VelocityOrientationProperty
open external class VelocityOrientationProperty(position: PositionProperty? = definedExternally, ellipsoid: Ellipsoid? = definedExternally)(source)
A Property which evaluates to a Quaternion rotation based on the velocity of the provided PositionProperty.
//Create an entity with position and orientation.
const position = new SampledProperty();
position.addSamples(...);
