}
virtual void update(osg::NodeVisitor *nv, osg::Drawable *drawable)
{
osg::Geometry *geo = dynamic_cast<osg::Geometry*>(drawable);
osg::StateSet *state = geo->getOrCreateStateSet();
state->setTextureAttributeAndModes(0,
_bp->getOutputTexture().get(),osg::StateAttribute::ON);
}
BlurPass *_bp;
mutable bool _blurImage;
};
******************************************************************************'
.............................................
...........................................
polyGeom->setUpdateCallback(bpCallback);
The program crashes when it reaches the viewer.run(); If the comment the above
code
the application runs. I think i need to implement some kind of callbacks
implement what you have suggested in the last post. Isnt it?
Regards
Sajjadul
