ST_3DIntersects
Determines whether 3D models and 3D geometries intersect.
Syntax
bool ST_3DIntersects(meshgeom geom1, meshgeom geom2);
bool ST_3DIntersects(meshgeom geom1, box3d box);
bool ST_3DIntersects(sfmesh sfmeshObject1, sfmesh sfmeshObject2);Parameters
Parameter name | Description |
geom | Meshgeom object |
box | Specifies the box3d object. |
sfmeshObject | sfmesh object |
Description
This function checks whether two sfmesh objects intersect.
This function checks whether the sfmesh object intersects with the box3d object.
This function checks whether two meshgeom objects intersect.
If this function fails, NULL is returned.
Examples
select ST_3DIntersects(
'MESHGEOM(PATCH(TRIANGLESTRIP Z(0 0 0,0 10 0,0 0 10,0 10 10), POINT Z(0 0 0)))'::meshgeom,
'MESHGEOM(PATCH(LINESTRING(-1 0 0, -1 -0.5 0)))'::meshgeom);
