Character rigging is a process of endowing a character with a set of custom manipulators and controls making it easy to animate by the animators. These controls consist of simple joints, handles, or even separate character selection windows. This research paper present an automated rigging system for quadruped characters with custom controls and manipulators for animation. The full character rigging mechanism is procedurally driven based on various principles and requirements used by the riggers and animators. The automation is achieved initially by creating widgets according to the character type. These widgets then can be customized by the rigger according to the character shape, height and proportion. Then joint locations for each body parts are calculated and widgets are replaced programmatically. Finally a complete and fully operational procedurally generated character control rig is created and attached with the underlying skeletal joints. The functionality and feasibility of the rig was analyzed from various source of actual character motion and a requirements criterion was met. The final rigged character provides an efficient and easy to manipulate control rig with no lagging and at high frame rate.

In this paper a unique way of rigging a bipedal character is discussed inside 3Ds Max, using constraints, wire parameter setup and linking the controls. 3Ds Max is more commonly used for game character modeling and rigging. For this purpose a built-in Biped setup is present that is a pre-rigged structure, which can be easily applied on any bipedal character type easily and efficiently. However, the built-in Biped system lacks the functionality of manual control and motion retargeted manipulation, mostly found in custom rigs. This proposed system builds a custom rig using a unique approach of combining multiple tools and expressions.
