| Abstract;The calculation of spring model deformation is so fast that it is often used for string shaped objects such as human hair, noodles and blood vessels. However, the model can be applied only to very small deformation. In large deformation, there is sometimes no solution due to zero determinant of the stiffness matrix and the result of the deformation is not correct. Therefore, we propose a new method that can solve the stiffness equation stably by adding extra springs to the system. As a result, the stiffness matrix can always have the inverse matrix and string shaped objects can be deformed stably and correctly. (author abst.) |
