void chrono::ChFunctionPositionLine::SetSpaceFunction ( std::shared_ptr< ChFunction > funct )

inline

Set the function u=u(s) telling how the curvilinear parameter of the spline changes in s (e.g.

time). Note: by default, u=u(s) is a linear ramp, so evaluates the spline from begin at s=0 to end at s=1.
