Factor Model Movies

The Chemometrics Group at Food Technology - KVL - has a great interest in bringing so-called factor models "to the masses". One way of doing this is by simple visualization to assist in teaching. On this page you can find examples of such movies/animations*) made by Nils Lastein for KVL. Please be aware of the considerable size of these files!

Please feel free to use them as you like - but respect our copyright!

*) The animations are made using 3D Studio MAX 5 from discreet.
**) Unfortunately we can not guarantee anything. Making the right, compatible format/codex turned out the be almost as difficult as making the animations themselves! "Progress" in computer-land is a funny thing.
