yes ... i've updated ODE's contrib/dCylinder directory with your newer
code. thanks.

yes, it's not exact for a cylinder, especially one that has a short
length (i.e. almost a sphere). however many simulations will not care
about the difference (it looks almost the same either way). anyhow, if
you write dMassSetCylinder() it can be added to mass.cpp along with the
other mass functions.
