Computes the minimum distance between two geometries.

Performed by the SFCGAL module

NOTE: this function returns a double precision value representing the distance. |

Availability: 3.5.0

This method needs SFCGAL backend.

This function supports Triangles and Triangulated Irregular Network Surfaces (TIN).
