A Physically Based Deformation Model for Interactive Cartoon Animation
نویسندگان
چکیده
We present an approach for automatic cartoon-style motion dramatization suitable for interactive realtime animation. The system is built upon a physically based deformation model previously discussed in [GMPR06] and achieves squash-and-stretch cartoon deformation relevant to the current object velocity by controlling the deformations in the physically based model. As an improvement over previous similar approaches, which largely provide geometrical solutions to the problem, our modified physics-based deformation approach handles more general cases.

Abstract: Nowadays, the animators give life to the fancy characters by making natural movements to organs of cartoon characters. To achieve this goal, movements of living individuals can be applied into cartoon characters. In this paper, a skeletal correspondence finding based method is proposed to transfer movement of a 2D character into a new character, where these two shapes have the same st...
متن کاملInteractive soft-touch dynamic deformations
It is crucial for the users to touch, grasp and manipulate the interested objects through our sense of touch in many interactive applications, such as on-line computer games, interactive cartoon design, and virtual prototyping. In this paper, we propose an interactive haptic deformation approach which incorporates the dynamic simulation of mass–spring systems and flexible control of free-form d...
متن کامل2D shape deformation based on rigid square matching
In this paper, we propose a fast and stable method for 2D shape deformation based on rigid square matching. Our method utilizes uniform quadrangular control meshes for 2D shapes and tries to maintain the rigidity of each square in the control mesh during user manipulation. A rigid shape matching method is performed to find an optimal pure rotational transformation for each square in the control...
متن کاملA simple Mass-Spring system for Character Animation
Mass-Spring systems are used widely to implement animation of deformable objects. We have developed a simple mass-spring system to animate a character based on physics. The reason we adopt a mass-spring system is simply we wanted more realism than Free Form Deformation (FFD) techniques can offer, as modeling physical processes. Also, this technique is preferred over Finite Element Methods (FEM)...
متن کاملPhysically-based Animation of Volumetric Objects
This paper presents a voxel-based animation technique which employs either a massspring model or a nite elementmodel. The voxel-based mesh is generated in a pre-processing step. Two volumetric objects, a voxelized chair and scanned muscle are used as case studies with di erent models. The mass-spring model is used to show an animation sequence of a falling and bouncing chair. Wireframe display ...
