Abstract: A computing system and method to implement a three-dimensional virtual reality world with avatar posture animation without user posture tracking devices. A position and orientation of a respective avatar in the virtual reality world is tracked to generate a view of the virtual world for the avatar and to present the avatar to others. In response to input data tracking a position, orientation, and motions of a head of a user of the virtual reality world, the server system uses a posture model to predict, from the input data, a posture of an avatar of the user in the virtual reality world, and computes an animation of the avatar showing the posture of the avatar in the virtual reality world.

Abstract: A computing system and method to generate an avatar wearing multiple layers of clothing. For each clothing model acquired for the avatar, the system generates a customized clothing model based on transforming the original clothing model for fitting on the avatar based on deforming and physical simulation and a reduced clothing model based on collapsing the customized clothing model on the body of the avatar such that applying the reduced clothing model is simplified as painting the texture of the reduced clothing model onto the avatar model. Wearing the inner layers of the clothing by avatar is computed by applying the texture of the corresponding reduced clothing model on the body of the avatar in a sequence from inside layers to outside layers. The customized clothing model of the outermost layer is combined with the avatar wearing the inner layers to generate the avatar wearing the multiple layers of clothing.

Abstract: A computing system and method to implement a three-dimensional virtual reality world with avatar eye movements without user eye tracking. A position and orientation of a respective avatar in the virtual reality world is tracked to generate a view of the virtual world for the avatar and to present the avatar to others. In response to detecting a predetermined event, the computing system predicts a point (e.g., the eye of another avatar) that is of interest to the respective avatar responsive to the event, and computes, according to an eye movement model, an animation of the eyes of the respective avatar where the gaze of the avatar moves from an initial point to the predicted point and/or its vicinity for a period of time and back to the initial point.

Abstract: A computing system and method to generate an avatar wearing a piece of clothing. Given a generic clothing model acquired for the avatar, the system generates a customized clothing model based on uniformly scaling the generic clothing model according to a size of the avatar, identifies one or more edges or boundaries of the clothing, deforms a clothing mesh of the scaled clothing model at the one or more edges by stretching and/or shrinking the edges, and performs a physical simulation of fitting the deformed clothing model on the avatar to generate a fitted clothing model for the avatar. User interfaces can be optionally provided to interactively adjust the scaling, deforming, and/or physical simulation of the clothing models.
