Abstract: A database stores unique associations between account identifiers and mobile-network telephone numbers assigned by a mobile network to mobile communications devices. The account identifiers are also associated with voice-over-IP (VoIP) telephone numbers. Voice calls between the mobile communications devices are made as voice-over-IP (VoIP) calls using respective VoIP telephone numbers. Tracking of the VoIP calls is performed through the mobile network using respective mobile-network telephone numbers, so that a prepaid balance can be enforced.

Abstract: An augmented reality (AR) application enables customization and manipulation of three dimensional (3D) avatars on a mobile client. The application provides a variety of options for modifying the physical appearance of an avatar, including base features such as skin tone and body shape. When a user adjusts these base features, application may make corresponding adjustments to part features (e.g., clothing items) that are displayed over the base features. The application provides the customized avatars for display, including in performances of animations (e.g., dances). The application enables interactive cameras such as smooth panning and zooming for a user to see their customized avatar from various angles. The application renders depth of the 3D using shaders optimized for use on a mobile client. The shaders may reuse framebuffers on an as-needed basis. The application renders shading that accounts for both virtual and physical light sources.
