Description

Returns true if two geometries intersect. Geometries intersect if they have any point in common.

Performed by the SFCGAL module

	NOTE: this is the "allowable" version that returns a boolean, not an integer.

Availability: 3.5.0

This method needs SFCGAL backend.

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