“…The system however does not generate the skeleton automatically from the given mesh as proposed by Pantuwong.N [Pantuwong and Sugimoto 2012] [Pantuwong and Sugimoto 2011] , Baran. I [ Baran and Popović 2007] and Aujay.G.…”

“…The technique used by Wade [Wade 2000] is to approximate the medial surface by finding discontinuities in the distance field, but they use it to construct a skeleton tree. The proposed algorithm by Pantuwong [Pantuwong and Sugimoto 2012] uses high-curvature boundary voxels to search for a set of critical points and skeleton branches near high-curvature areas.…”

In this research paper we present an automated rigging system for a humanoid (biped) character with complete customization and control options according to the need of the character rigger and the animator. The rigging requirements check list has been proposed for each body part by analyzing various live natural human motions and then summarizing them. The system initially provides widgets that represent human skeletal joints, which can be easily manipulated and modified according to the character type and body height. The system takes the widgets positions from the 3D space and creates the joint based skeletal structure automatically using procedural programming and then followed by creating a complete bipedal rig with custom manipulators to satisfy the animators need in a production environment.

“…The technique used by Wade [7] is to approximate the medial surface by finding discontinuities in the distance field. The proposed algorithm by Pantuwong [8] uses high-curvature boundary voxels to search for a set of critical points and skeleton branches near high-curvature areas. Whereas in a different approach, Pantuwong proposes a technique of automatically generating inverse kinematics based skeleton using skeleton extraction from the volume of character mesh [9].…”

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.
