Hi Nikolaus,
I don't have too many models to test with, but while the new
OpenFlight loader isn't as fast as the old one yet, its a matter of
10-20%, rather than 10-100x as slower, so there must be something in
the make up of certain .flt files that the new loader is not coping
with yet.
I would very much like to see the new loader equal or better than the
old .flt loader, so tracking down the weak points is crucial. Is
there any chance you can publish the problem .flt file, or perhaps
create one that reproduces the performance problems?
Thanks
Robert.

Hi all,
when I switched my application to the new OpenFlight loader, the
performance drops dramatically:
Loading: 9.1 sec -> 29.4 sec
Optimizing: 1.2 sec -> 41.9 sec
Cull: 0.5 msec -> 53.8 msec
Draw: 5.3 msec -> 101.9 msec
Optimizing:
optimzer.optimize(_sceneGroup.get(), Optimizer::DEFAULT_OPTIMIZATIONS |
Optimizer::MERGE_GEODES |
Optimizer::COPY_SHARED_NODES | Optimizer::TRISTRIP_GEOMETRY);
For the flt-Loader the merging of GeoSets has been enabled by commenting
the line:
//dontMerge = true;
Some statistics:
Flt OpenFlight
96 32528 Drawables
8756 39527 Primitives
Obviously the "Optimizer::MERGE_GEODES" cannot compensate the missing
merging of GeoSet within the loader itself.
Any idee why?
Regards
Nikolaus
