Thanks a lot for your algorithms.

There was a bug in the export 3DMF function of my application, so 
there were more submitting of the same models.

I tried to add all the other optimization functions, but I didn't get 
your results.


I added the following code to the Geom test example, after importing a model:

	RemoveExtraReferences(notOptimizedModel);
	DecomposeGeometries( notOptimizedModel,theView );
	LowerAttributesToGeometries( notOptimizedModel);
	theModel=(TQ3GroupObject) FlattenHierarchy(notOptimizedModel,0 );
	OptimizeTriMeshes(theModel);
	MergeTriMeshes( theModel);


Working on the same 3dmf file that I sent you I have the following 
results (on an iMac Intel 2 core Duo)

Without optimization               18 FPS
With extra references removed     155 FPS
With all the algorithms           178 FPS

Maybe didn't I apply the algorithms correctly?

Thank you again,

Sauro Agostini
