Abstract
A solid modeling technique is proposed which combines some essential
ideas from Constructive Solid Geometry and Implicit Surface Modeling
based on soft objects. The result is a surface definition (to be
called Boolean Compound Soft Object, or BCSO for short)
which consists of a boolean expression with union, intersection and set
difference operators. The geometric primitives that form the operands are
soft objects bounded by the iso-surfaces resulting from suitable
potential fields. These potential fields are parameterized by configurations
of so called skeletal elements. The resulting system, unlike most
CSG systems, combines blended and unblended primitives. An algorithm
for the boundary of a BCSO is presented which produces a mesh of triangles
to facilitate fast viewing and rendering.
