We look at something focal point by focal point and remember them as we mentally construct a whole.
Wide scenes, either interior or exterior, are difficult to produce in two-point perspective, because of distortions that begin to appear outside of the foveal area William describes. Often, the solution to this is to add more vanishing points on the horizon to rectify the distortion of objects out from the center. This process attempts to recreate the new vanishing points that the view "creates" by panning his view to one side or other. Many artists take account of this phenomenon, and panoramic photos also show the multiplying of vanishing points. In fact, the computer virtual reality technique of making an apparently seamless panoramic view 360 degrees through the horizontal axis (and often vertically, too) relies on two aspects: (1) a wireframe-type grid of the sphere of viewing, and (2) a series of photographs taken along the vertical and horizontal axes (from a fixed position using a tripod). The VR program stitches the photos together, so that when the viewer uses a mouse to rotate the view, the separate images are displayed in what appears to be a continuous scan. The multiple vanishing points of each image meld unnoticed into the resulting VR view.
