US 10,311,621 B2 · Held object stabilization in virtual reality

Abstract

Techniques of animating objects in VR involve applying a motion filter to the object that varies with vertices on an object. Along these lines, a VR computer generates an object for an interactive, three-dimensional game by generating a triangular mesh approximating the object surface and bones including vertices defining motion of the vertices based on motion of an anchor vertex. When a user selects a vertex of the object as an anchor vertex about which to move the object, the VR computer generates variable filters for each bone that restrict the motion of that bone based on the distance of that bone from the anchor vertex. Accordingly, when the user produces a gesture with a controller that defines a path of motion for the anchor vertex, the bone including the anchor vertex goes through an unfiltered motion while bones remote from the anchor vertex go through a more restricted motion.
