A method of using a computer graphic system for free-form deformation of geometric models. The method is based on the use of a control-point grid which is imposed on the model and which can then be moved by a system designer to specify a deformation to a particular region of the model. Displacement of...http://www.google.fr/patents/US4821214?utm_source=gb-gplus-shareBrevet US4821214 - Computer graphics method for changing the shape of a geometric model using free-form deformation
