Technical Perspective: A 'Reasonable' Solution to Deformation Methods
Jacobson et al. construct a deformation method that allows a wide range of handle types (points, line segments, open and closed polygons) and produces deformations that are biharmonic functions.Bounded Biharmonic Weights For Real-Time Deformation
Changing an object's shape is a basic operation in computer graphics. Our goal is to make the design and control of deformations simpler by allowing the user to work freely with the most convenient combination of handle types …COLUMN: Last byte
