Apple patent involves ‘method, system for generating a blended animation’

This illustrates an example operating architecture for generating a blended animation.

Apple has been granted a patent (number US 11593982 B1) for a “method and system for generating a blended animation.” It involves animation and rendering methods, including those involving AR and VR scenes on iPhones, iPads, Macs, and the rumored “RealityPro” headset.

About the patent 

The patent  relates to animation and rendering and, in particular, to systems, devices, and methods for generating a blended animation. Ion the patent Apple notes that a machine learning (ML) system may be able to output coarse joint positions/movements for animating a virtual agent. However, the ML system may not be capable of fine-grained movements, such as facial expressions and the like, which may instead be pre-authored or manually crafted. Apple wants to make it easier to created blended animations.

Summary of the patent

Here’s Apple’s abstract of the patent: “In one implementation, a method for generating a blended animation. The method includes: obtaining a motion input vector for a current time period; generating a motion output vector and pose information for the current time period based on the motion input vector; selecting an animated motion from a bank of animated motions for the current time period that matches the pose information within a threshold tolerance value; obtaining a blending coefficients vector for the current time period; generating a blended animation for the current time period by blending the motion output vector with the animated motion based on the blending coefficients vector; and generating a reward signal for the blended animation for the current time period.”
