Can threejs realize scene as this link described?

I have found let transparent objects with depthTest & depthWrite enabled may help for only draw the top most transparent object, but a black quad may display, due to underlying objects be discard.

Is it possible to render transparent objects with z-buffer enabled to a “transparent layer” first, then draw the result “transparent layer” with opaque object to got the expecting effect?
