XY Path [-/-]

Image:F6_Icon_Modifier2.png

The XY Path type uses a separate spline for the position along the X axis, as it does for the position along the Y axis.

To animate a coordinate control using an XY path, right-click on the control and select Modify With>XY Path from the context menu.


At first glance, XY paths work like displacement paths. To describe the path, change frames and position the control where it should be on that frame, then change frames again and move the control to its new position. Fusion automatically interpolates between the points. The difference is that no keyframes are created on the onscreen path. Look in the spline editor to find the X and Y channel splines. Changes to the controls position will be keyframed on these splines. The advantage to the XY path is that it becomes very easy to work with motion along an individual axis.

Contents




Controls Tab


X Y Z values

These reflect the position of the animated control.


Center

The actual center of the path. This can be modified and animated as well to move the entire path around.


Size

The Size of the path. Again this allows for later modification of the animation.


Angle

The Angle of the path. Again this allows for later modification of the animation.


Heading Offset

If other controls like e.g. a mask's Angle is connected to the path's heading, this control allows for adding or aubtracting from the calculated angle.


Plot Path in View

Toggles if or if not the actual path is displayed in the views.




Switching Default Paths Change the Default Path type used when animating a coordinate control to XY path (if this is the preferred type of animation). Open the Global preferences and look under the default's tab for the drop-down list in the default animate section labelled Point With. Change this from the current value to XY Path. The next time Animate is selected from a coordinate control's context menu, an XY path will be used instead of a displacement path.



Tips for XY Path (edit)

Although the keys of XYpath doesn't have handles you can modify their tension and rotation interactively in the view with the regular polyline hotkeys.

To name a few useful one:

  • w modifies the tension (on multiple selections too)
  • s scales the keys (or the tension on an individual key)
  • t rotates the keys

And finally the Shape box works as well. --Ata 20:26, 7 July 2009 (EDT)
