Member Function Documentation
◆ Evaluate()
|
overridevirtual |
Curve evaluation.
Given a parameter "u", finds position on line of the kind p=p(u); note that u is in the range 0...1, to make a complete cycle along the cam
Implements chrono::geometry::ChLine.
◆ Get_weight()
|
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)
◆ GetClassType()
|
inlineoverridevirtual |
Get the class type as unique numerical ID.
Each inherited class must return an unique ID.
