[ODE] dCylinder problems and future

[Chroma]

AB> That would be fine, but it should be rotated so that it faces the same
AB> way as the capped cylinder.
Imho it's the capped cylinder that should have the same orientation as
the regular cylinder. The orientation of the cylinder looks more
standard to me. I may be wrong.. :)

AB> Also, a mass function for it would be nice.
That has already been implemented in the cvs (dMassSetCylinder)
