ID3DXKeyFrameInterpolator Interface

This interface implements an interpolator.

ID3DXKeyFrameInterpolator Members

GetLastSRT	Returns the previous scale, rotation, and translation values.
GetName	Gets the name of the interpolator.
GetNumRotationKeys	Returns the number of rotation key frames.
GetNumScaleKeys	Returns the number of scale key frames.
GetNumTranslationKeys	Returns the number of translation key frames.
GetPeriod	Gets the interpolator period.
GetRotationKeys	Returns an array of rotation values.
GetScaleKeys	Returns an array of scale values.
GetSourceTicksPerSecond	Returns the time scale factor passed to D3DXCreateKeyFrameInterpolator. This value is used to scale local time to global (or application) time.
GetSRT	Returns the scale, rotation, and translation at a given time.
GetTranslationKeys	Returns an array of translation vectors.

Remarks

Interpolators are the basic building blocks for animation. Each interpolator defines the scale, rotate, and translation values at a unique point in time. Scale and rotation values are stored as vectors, rotations are stored as quaternions.
