    Efforts to develop a more accurate model of the human spine and torso in order to improve realism in human motion modeling are discussed. The model of spinal motion, which is represented within Jack (a software system for human figure modeling and manipulation), is described. The impact parameters, vertebral joint movement, and the spine database are considered. Application of the motion model is ... View full abstract»

    An approach to boundary evaluation and a boundary representation are presented. The approach uses nonmanifold topology (NMT) to overcome editing and coverage limitations associated with the manifold nature of existing boundary evaluation schemes. It merges the input primitives into a single representation and selects the entities in the merged set that constitute the result of the Boolean operatio... View full abstract»

    An open approach to graphic arts and prepress information exchange called constructive page description (CPD) is described. An existing approach for the exchange of continuous tone picture and line art data between electronic prepress systems called the Digital Data Exchange Specification (DDES) is examined, and its deficiencies are revealed. The goals of the CPD approach and its basic concepts ar... View full abstract»
