Misleading documentation regarding specification of BoundingBox coordinates
Documentation regarding BoundingBox says:
BoundingBox { expression, expression, expression, expression, expression, expression }; Forces the bounding box of the scene to the given expressions (X min, X max, Y min, Y max, Z min, Z max).
whereas usage of In BoundingBox requires [xmin,ymin,zmin,xmax,ymax,zmax] (instead of [xmin,xmax,ymin,ymax,zmin,zmax]). See example in attached geo file InBoundingBox.geo
