Method and apparatus for computating deformation of deformable objects in real time

According to an embodiment, a method and apparatus for computing a deformation amount of a deformable object in real time are provided. The method comprises: deriving a primary parameter used to compute an amount of deformation in real time by computing necessary deformation information through a shape mode of a deformable object, prior to computing the amount of deformation in real time; and obtaining the amount of deformation of the deformable object in real time using the primary parameter.
