Hi Felix, This was fixed in PostGIS 2.5. There your query ends up with geometry like this: GEOMETRYCOLLECTION Z (TIN Z (((0 0 0,0 1 0,1 1 0,0 0 0)),((1 0 0,0 0 0,1 1 0,1 0 0)),((0 1 1,1 0 1,1 1 1,0 1 1)),((0 1 1,0 0 1,1 0 1,0 1 1)),((0 0 0,0 0 1,0 1 1,0 0 0)),((0 1 0,0 0 0,0 1 1,0 1 0)),((1 0 1,1 1 0,1 1 1,1 0 1)),((1 0 1,1 0 0,1 1 0,1 0 1)),((0 0 1,1 0 0,1 0 1,0 0 1)),( (0 0 1,0 0 0,1 0 0,0 0 1)),((0 1 0,0 1 1,1 1 1,0 1 0)),((1 1 0,0 1 0,1 1 1,1 1 0)))) ср, 18 июл. 2018 г. в 11:21, Felix Kunde <[email protected][mailto:[email protected]]>:Hi, thought that's easy to do with the postgis_sfcgal extension, but no: SELECT ST_Tesselate('BOX3D(0 0 0,1 1 1)'::box3d::geometry)); ERROR: Solid is invalid : PolyhedralSurface (shell) 0 is invalid: not connected : SOLID((((0/1 0/1 0/1,0/1 1/1 0/1,1/1 1/1 0/1,1/1 0/1 0/1,0/1 0/1 0/1)),((0/1 0/1 1/1,0/1 1/1 1/1,1/1 1/1 1/1,1/1 0/1 1/1,0/1 0/1 1/1)),((0/1 0/1 0/1,0/1 1/1 0/1,0/1 1/1 1/1,0/1 0/1 SQL Status:XX000 The polygons are not in the right order :-/ Also tried dumping and delaunay triangulation but yet not solution.

Is there a way in PostGIS to do this without specifiying each triangle and vertex for the new TINs explicitly? Idealy, I would just be able to issue a simple update statement without needing to think about vertex order and triangle order.
