Name

CG_3DIntersects — Tests if two 3D geometries intersect

Synopsis

boolean CG_3DIntersects( geometry geomA , geometry geomB );

Description

Tests if two 3D geometries intersect. 3D geometries intersect if they have any point in common in the three-dimensional space.

Performed by the SFCGAL module

[Note]

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).

Geometry Examples
