This topic describes the ST_Intersection function. This function returns the intersection of a scene object and a meshgeom object.


scene ST_Intersection(scene sc, meshgeom geom);


Parameter Description
sc The scene object.
geom The meshgeom object.


If you use a closed meshgeom object to clip a scene object, a part of the scene object remains inside the meshgeom object.

  • If the meshgeom object is not closed, NULL is returned.
  • If the meshgeom object is empty, NULL is returned.
