[postgis-devel] Polyhedral Containment

[Paul Ramsey]

Is there a 3d function that can answer this question and return true? (volumetric containment?)

ST_3dIntersects(
 'POLYHEDRALSURFACE( 
 ((0 0 0, 0 0 1, 0 1 1, 0 1 0, 0 0 0)),  
 ((0 0 0, 0 1 0, 1 1 0, 1 0 0, 0 0 0)), 
 ((0 0 0, 1 0 0, 1 0 1, 0 0 1, 0 0 0)), 
 ((1 1 0, 1 1 1, 1 0 1, 1 0 0, 1 1 0)),  
 ((0 1 0, 0 1 1, 1 1 1, 1 1 0, 0 1 0)),  
 ((0 0 1, 1 0 1, 1 1 1, 0 1 1, 0 0 1)) 
 )', 'POINT(0.5 0.5 0.5)');
