Interpolation is a way of constructing new data points within a range of known data points.

The range of applications is varied, but here in SL it can most directly be used for animating and/or moving prims or linksets via any attribute you can creatively make use of.

Attributes:

Prim/Object Position
Prim/Object Rotation
Texture Scale/Offsets
or you can just simply interpolate internal values

Potential applications:

Movement
Animation
User Interfaces
Graphics
Games

There are many different types of interpolation, which may exhibit different preferred or controllable behaviour.
