Class represents a basic animation class. AIS_Animation can be used as:
Note, that AIS_Animation::StartTimer() defines a timer calculating an elapsed time, not a multimedia timer executing Viewer updates at specific intervals! Application should avoid using implicit and immediate Viewer updates to ensure that AIS_Animation::UpdateTimer() is called before each redrawing of a Viewer content. Redrawing logic should be also managed at application level for managing a smooth animation (by defining a multimedia timer provided by used GUI framework executing updates at desired framerate, or as continuous redraws in loop).

|
virtual |
Start animation with internally defined timer instance. Calls ::Start() internally.
Note, that this method initializes a timer calculating an elapsed time (presentation timestamps within AIS_Animation::UpdateTimer()), not a multimedia timer executing Viewer updates at specific intervals! Viewer redrawing should be managed at application level, so that AIS_Animation::UpdateTimer() is called once right before each redrawing of a Viewer content.

thePlaySpeed | playback speed (1.0 means normal speed) |
theToUpdate | flag to update defined animations to specified start position |
theToStopTimer | flag to pause timer at the starting position |
|
virtual |
Stop animation. This method changed status of the animation to Stopped. This status shows that animation will not be performed in the timeline or it is finished.
|
inline |
Return playback timer.
