A New Algorithm of Boolean Operation in Three Dimensional Space

Zhu Feng Zeng Xianzhang He Yuanjun  
This paper presents a three dimensional solid modeling system inwhich the surfaces of objects are approximated by polygonal planes.A threedimensional object is describied by boundary representation.A new inters-ection algorithm is presented which translates the infinite intersection linesinto the finite intersection lines in three dimensional space.A new rebuild-ing topology algorithm is also presented that from one intersection point theface topology related to the intersection point is rebuilt.Therefore the boo-lean operation algorithm is simplified and unified.The operation speed isalso increased.
