◆ CreateContactMaterials()

virtual void chrono::vehicle::ChTrackShoeSegmented::CreateContactMaterials ( ChContactMethod  contact_method)
protectedpure virtual

Create the contact materials for the shoe, consistent with the specified contact method.

A derived class must set m_shoe_sprk_material (used for contact with the sprocket) and m_shoe_materials which must include one or more contact materials for the collision shapes of the shoe itself (for contact with the wheels, idler, and ground).
