Detailed Description

Interface for tracks in an animation. A track usually represent a value to be animated over time and contains a list of KeyFrameSequence. The value will only be animated when the time in the animation is within a KeyFrameSequence in the Track.

A Track has additional metadata information, such as (display) Name, Enabled, Priority. Tracks are listed in order based on their priority.

Constructor & Destructor Documentation

◆ ~Track()

virtual inviwo::animation::Track::~Track ( )

virtualdefault

Remove all keyframe sequences and call TrackObserver::notifyKeyframeSequenceRemoved

Member Function Documentation

◆ add() [1/2]

virtual Keyframe * inviwo::animation::Track::add	(	Seconds	time,
		bool	asNewSequence )

pure virtual

Add a Keyframe at time and return the added keyframe. The Keyframe is added to a new KeyframeSequence if asNewSequence is true, otherwise it should be added to the closest KeyframeSequence at specified time. A KeyframeSequence is added to the Track if none exists.
