Hi Robert,
First, thanks for the answers.
Next, I get my camera stats, it contains a lot of things :
In _collectMap there are (gpu, true) and (rendering, true), and in
_attributeMapList there are 25 item, which are empty or containing some
things like "cull traversal begin time" or Draw traversal begin time".
After the call of stats->collectStats("scene",true); there are no more
information in the _attributeMapList ... In the code I see that it just add
one flag in the _collectMap so how can I get the scene informations ?
How, I just found that in the stats I wait for are set in the Renderer.cpp,
but in the osg 2.6.1 I didn't found them ... If i'm right ... I cannot get
these stats with the 2.6.1, isn't ?
Thanks.
Regards,
Vincent.
