Rendering a three-dimensional model comprised of three-dimensional data defining a bone and a polygon includes determining a location of a vertex of the polygon relative to the bone, transforming the vertex based on the location to produce a transformed vertex, and rendering the three-dimensional model using the transformed vertex. A multiple menu comprises a menu panel with two or more selection regions, each of which is associated with a base menu. The fan is for generating airflow. The eNB also transmits physical layer signaling indicating a subframe conversion for the target downlink subframe if it is determined to convert the target downlink subframe to the special subframe type 2. A smart icon graphical user interface is utilized, that automatically toggles between locked and unlocked depending on if the computing device is at risk or not, to place the computing device in a protected or unprotected mode.
