Robert,
I already have a custom drawable; in fact that's what I want to view the
stats of. For example, in the drawable is some openGL code which
produces some billboards, and I want to know show how many billboards
it's drawing. When I toggle the stats on and off, I'd like to see
something like "Billboards: 2040" along with the framerate info etc.
I've looked at the stats handler and traced the code around. Here's what
it seems like I need to do... Please correct me if I'm wrong.
1. Add attributes to osg::Stats for the things I care about. (ie:
"Billboards")
2. Derive from osg::statsHandler to get at those attributes and draw them.
I'm a little confused here about the link between stats and statistics
but it seems like I also need to...
3. Derive from osg::Statistics (BillBoardStatistics) and add members for
things I care about ("ie: myNumBillboards").
4. Add an "accept" method to my custom drawable class so that when the
osg::statsvisitor visits I can get at my derived BillBoardStatistics
class and update it with info about the number of billboards.
Like I said, I'm confused about the connection between osg::stats and
osg::statistics. Is there a connection? How does it work?
Am I just way off here?
Thanks,
Brett
