Spline Dynamics

HAIR contains complete spline dynamics functionality, including collision detection for objects with Collision tags. With just a few exceptions, splines will behave just as the guides of a Hair object. Simply apply a Spline Dynamics tag to a spline object (not to a spline primitive!).

In order to better understand how spline dynamics work, imagine springs attached to the spline points as pictures below:

The spline points represent the spline dynamic’s mass points connected by springs.

Tip:
The internal number of points on splines that have hair and are animated (whether via PLA or spline dynamics) tends to change, which can lead to hair-raising results. You can avoid this by selecting None in the spline’s Intermediate Points menu.

Example (cables)

Spline dynamics are perfect for creating cables. First, create a linear Spline (in our example, MoGraph’s Tracer Object was used). The spline end points (connection points) were given a Mass of 0. Play the animation - and voilá!
