i’ m on new demo with away3d physics
i try to improve memory on change of scene
all is delete except view and world.

(ex: for directional light with shadow i have to apply
MYLIGHT.shadowMapper.dispose(); or agal crach after 3 time )

if someone have best idea and time for that, you can look code.
on my website : CHAMASLOT at PHYSICS LABS

i also try to keep the script as simple as possible
i make the same for jiglib in next
(safarie give some error with javascript i have to fixe that)
