About Blender software
Blender is the free and open source 3D creation suite. It supports the
entirety of the 3D pipeline—modeling, rigging, animation, simulation,
rendering, compositing and motion tracking, even video editing and
game creation.

Blender - Object Data / Path
Animation
The Path Animation settings can be used to determine how child objects move along a certain path.
●Frames. The number of frames that are needed to traverse the path, defining the maximum value
for the Evaluation Time setting.
●Evaluation Time. Parametric position along the length of the curve that object following it should be
at (the position is evaluated by dividing by the Path Length value). By default, it is linked to the global
frame number, but could be keyframed to give more control over the path animation.
●Follow. Make the curve path children rotate along the curvature of the path.

Blender - Object Data / Path
Animation - Active Spline
The Active Spline panel becomes available during Edit Mode.
●Cyclic. Closes the curve.
●Resolution. Alters the smoothness of each segment by changing the number of subdivisions.
●Interpolation
●Tilt. Alters how the tilt of a segment is calculated.
●Radius. Alters how the radius of a beveled curve is calculated. The effects are easier to see after
Shrinking/Fattening a control point Alt-S.
●Smooth. Smooths the normals of the curve.
