[away3d] As3dmod bend() constructor parameters?

[NickBee]

Can someone explain what the As3dmod bend constructor parameters
represent?
The documentation is a little limited as this point:


Bend() constructor

public function Bend(f:Number = 0, o:Number = .5, a:Number =
0)Parameters

f:Number (default = 0)
o:Number (default = .5)
a:Number (default = 0)

THANKS!!!!
