Member Function Documentation
◆ GetCoefficientFriction()
|
virtual |
Get the terrain coefficient of friction at the point below the specified location.
This coefficient of friction value may be used by certain tire models to modify the tire characteristics, but it will have no effect on the interaction of the terrain with other objects (including tire models that do not explicitly use it).
Reimplemented in chrono::vehicle::RigidTerrain, chrono::vehicle::SCMTerrain, chrono::vehicle::RandomSurfaceTerrain, chrono::vehicle::GranularTerrain, chrono::vehicle::CRGTerrain, chrono::vehicle::ObsModTerrain, chrono::vehicle::FEATerrain, chrono::vehicle::FlatTerrain, and chrono::vehicle::CRMTerrain.
◆ RegisterHeightFunctor()
|
inline |
Specify the functor object to provide the terrain height at given locations.
This is provided as a potential optimization mechanism (certain derived classes may choose to ignore it).
◆ RegisterNormalFunctor()
|
inline |
Specify the functor object to provide the terrain normal at given locations.
This is provided as a potential optimization mechanism (certain derived classes may choose to ignore it).
