Hi, Justin,
Thanks for the info. Yes, I think "OSG_THREADING" is used by the
newer osgViewer, which alternatively takes the option --SingleThreaded
or --CullDrawThreadPerContext, etc. to switching between threading modes.
On the other hand, the older Producer based osgProducerViewer does use
"OSG_CAMERA_THREADING" to determine threading mode.
Regards,
Yefei
