[osg-users] Custom stats?
Hi, I'd like to display some custom stats every frame. For example, I have a custom drawable which I'd like to display some information about. What's the best way to go about doing this? Thanks, Brett ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Custom stats?
HI Brett, Just have a look how the present stats are done via the StatsHandler, it should tell you the various things that can be done to get things renderered and updated - there should be no need for custom drawables as it can all be done with standard OSG objects.

Re: [osg-users] Custom stats?
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

Re: [osg-users] Custom stats?
Hi Brett,
Thanks for the further explanation, I know understand a bit more about
what you are after. I'm afraid off the top of my head I can think of
the specifics of what you'll need to do. You may well need to write
you own traversal of the main view's RenderStage rather than relying
upon the RenderBin::getStats(..) method.
Robert.
