Where is the 3d curve intersection algorithm? The OCCT version is 7.5.0

There is a couple of ways to find 3d curve intersection base on the input geometry (Geom to TopoDS_Shape).
Have a look at the documentation "occt_modeling_algos.pdf" for more details.
Also in 3D extrema algorithms are use to find intersection, look at GeomAPI_ExtremaCurveCurve and BRepExtrema_ExtCC.
