Hi Christian,
To profile the peformance bottleneck it would be best to press 's' a
couple more times to get the full frame rate stats so you can see
exactly which parts of rendering are the bottleneck - the frame rate
only tells that you frame rate is reducing it doesn't give any clues
to why.

My source inside Bullet development indicates that fully functional

Hi Christian,
Out of interest are you simulating a penny push machine?
I had the same idea for a hobby project a while back. It's a great idea,
although it might be tricky to get the physics working nicely.
Unfortunately my ponderings stop there as I never found the time to get
on it.

Yes. These sucked the life out of my wallet on my last trip to
Shanghai and Hangzhou. Playing with virtual currency would be cheaper.

You could take a look at the draw instanced support in OSG, good for drawing
lots of things.
BRDFs could be used to render a high fidelity coin on just a couple
triangles without the flat, wallpaper-like effect of a regular texture map.
The first edition orange book included a section on

I believe this instancing capability might require Geforce 8 class hardware.
I was thinking along the lines of how the osgforest sample replicates
thousands of trees from
the same billboard drawable.
Hi,
I would use osgparticle.
You can induce rotations displacement.

Here is a first youtube video of my progress so far.

This is based on the osgBullet sample code found on the OpenSceneGraph
Wiki on Support/Tutorials.
A few things to note:
