◆ Get_weight()

double chrono::geometry::ChLineCam::Get_weight ( double par ) const

inline

Weight evaluation.

Given that the shape is defined by a Ch_function, the returned weight is the weight of the function (Ch_function_sequence can have different 'weight' values depending on the function segment)

The documentation for this class was generated from the following files:
