  • Animation curve reduction for mobile application user interface objects
    Patent number: 9754398
    Abstract: Techniques are described by which the data associated with a 3D animation may be reduced in a manner that does not result in perceptible visual artifacts when the animation is rendered on the display of a target device. Animation curve reduction is achieved by the removal of redundant animation curve samples, and is independently guided for different object attributes or animation channels by the nature of the attribute and one or more display parameters of the target device for which the animation is intended.
