Interpolation enumeration

The key frame’s interpolation type.

The Interpolation type exposes the following members:

Field	Description
CONSTANT	The value will remains constant to the value of the first point until the next segment.
LINEAR	Linear interpolation is a straight line between two points.
BEZIER	A bezier or Hermite spline.
B_SPLINE	Basis splines are defined by a series of control points, for which the curve is guaranteed only to go through the first and the last point.
CARDINAL_SPLINE	A cardinal spline is a cubic Hermite spline whose tangents are defined by the endpoints and a tension parameter.
TCB_SPLINE	Also called Kochanek-Bartels spline, the behavior of tangent is defined by tension/bias/continuity
