Detailed Description

a seqin an animation.

vtkAnimationCue and vtkAnimationScene provide the framework to support animations in VTK. vtkAnimationCue represents an entity that changes/ animates with time, while vtkAnimationScene represents scene or setup for the animation, which consists on individual cues or other scenes.

A cue has three states: UNINITIALIZED, ACTIVE and INACTIVE. UNINITIALIZED represents an point in time before the start time of the cue. The cue is in ACTIVE state at a point in time between start time and end time for the cue. While, beyond the end time, it is in INACTIVE state. When the cue enters the ACTIVE state, StartAnimationCueEvent is fired. This event may be handled to initialize the entity to be animated. When the cue leaves the ACTIVE state, EndAnimationCueEvent is fired, which can be handled to cleanup after having run the animation. For every request to render during the ACTIVE state, AnimationCueTickEvent is fired, which must be handled to perform the actual animation.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented in vtkAnimationScene.

◆ New()

static vtkAnimationCue * vtkAnimationCue::New ( )

static

◆ SetTimeMode()

virtual void vtkAnimationCue::SetTimeMode ( int mode )

virtual

Get/Set the time mode.

In Normalized mode, the start and end times of the cue are normalized [0,1] with respect to the start and end times of the container scene. In Relative mode the start and end time of the cue are specified in offset seconds relative to the start time of the container scene.

Reimplemented in vtkAnimationScene.

◆ GetTimeMode()

virtual int vtkAnimationCue::GetTimeMode ( )

virtual

Get/Set the time mode.

In Normalized mode, the start and end times of the cue are normalized [0,1] with respect to the start and end times of the container scene. In Relative mode the start and end time of the cue are specified in offset seconds relative to the start time of the container scene.

◆ SetTimeModeToRelative()

void vtkAnimationCue::SetTimeModeToRelative ( )

inline

Get/Set the time mode.

In Normalized mode, the start and end times of the cue are normalized [0,1] with respect to the start and end times of the container scene. In Relative mode the start and end time of the cue are specified in offset seconds relative to the start time of the container scene.

Definition at line 113 of file vtkAnimationCue.h.

◆ SetTimeModeToNormalized()

void vtkAnimationCue::SetTimeModeToNormalized ( )

inline

Get/Set the time mode.

In Normalized mode, the start and end times of the cue are normalized [0,1] with respect to the start and end times of the container scene. In Relative mode the start and end time of the cue are specified in offset seconds relative to the start time of the container scene.

Definition at line 114 of file vtkAnimationCue.h.

◆ SetStartTime()

virtual void vtkAnimationCue::SetStartTime ( double )

virtual

Get/Set the Start time for this cue.

When the current time is >= StartTime, the Cue is in ACTIVE state. if Current time i < StartTime, the Cue is in UNINITIALIZED state. Whenever the cue enters the ACTIVE state from an INACTIVE state, it triggers the StartEvent. The Start time is in seconds relative to the start of the container Scene (when in Relative time mode) or is normalized over the span of the container Scene (when in Normalized time mode).

◆ GetStartTime()

virtual double vtkAnimationCue::GetStartTime ( )

virtual

Get/Set the Start time for this cue.

When the current time is >= StartTime, the Cue is in ACTIVE state. if Current time i < StartTime, the Cue is in UNINITIALIZED state. Whenever the cue enters the ACTIVE state from an INACTIVE state, it triggers the StartEvent. The Start time is in seconds relative to the start of the container Scene (when in Relative time mode) or is normalized over the span of the container Scene (when in Normalized time mode).

◆ SetEndTime()

virtual void vtkAnimationCue::SetEndTime ( double )

virtual

Get/Set the End time for this cue.

When the current time is > EndTime, the Cue is in INACTIVE state. Whenever the cue leaves an ACTIVE state to enter INACTIVE state, the EndEvent is triggered. The End time is in seconds relative to the start of the container Scene (when in Relative time mode) or is normalized over the span of the container Scene (when in Normalized time mode).

◆ GetEndTime()

virtual double vtkAnimationCue::GetEndTime ( )

virtual

Get/Set the End time for this cue.

When the current time is > EndTime, the Cue is in INACTIVE state. Whenever the cue leaves an ACTIVE state to enter INACTIVE state, the EndEvent is triggered. The End time is in seconds relative to the start of the container Scene (when in Relative time mode) or is normalized over the span of the container Scene (when in Normalized time mode).

◆ Tick()

virtual void vtkAnimationCue::Tick	(	double	currenttime,
		double	deltatime,
		double	clocktime
	)

virtual

Indicates a tick or point in time in the animation.

Triggers a Tick event if currenttime >= StartTime and currenttime <= EndTime. Whenever the state of the cue changes, either StartEvent or EndEvent is triggered depending upon whether the cue entered Active state or quit active state respectively. The current time is relative to the start of the container Scene (when in Relative time mode) or is normalized over the span of the container Scene (when in Normalized time mode). deltatime is the time since last call to Tick. deltatime also can be in seconds relative to the start of the container Scene or normalized depending upon the cue's Time mode. clocktime is the time from the scene i.e. it does not depend on the time mode for the cue. For the first call to Tick after a call to Initialize(), the deltatime is 0;

◆ Initialize()

virtual void vtkAnimationCue::Initialize ( )

virtual

Called when the playing of the scene begins.

This will set the Cue to UNINITIALIZED state.

◆ Finalize()

virtual void vtkAnimationCue::Finalize ( )

virtual

Called when the scene reaches the end.

If the cue state is ACTIVE when this method is called, this will trigger a EndAnimationCueEvent.

◆ GetAnimationTime()

virtual double vtkAnimationCue::GetAnimationTime ( )

virtual

This is valid only in a AnimationCueTickEvent handler.

Before firing the event the animation cue sets the AnimationTime to the time of the tick.

◆ GetDeltaTime()

virtual double vtkAnimationCue::GetDeltaTime ( )

virtual

This is valid only in a AnimationCueTickEvent handler.

Before firing the event the animation cue sets the DeltaTime to the difference in time between the current tick and the last tick.

◆ GetClockTime()

virtual double vtkAnimationCue::GetClockTime ( )

virtual

This is valid only in a AnimationCueTickEvent handler.

Before firing the event the animation cue sets the ClockTime to the time of the tick. ClockTime is directly the time from the animation scene neither normalized nor offsetted to the start of the scene.

◆ StartCueInternal()

virtual void vtkAnimationCue::StartCueInternal ( )

protectedvirtual

These are the internal methods that actually trigger they corresponding events.

Subclasses can override these to do extra processing at start/end or on tick.

Reimplemented in vtkAnimationScene.
