CenterOn3()
  • Returns the center PntSol of the solution of index Index computed by this algorithm. ParArg is the parameter of the point PntSol on the third argument.

IsTheSame1()
  • Returns true if the solution of index Index and, respectively, the first or second argument of this algorithm are the same (i.e. there are 2 identical circles).

None* These constructors create one or more 2D circles of radius Radius either - tangential to the 2 curves Qualified1 and Qualified2, or - tangential to the curve Qualified1 and passing through the point Point, or - passing through two points Point1 and Point2. Tolerance is a tolerance criterion used by the algorithm to find a solution when, mathematically, the problem posed does not have a solution, but where there is numeric uncertainty attached to the arguments. For example, take two circles C1 and C2, such that C2 is inside C1, and almost tangential to C1. There is, in fact, no point of intersection between C1 and C2. You now want to find a circle of radius R (smaller than the radius of C2), which is tangential to C1 and C2, and inside these two circles: a pure mathematical resolution will not find a solution. This is where the tolerance criterion is used: the algorithm considers that C1 and C2 are tangential if the shortest distance between these two circles is less than or equal to Tolerance. Thus, a solution is found by the algorithm. Exceptions GccEnt_BadQualifier if a qualifier is inconsistent with the argument it qualifies (for example, enclosing for a line). Standard_NegativeValue if Radius is negative.

For example, take: - two circles C1 and C2, such that C2 is inside C1, and almost tangential to C1; there is in fact no point of intersection between C1 and C2; and - a circle C3 outside C1. You now want to find a circle which is tangential to C1, C2 and C3: a pure mathematical resolution will not find a solution. This is where the tolerance criterion is used: the algorithm considers that C1 and C2 are tangential if the shortest distance between these two circles is less than or equal to Tolerance. Thus, the algorithm finds a solution. Warning An iterative algorithm is used if Qualified1, Qualified2 or Qualified3 is more complex than a line or a circle. In such cases, the algorithm constructs only one solution. Exceptions GccEnt_BadQualifier if a qualifier is inconsistent with the argument it qualifies (for example, enclosing for a line).
