add
Creates and adds an animation with the specified initial properties to the collection.
This raises the ModelAnimationCollection.animationAdded event so, for example, a UI can stay in sync.

model.activeAnimations.add({
name : 'animation name'

// Example 2. Add an animation by index

// Example 3. Add an animation and provide all properties and events
const startTime = JulianDate.now();
const animation = model.activeAnimations.add({
name : 'another animation name',
startTime : startTime,
delay : 0.0, // Play at startTime (default)
stopTime : JulianDate.addSeconds(startTime, 4.0, new JulianDate()),
removeOnStop : false, // Do not remove when animation stops (default)
multiplier : 2.0, // Play at double speed
reverse : true, // Play in reverse
loop : ModelAnimationLoop.REPEAT // Loop the animation
});
