Recursive intersection toolkit

GAIA Home Intersections in CAD Change of representation Intersection algorithms in GAIA Algebraic geometry for CAD Applications Software Toolkit approximate implicitization Recursive intersection toolkit Approximate implicitization by point sampling & estimated normals The GAIA project	Recursive intersection toolkit The toolkit combines recursive subdivision and approximate implicitization for identifying all branches of the intersection (within a user defined tolerance), as well as software for refining the intersection curves produced to the required accuracy. The toolkit offers: Intersection of a curve and a point Intersection of two NURBS curves Intersection of a NURBS curve and an implicit curve Intersection of a NURBS curve and a NURBS surface Intersection of a NURNS curve and an implicit surface Intersection ot two NURBS surfaces Intersection of a NURBS surface and an implicit surface Self-intersection of NURBS curve Self-intersection of NURBS surface The toolkit is currently a prototype, but the plan is to further test and stabilize to bring the toolkit to a sufficient quality level for industrial use.
