After reading D777 post, I recognized that I messed up TRANSONIC. Going
by real physics SUPERSONIC already includes TRANSONIC. Right. And
HYPERSONIC is quite to far away on the velocity scale for WipEout HD. xD

In mathematics we usually don't really use the engineering terms to classify
a flow regime because those don't incorporate important quantities that are
essential to all of aerodynamics. The single most important quantity is the
so-called Reynolds number.

Given that number it is possible to compute a fluid-flow simulation around
the ZONE craft based on the Navier-Stokes equations, the equations of
fluid motion. As a result, we would essentially see how the ZONE craft
sheds vortices and how the shock waves build up round the craft and how
they are reflected back and forth on the track. I tell you, that would be the
most stunning thing ever.

Here is an example of an aircraft flying at transonic / supersonic speed
with some visible shock waves;



However, doing such a simulation and visualization is very time consuming
and very complicated to set up and to compute, esp. if you wanna simulate
the flow at transonic / supersonic speed (very high Reynolds number flow).
You can compare it to an actual fluid-flow simulation around a jet-fighter.
Anyways, I can do it. I've studied it all and have done similar simulations
before. Would be a nice spare time project. I just simply need the
surface vertices of the ZONE craft. The only one condition is that these
vertices should be aligned in such a way that after triangulation a
mesh would result without any holes.

Have a break...
