Following a Curvy NURBS Path for Animation
This tutorial shows how you can define a path for a part to travel along for
animation using a NURBS curve. This is good for animating objects like cars, trains, aeroplanes etc. and for animating IK control points.
One of the interesting things about this kind of animation, is you can modify
your animation while the anim bar is playing.
The nurbs curve is specified by the NurbsTrack
node. The easist
way to add a NurbsTrack is to add a PosionInterpolator as shown in the tutorial:
Beeline to Animation
(when you drag
the position of a part in anim mode a PositionInterpolator is automatically added
to the Anim bar) and then convert the PositionInterpolator to a NurbsTrack by right clicking on the
node and selecting convert to NurbsTrack
Same as with a NurbsLathe, new control points can be inserted by holding down
the right control key while clicking on the line between 2 control points..
A control point can be deleted by clicking on the control point and pressing the
The selected control point can be made to start a new curve by right clicking on
the NurbsTrack node in the scene tree and selecting new curve segment
