Hi,
Currently, you can run optimizer with INDEX_MESH | VERTEX_PRETRANSFORM | VERTEX_POSTTRANSFORM (you can do this with osgconv and OSG_OPTIMIZER env) afterwards to make indexed triangles list from it.
With tristripping being optional it'll be easier though

Hi,So I guess we should make it optional to build tristrip or not. It's completely insane the performance difference I have.Cedric Pinson

To fix this I disabled the stripifier in my osgconv bin when using simplifier.I was curious if it makes sense for some other usage ? in the osgjs I use it but at the end I generate dummy vertexes to make one big strip without that it just drains performance.I mean if everybody feels the same we could start to submit patch to avoid it or as a standalone operation.Any other thoughts about it ?Cedric Pinson
