Hello
I'm trying to make a GPU texture loading strategy based on an osg::Image.
I maintain update bounds in a derived MyImage class in a setData method and
would like to use glTexSubImage in order to update local Image changes so I
implement a coupled Subloadcallback in order to do that.
But I don't manage the Subload Method to be called as when I call dirty on
osg::Image it always call the Load Method.
Can you tell me what to do in order to make Subloadcallback::SubLoad to be
called?
MySubloadcallback : public Subloadcallback {
load(...){
cout<<load<<endl;
}
suloadoad(...){
cout<<subload<<endl; //never display
}
}
static MyImage img;
main(){
img.setSubloadCallBack(new mySubloadCallBack());
...
viewer.run();
}
