Detailed Description

An animation sequence.

Remarks: This class defines the interface for a sequence of animation, whether that be animation of a mesh, a path along a spline, or possibly more than one type of animation in one. An animation is made up of many 'tracks', which are the more specific types of animation.

: You should not create these animations directly. They will be created via a parent object which owns the animation, e.g. Skeleton.

◆ setInterpolationMode()

void Ogre::Animation::setInterpolationMode ( InterpolationMode im )

Tells the animation how to interpolate between keyframes.

Remarks: By default, animations normally interpolate linearly between keyframes. This is fast, but when animations include quick changes in direction it can look a little unnatural because directions change instantly at keyframes. An alternative is to tell the animation to interpolate along a spline, which is more expensive in terms of calculation time, but looks smoother because major changes in direction are distributed around the keyframes rather than just at the keyframe.

: You can also change the default animation behaviour by calling Animation::setDefaultInterpolationMode.

Gets the current interpolation mode of this animation.

Remarks: See setInterpolationMode for more info.

◆ setRotationInterpolationMode()

void Ogre::Animation::setRotationInterpolationMode ( RotationInterpolationMode im )

Tells the animation how to interpolate rotations.

Remarks: By default, animations interpolate linearly between rotations. This is fast but not necessarily completely accurate. If you want more accurate interpolation, use spherical interpolation, but be aware that it will incur a higher cost.

: You can also change the default rotation behaviour by calling Animation::setDefaultRotationInterpolationMode.

◆ getRotationInterpolationMode()

RotationInterpolationMode Ogre::Animation::getRotationInterpolationMode ( void ) const

Gets the current rotation interpolation mode of this animation.

Remarks: See setRotationInterpolationMode for more info.

static

Gets the default interpolation mode for all animations.

◆ setDefaultRotationInterpolationMode()

static void Ogre::Animation::setDefaultRotationInterpolationMode ( RotationInterpolationMode im )

◆ getVertexTrackIterator()

◆ optimise()

void Ogre::Animation::optimise ( bool discardIdentityNodeTracks = true )

Optimise an animation by removing unnecessary tracks and keyframes.

Remarks: When you export an animation, it is possible that certain tracks have been keyframed but actually don't include anything useful - the keyframes include no transformation. These tracks can be completely eliminated from the animation and thus speed up the animation. In addition, if several keyframes in a row have the same value, then they are just adding overhead and can be removed.

Note: Since track-less and identity track has difference behavior for accumulate animation blending if corresponding track presenting at other animation that is non-identity, and in normally this method didn't known about the situation of other animation, it can't deciding whether or not discards identity tracks. So there have a parameter allow you choose what you want, in case you aren't sure how to do that, you should use Skeleton::optimiseAllAnimations instead.

Parameters

discardIdentityNodeTracks If true, discard identity node tracks.

◆ _collectIdentityNodeTracks()

void Ogre::Animation::_collectIdentityNodeTracks ( TrackHandleList & tracks ) const

Remarks: This method remove non-identity node tracks form the track handle list.

◆ _destroyNodeTracks()

void Ogre::Animation::_destroyNodeTracks ( const TrackHandleList & tracks )

Internal method for destroy given node tracks.

◆ clone()

Animation* Ogre::Animation::clone ( const String & newName ) const

Clone this animation.

Note: The pointer returned from this method is the only one recorded, thus it is up to the caller to arrange for the deletion of this object.

◆ _keyFrameListChanged()

void Ogre::Animation::_keyFrameListChanged ( void )

inline

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

◆ _getTimeIndex()

TimeIndex Ogre::Animation::_getTimeIndex ( Real timePos ) const

Internal method used to convert time position to time index object.

Note: The time index returns by this function are associated with state of the animation object, if the animation object altered (e.g. create/remove keyframe or track), all related time index will invalidated.

Parameters

timePos The time position.

Returns: The time index object which contains wrapped time position (in relation to the whole animation sequence) and lower bound index of global keyframe time list.

◆ setUseBaseKeyFrame()

void Ogre::Animation::setUseBaseKeyFrame	(	bool	useBaseKeyFrame,
		Real	keyframeTime = `0.0f`,
		const String &	baseAnimName = `BLANKSTRING`
	)

Sets a base keyframe which for the skeletal / pose keyframes in this animation.

Remarks: Skeletal and pose animation keyframes are expressed as deltas from a given base state. By default, that is the binding setup of the skeleton, or the object space mesh positions for pose animation. However, sometimes it is useful for animators to create animations with a different starting pose, because that's more convenient, and the animation is designed to simply be added to the existing animation state and not globally averaged with other animations (this is always the case with pose animations, but is activated for skeletal animations via ANIMBLEND_CUMULATIVE).

: In order for this to work, the keyframes need to be 're-based' against this new starting state, for example by treating the first keyframe as the reference point (and therefore representing no change). This can be achieved by applying the inverse of this reference keyframe against all other keyframes. Since this fundamentally changes the animation, this method just marks the animation as requiring this rebase, which is performed at the next Animation 'apply' call. This is to allow the Animation to be re-saved with this flag set, but without having altered the keyframes yet, so no data is lost unintentionally. If you wish to save the animation after the adjustment has taken place, you can (

Parameters

useBaseKeyFrame	Whether a base keyframe should be used
keyframeTime	The time corresponding to the base keyframe, if any
