Member Function Documentation

◆ getAnimationType()

VertexAnimationType Ogre::VertexAnimationTrack::getAnimationType ( void ) const

inline

Get the type of vertex animation we're performing.

◆ getVertexAnimationIncludesNormals()

bool Ogre::VertexAnimationTrack::getVertexAnimationIncludesNormals ( ) const

Whether the vertex animation (if present) includes normals.

◆ createVertexMorphKeyFrame()

virtual VertexMorphKeyFrame* Ogre::VertexAnimationTrack::createVertexMorphKeyFrame ( Real timePos )

virtual

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

It is better to create KeyFrames in time order.

Parameters

timePos The time from which this KeyFrame will apply.

◆ createVertexPoseKeyFrame()

virtual VertexPoseKeyFrame* Ogre::VertexAnimationTrack::createVertexPoseKeyFrame ( Real timePos )

virtual

Creates the single pose KeyFrame and adds it to this animation.

◆ getInterpolatedKeyFrame()

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

overridevirtual

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

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()

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

overridevirtual

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.

◆ applyToVertexData()

virtual void Ogre::VertexAnimationTrack::applyToVertexData	(	VertexData *	data,
		const TimeIndex &	timeIndex,
		float	weight = `1.0`,
		const PoseList *	poseList = `0`
	)

virtual

As the 'apply' method but applies to specified VertexData instead of associated data.

◆ getVertexMorphKeyFrame()

VertexMorphKeyFrame* Ogre::VertexAnimationTrack::getVertexMorphKeyFrame ( unsigned short index ) const

Returns the morph KeyFrame at the specified index.

◆ getVertexPoseKeyFrame()

VertexPoseKeyFrame* Ogre::VertexAnimationTrack::getVertexPoseKeyFrame ( unsigned short index ) const

Returns the pose KeyFrame at the specified index.

◆ setAssociatedVertexData()

void Ogre::VertexAnimationTrack::setAssociatedVertexData ( VertexData * data )

inline

Sets the associated VertexData which this track will update.

◆ getAssociatedVertexData()

VertexData* Ogre::VertexAnimationTrack::getAssociatedVertexData ( void ) const

inline

Gets the associated VertexData which this track will update.

◆ setTargetMode()

void Ogre::VertexAnimationTrack::setTargetMode ( TargetMode m )

inline

Set the target mode.

◆ getTargetMode()

TargetMode Ogre::VertexAnimationTrack::getTargetMode ( void ) const

inline

Get the target mode.

◆ hasNonZeroKeyFrames()

bool Ogre::VertexAnimationTrack::hasNonZeroKeyFrames ( void ) const

overridevirtual

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.

Reimplemented from Ogre::AnimationTrack.

◆ optimise()

void Ogre::VertexAnimationTrack::optimise ( void )

overridevirtual

Optimise the current track by removing any duplicate keyframes.

Reimplemented from Ogre::AnimationTrack.

◆ _clone()

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

Clone this track (internal use only)

◆ _applyBaseKeyFrame()

void Ogre::VertexAnimationTrack::_applyBaseKeyFrame ( const KeyFrame * base )

overridevirtual

Internal method to re-base the keyframes relative to a given keyframe.

Reimplemented from Ogre::AnimationTrack.
