Using modal analysis, we compute the typical deformation modes of the shape. Modal analysis uses spectral analysis of the Hessian of a deformation en- ergy to find the shape's eigenmodes, which form a basis for the space of possible deformations.
Mar 27, 2009 · Using modal analysis, we are able to identify parts of the shape that tend to move rigidly. We define a deformation energy on the shape, ...
Modal analysis methods can simulate deformations by defining a deformation energy, and can be used for many purposes such as segmenting a shape into parts [22] ...
