Interpolation
Default Interpolation
The default type of interpolation Default Interpolation for new waypoints is defined by a dropdown list at bottom of the Canvas Window.
It is possible to fix interpolation by parameter. Right-click any and choose its default interpolation from a submenu. The defined interpolation is indicated in the Parameters Panel with corresponding icon near the parameter value.
Interpolation In & Out
Each Waypoint has an In
and an Out
interpolation setting, which determines the manner in which its parameter changes - whether it changes linearly over time, or follows a curve.
The In
interpolation defines how the parameter changes in the moments before the Waypoint is reached, and Out
defines how it changes in the moments after the Waypoint. Available interpolation types are as follows:
TCB: If you imagine a graph of the parameter’s value against time, using the TCB interpolation type will fit a smooth curve between adjacent waypoints, much like the |Spline_Tool| fits smooth curves between adjacent spline vertices.
Clamped: Acts like TCB interpolation, but never “overshoots” (or “undershoots”) the values you set in the Parameters Panel.
Constant: Stops the animation.
EaseIn/Out: The graph is horizontal as it leaves the Waypoint.
Linear: The graph of parameter value against time is a straight line.
Undefined: This is only shown for multi-leaf Waypoints, where there is more than one different interpolation type amongst its leaf Waypoints.
Graphical Representation
The color and shape of the Waypoint as displayed in the Timetrack indicates its interpolation type:
Waypoints
Clamped | TCB Smooth | Constant | Ease In/Out | CLinear | Undefined |
Each Waypoint is split into two halves. The left half indicates its In
interpolation and the right half indicates its Out
interpolation, so many different combinations are possible:
In the chart above the In
interpolation is shown on the left, and the Out
interpolation is shown across the top.
Note: the .sif file used to generate these screenshots is available.
Here is an Interpolation.sif
showing 25 different blobs, and how they move with different combinations of Waypoints. It renders to a 634K .avi file, and is available in lower resolution on YouTube. Notice how:
the blobs with any red (Constant) on them don’t move at all
the yellow (Linear) sides of blobs ‘bounce’ off the walls
the cyan (Ease) sides slow gracefully to a halt at the walls
the green (TCB) sides bounce at the top (the animation is a single down-and-up animation, looped, so there’s no ‘context’ at the top for the TCB to fit the curve to) but act smoothly at the bottom
The ‘undefined’ (grey) symbol is used when the row in the Timetrack Panel represents multiple Waypoints. For example, the ‘vertices’ row represents all the vertices making up a Spline. Each of those vertices can have multiple Waypoints, each with different interpolations. If all the interpolations are the same, that interpolation’s symbol will be used. Otherwise, the grey ‘undefined’ symbol is used.
Look at the Waypoints below. They are from the Timetrack for the Vertices
of an Outline Layer.
You’ll see the left side of each of the Waypoints is colored. This means the In
interpolation for each vertex is the same. However, the right side is grey, indicating that the Out
interpolation for each vertex differs.
TODO: rewrite the above so it doesn’t hurt the brain so much.
