Regularized Boolean Operations • Recall that Geometric/PARAMETRIC Modeling of Solid Modeling of Represent Curves Surfaces (Patches) ation, Differentia Perception Differentia l of Solids l Geometry Topology Ferguson Tensor and Solids Segments Product Solid Modeling 1 -2 Transform Bezier Segments 1 -2 Boundary Interpolati ng B-spline curves 1 -5 Composite NURBS ations and Projection s 1 -2 – the interior I(V) of a solid comprises all points within the solid and not those on its boundary – A point Q is exterior to the solid if there exists an open ball B of radius r centered at Q such that the ball does not intersect with the solid – A set of all exterior points is termed the exterior of the solid represented as E(V)

That is, C(V) = I(V) b(V) or I(V) + b(V) – Alternatively, the closure of a solid is the complement E(V) of its exterior
