Hi Robert,
My current code instances a new one each cull traverse. I wonder if that means
I get a sizeof(osgUtil::RenderBin) memory leak each cull-traverse?
Anyway, I am going to try to multi-buffer it.
I should be able to count the number of cull-traverse calls I get for each
update tranverse. That (I guess) should tell me automatically how many
instances of osgUtil::RenderBin that I would need. I will multiply it by two
for double buffering and then it should work like a dream.
Cheers,
Viggo
