It may be helpful to take note of this from:Īllow pin-slot joint to follow a spline (not just a linear straight line).Īllowing a pin-slot joint to follow a spline is essential as currently there is no way to properly represent designs that use curved sliders which are A VERY COMMON MECHANISM. Also note that using a different value range like degrees doesn't make sense for this and even for closed loops since there are an infinite number of loop shapes that are NOT a circle, so that degrees does not apply, makes no sense, and is just confusing. IMPORTANT: Also note that more commonly what you mentioned would use a scalar for the parametric argument to determine position where Zero is the primary position and One is the final position so that if it is out of that range then it goes beyond those positions and if it is a closed loop then this would still apply cycling through that loop and also the value could be cycled in either direction keeping it within Zero to One creating the effect you mention which only requires minimal modifications to the already existing pin-slot joint for this functionality. This allows use of the already existing pin-slot joint to just follow a spline and only requires one less constraint for 3D splines as a path reference providing a more simple implementation, especially since everything else is already there, no new tools or joints are needed which helps keep complication and confusion down.
