HI Lars, Tools like osgAnimation and osg::AnimationPath are usable for this type of work, but for really large datasets I would tend towards writing a custom data structure for storing and accessing your data as this way you can optimize for memory constraints as well as performance.
For instance if you time values are a constant spacing then just storing the start time, and time delta, for the overall structure, then a simple std::vector<Vec3d/f> for the position data. Robert.
