Detailed Description

Interpolator representation.

A interpolator is a function whose domain is [0..1] and range is [0..1]. It is used to describe how a DOF (see Dof) should be changed in time inside an animation (see Action).

Member Function Documentation

virtual TypeID VART::Interpolator::GetID ( ) const

pure virtual

Implemented in VART::HermiteInterpolator, VART::SineInterpolator, and VART::LinearInterpolator.

virtual float VART::Interpolator::GetValue ( float  linearIndex, float  initialPos, float  range  ) const

pure virtual

Evaluates a goal position for DOF interpolation.

Parameters

linearIndex	[in] A number in range [0..1]. Usually related to a linear time function.
initialPos	[in] A number in range [0..1]. DOF's initial movement position.
range	[in] DOF's position range on movement.

Returns

DOF's current position. An interpolator basically converts a linear interpolation (GetValue input) into other, more sophisticated interpolation (GetValue output). Each derived class implents a specific mapping.

Implemented in VART::NaturalInterpolator, VART::HermiteInterpolator, VART::RangeSineInterpolator, VART::SineInterpolator, and VART::LinearInterpolator.
