set (view.architectural="true");
set(view.architectural, true);
*smile*
EDIT: OOPS!~
set(view.architectural, 1.0);
you can set it anywhere from 0.0 - 1.0 to adjust the effect.
option to set
set(view.architecturalonlymiddle, true);
that applies the straight lines mostly in the middle and allows for some distotrtion at the tops and bottoms.
