Line of sight (sometimes written line-of-sight or abbreviated to LoS) is an invisible straight line used to determine whether entities can see other entities in the world. (If the line of sight is unobstructed from a viewer to a target, it is "established", and the game decides that the viewer can see the target.)
NPCs can only establish line of sight within their viewcone, in turn established by the width of their field of view, in turn established by the value of their m_flFieldOfView.
LOS is blocked by all Solid geometry (Models, func_detail brushes, etc.) unless the brush/model is has a SolidMask that is NotSolid to LOS, ie Transparent.
The Block LOS tool texture is specifically designed to block LOS.
