- a curve and a surface,
- two surfaces.
### Extrema between Point and Curve / Surface
The *GeomAPI_ProjectPointOnCurve* class allows calculation of all extrema between a point and a curve. Extrema are the lengths of the segments orthogonal to the curve.
The *GeomAPI_ProjectPointOnSurface* class allows calculation of all extrema between a point and a surface. Extrema are the lengths of the segments orthogonal to the surface.
These classes use the "Projection" criteria for optimization.
### Extrema between Curves
The *Geom2dAPI_ExtremaCurveCurve* class allows calculation of all extrema between two 2D geometric curves. Extrema are the lengths of the segments orthogonal to two curves.
The *GeomAPI_ExtremaCurveCurve* class allows calculation of all extrema between two 3D geometric curves. Extrema are the lengths of the segments orthogonal to two curves.
The *Geom2dAPI_ExtremaCurveCurve* class allows calculation of all minimal distances between two 2D geometric curves.
The *GeomAPI_ExtremaCurveCurve* class allows calculation of all minimal distances two 3D geometric curves.
These classes use Euclidean distance as the criteria for optimization.
### Extrema between Curve and Surface
The *GeomAPI_ExtremaCurveSurface* class allows calculation of all extrema between a 3D curve and a surface. Extrema are the lengths of the segments orthogonal to the curve and the surface.
The *GeomAPI_ExtremaCurveSurface* class allows calculation of one extrema between a 3D curve and a surface. Extrema are the lengths of the segments orthogonal to the curve and the surface.
This class use the "Projection" criteria for optimization.
### Extrema between Surfaces
The *GeomAPI_ExtremaSurfaceSurface* class allows calculation of all extrema between two surfaces. Extrema are the lengths of the segments orthogonal to two surfaces.
The *GeomAPI_ExtremaSurfaceSurface* class allows calculation of one minimal and one maximal distance between two surfaces.
This class use Euclidean distance to compute minimum and "Projection" criteria to compute maximum.
