Hi Generally in many cases yes IVE's will/can help improve your runtime performance especially load time, when converting from other formats such as 3DS, FLT to IVE optimizations can be done that can aid the run time as well , but could model a lot of that as but most folks don't model that way these days, it's a skill that being lost
Whatever the run-time you use it is generally found that the native binary format IVE in the case of OSG will typically outperform the generic modeling formats Having said that how you model a feature or set of features can also dramatically improve or hit the runtime performance whether or not you use IVE etc Gordon Tomlinson Product Manager 3d Technology & Project Wyvern Overwatch(r) An Operating Unit of Textron Systems -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Yong Wang Sent: Wednesday, April 14, 2010 10:39 AM To: OpenSceneGraph Users Subject: Re: [osg-users] 3D model fomat Hi, Gordon: Thanks a lot for your quick response, does that mean IVE provides better performance for runtime?

Others uses 3ds and obj fine but I' also old school and know Creator very well. (Main problem with Creator is simply cost compared to other tools ) We recently created a SKP importer/export for Sketch up to OSG and the models that come out of Sketch up are no really ready prime time Vis-Sim it create what to complex models that look very simple in SketchUp but when exported become nightmares...

What is the best 3D model format I should use? Is it OpenFlight, or 3ds, or obj?
