Summary: Feature Flow Fields (FFF) are an approach to tracking features in
a time-dependent vector field v. The main idea is to introduce an appropriate
vector field f in space-time, such that a feature tracking in v corresponds
to a stream line integration in f. The original approach of feature tracking
using FFF requested that the complete vector field v is kept in main memory.
Especially for 3D vector fields this may be a serious restriction, since the
size of time-dependent vector fields can exceed the main memory of even
