"Annexes append existing walls, or corners, opening up additional rooms where conventional annexes could not. These architectural forced perspective reliefs differ from the portals in that they do not represent a (nearly) 360° angle of vision (as with a fisheye lens) and so do not represent a (nearly) complete visual field. Annexes are based on a simple point-of-view idea, without the angle-of-view idea central to the portals. This point-of-view logic informs the specific idiosyncrasies of the tesseract as well: The ceiling and hence the imagined horizon line are on a significant tilt, and the top view of the gallery is not square (see drawing). Architecturally speaking, both plan and section contain tilted planes, coordinated to work together to form an integrated whole." - Andrew Kreps Gallery
