This last picture is showing a structural ridge this allows you to eliminate collar ties to have a more open space. They transfer all of the load of the roof, both live ( snow ) and dead load to the outside walls where the weight is transferred down the walls to the foundation.
Typically this is done with large built-up post hidden in the walls not by windows.
