Either you're mesh-modelling-programm exported them,
or you have to calculate them yourself, if you have
access to the data. If you've only got the mesh, Warp
has written a mesh-smooth-programm (for DOS and
Windows with DOS-Support) which will take a scene,
and add the normals for mesh-objects. Here's the link:
