- a curve and a surface, - a curve and a surface,
- two surfaces. - 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 ### 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 *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.
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. These classes use Euclidean distance as the criteria for optimization.
### Extrema between Curve and Surface ### 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 ### 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.
