The sunlight itself will only affect the room in some parts, that is only the floor and walls as the sun is a directional light and it will not scatter around like the skylight, with exception to its indirect illumination from floor or wall.

• 阳光本身只会影响到房间的个别部分，比如阳光直射的地板和墙面，它不会象天光一样四处折射，除了地板和墙面产生的间接光照。
