Free form volumes in rational Bézier representation are defined via homogeneous coordinates and two applications are pointed out : generation of solid primitives and curve and surface modelling by the way of volume deformation. Visualization techniques are reviewed, too.
Free form volumes in rational Bézier representation are derived via homogeneous coordinates. Some properties and constructions are presented and two applications of free form volumes are discussed: definition ot solid primitives and curve and surface modelling by the way of volume deformation.
