void AltusUnified::AnimationManager::animateTransformAroundEarth	(	Transform	transform,
		Transform	newTransform,
		double	animationDuration
	)

Animate the camera in an orbital path between two transforms (locations, orientations, and size). This can be used to animate an object along the great circle between to locations.

Parameters

transform	The starting transform.
newTransform	The new transform.
animationDuration	Length of time in seconds to perform the animation.

void AltusUnified::AnimationManager::continuallyLookAt	(	Transform	transform,
		Transform	target
	)

A perpetual animation that forces an object to always face another object.

Parameters

transform	The transform to rotate (typically for an object like the camera).
target	The object that transform should always face.

void AltusUnified::AnimationManager::orbitAroundAxis	(	Transform	transform,
		vec3d	center,
		vec3d	axis,
		double	rateRadiansPerSecond,
		double	momentum,
		double	rateLimit
	)

Rotate an object around a point while keeping the object pointed at the point. Use this when you want to rotate an object as if it has friction. Rotational velocity is non-linear: when momentum is not 1, exponential decay is performed with a base of (1.0 - momentum).

Parameters

transform	The transform to move (typically for an object like the camera).
center	The point around which to orbit.
axis	The axis of rotation (which direction to orbit around the point).
rateRadiansPerSecond	How fast to orbit in radians/second.
momentum	The percentage of rotational velocity to maintain every second. A value of 1 means indefinite rotation, and 0 means no rotation after 1 second.
rateLimit	The rotational velocity, in radians/second, at which to stop the animation. A small, positive value is typically used here.

void AltusUnified::AnimationManager::orbitAroundPoint	(	Transform	transform,
		GeographicPosition	point,
		double	rateRadiansPerSecond,
		double	accelRadiansPerSecondPerSecond,
		double	animationDuration
	)

Rotate an object around a point while keeping the object pointed at the point. The axis of rotation is the line pointing "up" from the Earth, passing through the point. This can be used to rotate the camera round a point while keeping the point at the same screen position.

Parameters

transform	The transform to move (typically for an object like the camera).
point	The point around which to orbit.
rateRadiansPerSecond	How fast to orbit in radians/second.
accelRadiansPerSecondPerSecond	Acceleration rate.
animationDuration	Length of time in seconds which to perform the orbit.

void AltusUnified::AnimationManager::orbitAroundTransform	(	Transform	transform,
		Transform	center,
		double	rateRadiansPerSecond,
		double	accelRadiansPerSecondPerSecond,
		double	animationDuration
	)

Rotate an object around a point while keeping the object pointed at the point. The axis of rotation is determined by the center's up vector. This can be used to rotate the camera round a point while keeping the point at the same screen position.

Parameters

transform	The transform to move (typically for an object like the camera).
center	The point around which to orbit.
rateRadiansPerSecond	How fast to orbit in radians/second.
accelRadiansPerSecondPerSecond	Acceleration rate.
animationDuration	Length of time in seconds which to perform the orbit.

void AltusUnified::AnimationManager::stopAnimations
