Member Function Documentation

AddTime()

void AddTime ( double  _time )

inherited

Add time to the animation.

Parameters

[in]

_time

The amount of time to add in seconds

CreateKeyFrame()

NumericKeyFrame* CreateKeyFrame

(

double

_time

)

Create a numeric keyframe at the given time.

Parameters

[in]

_time

Time at which to create the keyframe

Returns

Pointer to the new keyframe

GetInterpolatedKeyFrame()

void GetInterpolatedKeyFrame

(

NumericKeyFrame &

_kf

)

const
