Nvidia patents AI method to make digital characters move realistically
Nvidia has been granted a patent for a system that uses neural networks to create images of characters performing actions. The technology uses a 'character graph' to track a character's physical limits and current state, ensuring the generated movements look natural and physically possible rather than robotic.
In the filing’s own words
Apparatuses, systems, and techniques are presented to generate images representing realistic motion or activity. In at least one embodiment, one or more neural networks are used to generate one or more images of one or more characters performing one or more actions based, at least in part, upon one or more physical capabilities of the one or more characters.
What exactly they claim (claim 1)
1. A processor, comprising: one or more circuits to: cause one or more neural networks to generate one or more actions of one or more characters based, at least in part, on: propagating respective information between adjacent nodes of a character graph to update respective information of the adjacent nodes of a given character graph of the one or more characters, wherein the respective information of an individual node of the adjacent nodes for a given character graph of the one or more characters indicates: one or more physical capabilities for the one or more characters; a current state for the individual node for the given character graph; and a target state for the individual node for the given character graph; and; cause a rendering of one or more images depicting a performance of the one or more actions based, at least in part, on the updated respective information of the adjacent nodes of the given character graph, wherein the one or more actions depicted in the one or more images are performed according to the one or more physical capabilities of the one or more characters to perform the one or more actions.
