The deferred class GccInt_Bisec is the root class for elementary bisecting loci between two simple geometric objects (i.e. circles, lines or points). Bisecting loci between two geometric objects are such that each of their points is at the same distance from the two geometric objects. It is typically a curve, such as a line, circle or conic. Generally there is more than one elementary object which is the solution to a bisecting loci problem: each solution is described with one elementary bisecting locus. For example, the bisectors of two secant straight lines are two perpendicular straight lines. The GccInt package provides concrete implementations of the following elementary derived bisecting loci: More...

Detailed Description
The deferred class GccInt_Bisec is the root class for elementary bisecting loci between two simple geometric objects (i.e. circles, lines or points). Bisecting loci between two geometric objects are such that each of their points is at the same distance from the two geometric objects. It is typically a curve, such as a line, circle or conic. Generally there is more than one elementary object which is the solution to a bisecting loci problem: each solution is described with one elementary bisecting locus. For example, the bisectors of two secant straight lines are two perpendicular straight lines. The GccInt package provides concrete implementations of the following elementary derived bisecting loci:
- lines, circles, ellipses, hyperbolas and parabolas, and
- points (not used in this context). The GccAna package provides numerous algorithms for computing the bisecting loci between circles, lines or points, whose solutions are these types of elementary bisecting locus.
