Member Data Documentation

direction1

ignition::math::Vector3d direction1

Vector for specifying the primary friction direction, relative to the parent collision frame.

The component of this vector that is orthogonal to the surface normal will be set as the primary friction direction. If undefined, a vector constrained to be perpendicular to the contact normal in the global y-z plane is used.
