System and method are provided for achieving 'inverse kinematics' of 3D graphics depicting an object that consists of multiple parts. The system displays an animation of a 3D graphics object that consists of multiple moving parts. The animation is associated with an animation timeline defined by two end points&#x2014;a starting time point and an ending time point. The user can manipulate the object back and forth along the animation timeline, between the two end points, by selecting (e.g., clicking on) and moving (dragging) any of the movable parts of the object on a display screen. In short, the user can use any of the movable parts as a scroll/slide button to move the animation forward and backward along the animation timeline, to achieve real-time inverse kinematics movement.

Method and system for emulating inverse kinematics

System and method are provided for building and rendering a 3D graphics dataset of an object that consists of multiple parts, wherein the 3D graphics dataset includes a 3D geometry dataset and a configuration file, and in the configuration file each of the multiple parts is identified as used (e.g., visible, actionable) or unused (e.g., not visible, not actionable) in each of multiple display features (e.g., in display states, such as in animations, or in display relationships). The method determines which of the multiple parts are unused in each of the multiple display features and identifies those parts, which are unused in all of the display features, as excluded parts, and saves a list of the identified excluded parts in association with the object. In rendering the object on a display, the method does not load data directed to the excluded parts, to thereby speed up the loading/rendering process.
