virtual void Ogre::AnimationTrack::_buildKeyFrameIndexMap ( const vector< Real >::type & keyFrameTimes )

virtualinherited

Internal method to build keyframe time index map to translate global lower bound index to local lower bound index.

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

Clone this track (internal use only)

virtual void Ogre::AnimationTrack::_collectKeyFrameTimes ( vector< Real >::type & keyFrameTimes )

virtualinherited

Internal method to collect keyframe times, in unique, ordered format.

virtual void Ogre::AnimationTrack::_keyFrameDataChanged ( void ) const

inlinevirtualinherited

Internal method used to tell the track that keyframe data has been changed, which may cause it to rebuild some internal data.

Reimplemented in Ogre::NodeAnimationTrack.

Definition at line 215 of file OgreAnimationTrack.h.

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.

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.

virtual KeyFrame* Ogre::AnimationTrack::createKeyFrame ( Real timePos )

virtualinherited

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.

KeyFrame* Ogre::NumericAnimationTrack::createKeyFrameImpl ( Real time )

protectedvirtual

Create a keyframe implementation - must be overridden.

Implements Ogre::AnimationTrack.

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.

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

virtual

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

unsigned short Ogre::AnimationTrack::getHandle ( void ) const

inlineinherited

Get the handle associated with this track.

Definition at line 145 of file OgreAnimationTrack.h.

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.

virtual KeyFrame* Ogre::AnimationTrack::getKeyFrame ( unsigned short index ) const

virtualinherited

Returns the KeyFrame at the specified index.

virtual Real Ogre::AnimationTrack::getKeyFramesAtTime	(	const TimeIndex &	timeIndex,
		KeyFrame **	keyFrame1,
		KeyFrame **	keyFrame2,
		unsigned short *	firstKeyIndex = `0`
	)		const

virtualinherited

Gets the 2 KeyFrame objects which are active at the time given, and the blend value between them.

Remarks: At any point in time in an animation, there are either 1 or 2 keyframes which are 'active', 1 if the time index is exactly on a keyframe, 2 at all other times i.e. the keyframe before and the keyframe after.

: This method returns those keyframes given a time index, and also returns a parametric value indicating the value of 't' representing where the time index falls between them. E.g. if it returns 0, the time index is exactly on keyFrame1, if it returns 0.5 it is half way between keyFrame1 and keyFrame2 etc.

Parameters

timeIndex	The time index.
keyFrame1	Pointer to a KeyFrame pointer which will receive the pointer to the keyframe just before or at this time index.
keyFrame2	Pointer to a KeyFrame pointer which will receive the pointer to the keyframe just after this time index.
firstKeyIndex	Pointer to an unsigned short which, if supplied, will receive the index of the 'from' keyframe in case the caller needs it.

Returns: Parametric value indicating how far along the gap between the 2 keyframes the timeIndex value is, e.g. 0.0 for exactly at 1, 0.25 for a quarter etc. By definition the range of this value is: 0.0 <= returnValue < 1.0 .

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

Returns the KeyFrame at the specified index.

virtual unsigned short Ogre::AnimationTrack::getNumKeyFrames ( void ) const

virtualinherited

Returns the number of keyframes in this animation.

Animation* Ogre::AnimationTrack::getParent ( ) const

inlineinherited

Returns the parent Animation object for this track.

Definition at line 237 of file OgreAnimationTrack.h.

virtual bool Ogre::AnimationTrack::hasNonZeroKeyFrames ( void ) const

inlinevirtualinherited

Method to determine if this track has any KeyFrames which are doing anything useful - can be used to determine if this track can be optimised out.
