Efficient Muscle Shape Deformation
نویسندگان
چکیده
In this paper we extend previous work [Aubel00] and propose a muscle model suitable for computer graphics based on physiological and anatomical considerations. Muscle motion and deformation is automatically derived from an action line that is deformed using a 1D mass-spring system. The resulting model is fast and can accommodate most superficial human muscles.

Simulating Skin Deformation Using Anatomical Structure, Muscle Dynamics, and Soft Tissue Dynamics
1 Movement of skin and muscle is essential for bringing a character to 2 life. This movement is difficult to animate in a realistic fashion us3 ing traditional techniques because of the subtle details required. In 4 this paper, we present an algorithm that generates natural, dynamic, 5 and detailed skin deformation from standard motion capture joint 6 angle data. The algorithm consists of two s...
متن کاملSEISMIC OPTIMIZATION OF STEEL SHEAR WALL USING SHAPE MEMORY ALLOY
Nowadays, steel shear walls are used as efficient lateral-load-resistant systems due to their high lateral stiffness and carrying capacity. In this paper, the effect of substituting a shape memory alloy (SMA) material is investigated instead of using conventional steel in the shear wall. A numerical study is conducted using finite element method (FEM) by OpenSees software. For this purpose, at ...
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 کاملShape-aware as rigid as possible deformation
We propose a formulation capable of deforming meshes in a shape-sensible way. We explain how to adapt the original space-deforming algorithm [2] into a skeleton-driven deformation scheme, where more sensitivity to the mesh geometry is achieved. The more natural results make it possible to use the technique for character animation.
متن کاملThe Deformation Rate of Smooth Muscle Cells in Vessel Walls After Short-Duration Heating Dilatation in a Porcine Model Ex Vivo and In Vivo
We have proposed a novel short-duration thermal angioplasty with uniform temperature distribution. Although the dilatation mechanism of our short-duration heating dilatation was reported in our previous study, the influences on smooth muscle cells (SMCs) are not sufficiently understood. We studied the influences on SMCs in terms of shape change and discussed the relationship between the SMCs' s...
