Abstract: Examples are provided relating to kinematic joint and chain physics tools for augmented reality implementations. One aspect includes a computing device for kinematic joint simulation, the computing device comprising a display and a processor coupled to a storage system that stores instructions, which, upon execution by the processor, cause the processor to present a chain simulation interface comprising a plurality of graphical control elements, each graphical control element configured to adjust at least one physical parameter, receive a selection from a user using the plurality of graphical control elements, update a chain model based on the received selection, and display and animate the updated chain model on the display using a physics engine during a kinematic motion simulation, wherein the chain model comprises a plurality of rigid body mesh models chained together by spring elements arranged in a tree configuration, to thereby form a rigged skeleton.

Abstract: The present disclosure describes techniques for creating effects based on facial features. A mesh comprising a set of vertices based on detecting key points of at least one facial part may be created. A mask may be created based on rendering the mesh. A filter may be created by applying a function to a texture based on the mask. A portion of at least one image may be extracted based at least in part on the mask. The portion may correspond to the at least one facial part. An effect may be created on the extracted portion using the filter.
