If you place spheres on a bezier-spline (just an example),
they will clutter up on beginnings and ending of a section.
Each section is defined by the already mentioned 2 Nodes
and their 2 directions. When using tiny T amounts, the
calculated positions may be very close to each other,
resulting in no centrifugal force.
It's like looking at a millimeter of a 100 meter curve...

In general, a section has some sort of curvature, and I would
like to use some general sort of the centrifugal force.

Its not very easy to explain...
