Member Function Documentation

◆ createNumericKeyFrame()

virtual NumericKeyFrame* Ogre::NumericAnimationTrack::createNumericKeyFrame ( Real timePos )

virtual

Creates a new KeyFrame and adds it to this animation at the given time index.

Remarks: It is better to create KeyFrames in time order. Creating them out of order can result in expensive reordering processing. Note that a KeyFrame at time index 0.0 is always created for you, so you don't need to create this one, just access it using getKeyFrame(0);

Parameters

timePos The time from which this KeyFrame will apply.

◆ getInterpolatedKeyFrame()

virtual void Ogre::NumericAnimationTrack::getInterpolatedKeyFrame	(	const TimeIndex &	timeIndex,
		KeyFrame *	kf
	)		const

virtual

Gets a KeyFrame object which contains the interpolated transforms at the time index specified.

Remarks: The KeyFrame objects held by this class are transformation snapshots at discrete points in time. Normally however, you want to interpolate between these keyframes to produce smooth movement, and this method allows you to do this easily. In animation terminology this is called 'tweening'.

Parameters

timeIndex	The time (in relation to the whole animation sequence)
kf	Keyframe object to store results

Implements Ogre::AnimationTrack.

◆ apply()

virtual void Ogre::NumericAnimationTrack::apply	(	const TimeIndex &	timeIndex,
		Real	weight = `1.0`,
		Real	scale = `1.0f`
	)

virtual

Applies an animation track to the designated target.

Parameters

timeIndex	The time position in the animation to apply.
weight	The influence to give to this track, 1.0 for full influence, less to blend with other animations.
scale	The scale to apply to translations and scalings, useful for adapting an animation to a different size target.

Implements Ogre::AnimationTrack.

◆ applyToAnimable()

void Ogre::NumericAnimationTrack::applyToAnimable	(	const AnimableValuePtr &	anim,
		const TimeIndex &	timeIndex,
		Real	weight = `1.0`,
		Real	scale = `1.0f`
	)

Applies an animation track to a given animable value.

Parameters

anim	The AnimableValue to which to apply the animation
timeIndex	The time position in the animation to apply.
weight	The influence to give to this track, 1.0 for full influence, less to blend with other animations.
scale	The scale to apply to translations and scalings, useful for adapting an animation to a different size target.

◆ getAssociatedAnimable()

virtual const AnimableValuePtr& Ogre::NumericAnimationTrack::getAssociatedAnimable ( void ) const

virtual

Returns a pointer to the associated animable object (if any).

◆ setAssociatedAnimable()

virtual void Ogre::NumericAnimationTrack::setAssociatedAnimable ( const AnimableValuePtr & val )

virtual

Sets the associated animable object which will be automatically affected by calls to 'apply'.

◆ getNumericKeyFrame()

NumericKeyFrame* Ogre::NumericAnimationTrack::getNumericKeyFrame ( unsigned short index ) const

Returns the KeyFrame at the specified index.

◆ _clone()

NumericAnimationTrack* Ogre::NumericAnimationTrack::_clone ( Animation * newParent ) const

Clone this track (internal use only)
