Member Function Documentation

◆ _applyBaseKeyFrame()

void Ogre::v1::NodeAnimationTrack::_applyBaseKeyFrame ( const KeyFrame base)
virtual

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

Reimplemented from Ogre::v1::AnimationTrack.

◆ _buildKeyFrameIndexMap()

virtual void Ogre::v1::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.

◆ _clone()

NodeAnimationTrack * Ogre::v1::NodeAnimationTrack::_clone ( Animation newParent) const

Clone this track (internal use only)

◆ _collectKeyFrameTimes()

virtual void Ogre::v1::AnimationTrack::_collectKeyFrameTimes ( vector< Real >::type &  keyFrameTimes)
virtualinherited

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

◆ _keyFrameDataChanged()

void Ogre::v1::NodeAnimationTrack::_keyFrameDataChanged ( void  ) const
virtual

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

Reimplemented from Ogre::v1::AnimationTrack.

◆ apply()

virtual void Ogre::v1::NodeAnimationTrack::apply ( const TimeIndex timeIndex,
Real  weight = 1.0,
Real  scale = 1.0f 
)
virtual

Applies an animation track to the designated target.

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

Implements Ogre::v1::AnimationTrack.

◆ applyToNode()

void Ogre::v1::NodeAnimationTrack::applyToNode ( Node node,
const TimeIndex timeIndex,
Real  weight = 1.0,
Real  scale = 1.0f 
)

As the 'apply' method but applies to a specified OldNode instead of associated node.

◆ createKeyFrame()

virtual KeyFrame * Ogre::v1::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
timePosThe time from which this KeyFrame will apply.

◆ createNodeKeyFrame()

virtual TransformKeyFrame * Ogre::v1::NodeAnimationTrack::createNodeKeyFrame ( 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
timePosThe time from which this KeyFrame will apply.

◆ getAssociatedNode()

Node * Ogre::v1::NodeAnimationTrack::getAssociatedNode ( void  ) const

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

◆ getHandle()

unsigned short Ogre::v1::AnimationTrack::getHandle ( void  ) const
inlineinherited

Get the handle associated with this track.

Referenced by Ogre::Lod0Stripifier::StripLod0Vertices().

◆ getInitialState()

void Ogre::v1::NodeAnimationTrack::getInitialState ( Vector3 outPosition,
Quaternion outOrientation,
Vector3 outScale 
)

Get the initial state of the node for this track.

Remarks
Node tracks are based from an initial state, which the node is set to every frame before the node animation is applied See NodeAnimationTrack::getInitialState for more information

◆ getInterpolatedKeyFrame()

virtual void Ogre::v1::NodeAnimationTrack::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
timeIndexThe time (in relation to the whole animation sequence)
kfKeyframe object to store results

Implements Ogre::v1::AnimationTrack.

◆ getKeyFrame()

virtual KeyFrame * Ogre::v1::AnimationTrack::getKeyFrame ( unsigned short  index) const
virtualinherited

Returns the KeyFrame at the specified index.

◆ getKeyFramesAtTime()

virtual Real Ogre::v1::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
timeIndexThe time index.
keyFrame1Pointer to a KeyFrame pointer which will receive the pointer to the keyframe just before or at this time index.
keyFrame2Pointer to a KeyFrame pointer which will receive the pointer to the keyframe just after this time index.
firstKeyIndexPointer 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 .

◆ getNodeKeyFrame()

virtual TransformKeyFrame * Ogre::v1::NodeAnimationTrack::getNodeKeyFrame ( unsigned short  index) const
virtual

Returns the KeyFrame at the specified index.

◆ getNumKeyFrames()

virtualinherited

Returns the number of keyframes in this animation.

virtual

Gets the method of rotation calculation.

◆ hasNonZeroKeyFrames()

virtual bool Ogre::v1::NodeAnimationTrack::hasNonZeroKeyFrames ( void  ) const
virtual

◆ resetNodeToInitialState()

void Ogre::v1::NodeAnimationTrack::resetNodeToInitialState ( void  )

Resets the the target node to the initial state.
