Boneless Pose Editing and Animation

Abstract. In this paper, we propose a pose editing and animation method for triangulated surfaces based on a user controlled partitioning of the model into deformable parts and rigid parts which are denoted handles. In our pose editing system, the user can sculpt a set of poses simply by transforming the handles for each pose. Using Laplacian editing, the deformable parts are deformed to match the handles. In our animation system the user can constrain one or several handles in order to define a new pose. New poses are interpolated from the examples poses, by solving a small non-linear optimization problem in order to obtain the interpolation weights. While the system can be used simply for building poses, it is also an animation system. The user can specify a path for a given constraint and the model is animated correspondingly.

Le Couple

LE COUPLE is an animated graduate thesis film with a total timescale of 6 minutes and 40 seconds. The intent of LE COUPLE is to talk about a story of love, but not in a clichéd manner. Since Jieting Chen and I worked together before, we have a very strong personal connection. As usual, we wanted to make the film into a comedy. The film is a hand-drawn animation that was produced primarily in TVPaint Animation Software. This paper outlines the entire film creation process from my point of view. It details the very beginning of the story development to the final moments of finishing the film. It describes all my intentions, obstacles, failures and successes, as well as technical specifics of process

Stokes Coordinates

Cage-based structures are reduced subspace deformers enabling non-isometric stretching deformations induced by clothing or muscle bulging. In this paper, we reformulate the cage-based rigging as an incompressible Stokes problem in the vorticity space. The key to our approach is a compact stencil allowing the expression of fluid-inspired high-order coordinates. Thus, our cage-based coordinates are obtained by vorticity transport as the numerical solution of the linearized Stokes equations. Then, we turn the incompressible creeping Newtonian flow into Stokes equations, and we devise a second-order compact approximation with center differencing for solving the vorticity-stream function. To the best of our knowledge, our work is the first to devise a vorticity-stream function formulation as a computational model for cage-based weighting functions. Finally, we demonstrate the effectiveness of our new techniques for a collection of cage-based shapes and applications

Procedural animation: towards studio solutions for believability

This thesis sets out to investigate the understanding of the relationship between key-frame movement performances and procedural animation. It is geared towards building a theory of practice that would help develop a succinct method for generating believable character animation using procedural animation. This research places an emphasis on a practical aproach to the theory of animation and movement, and investigates the historical development of character animation and the notion of believability. It uses Laban Movement Analysis as a method in the application of procedural animation. The study seeks to address the following objectives: (1) To examine what areas of procedural animation may enhance the believability of a key-framed movement performance; (2) To identify the areas of procedural animation that are or could be used within professional studio practice; (3) To examine the potential of procedural animation to help develop convincing and life-like character movements; (4) To identify where and how a keyframed character movement can be enhanced procedurally; (5) To carry out empirical studies in order to analyse the effects and possible benefits of procedural enhancements on a key-framed movement
