	Compute the surface tangent patches over the whole surface in the angle interval from the cutting edge center to the top edge center.
AGXTERRAIN_EXPORT ShovelPlane	agxTerrain::computeShovelBottomPlane (agxTerrain::Shovel *shovel, bool debugRender=false)
	Compute the dominant cutting bottom plane using the backside surface structure.
AGXTERRAIN_EXPORT ShovelPlane	agxTerrain::computeShovelInsidePlane (agxTerrain::Shovel *shovel, bool debugRender=false)
	Compute the dominant inside plane using the inside surface structure.
