Instancing of track symbols

Hi,

Is there any way of instancing track symbols/points using osg/osgEarth?

I have spotted the following in the code: InstanceResource, IconSymbol, InstanceSymbol.

But is not clear how I can use these.

Thanks
Damian

Damien,
Can you explain at a higher level what you are trying to do?

Re: Instancing of track symbols

Hi Glenn,

I am attempting to display 1000's of TrackNode's.

When I display 1000 TrackNode's with an image which is 16x16 I see performance drop from a solid 60fps with no TrackNode's to 30fps in release mode. As I add more tracks the fps drops further still.

The positions are being updated once per second.

The system I am running on has a GTX1050, i7-7700HQ, 16GB of memory.

Thanks
Damian
