Re: [Jsbsim-devel] new ground-reaction with real terrain

[grtuxhangar t. <grt...@gm...>]

Sinking animation: the trick is to define contact point  retractable  and
to define a process  with a timer which start when in/on the water; it
retract sequentially  each contact point .
for instance within Blackbird the file
Aircraft/SR71-BlackBird/Systems/sinking.xml
