1. A method implemented by a programmed computer, for displaying a projection of a virtual three-dimensional (3D) space via a display device, comprising:
- a) designating a 2D base plane in the virtual 3D space;
b) positioning a first page and at least a second page or a content element in the 3D space with at least the first page parallel to the base plane, wherein each page is a 2D array of 2D and/or volumetric 3D content elements and each page has a layout;
c) selecting a single viewpoint and a viewing ray extending from the viewpoint and intersecting the base plane at an angle between 0 and 90°
;
d) positioning a first planar 2D surface in the 3D space at a predetermined distance from the viewpoint, so that the first planar 2D surface intersects the viewing ray between the viewpoint and the base plane so as to define a viewing frustum, within which is a viewing space, wherein the viewing space contains at least a portion of the first page and at least a portion of the second page or content element;
e) projecting the entire viewing space onto the first planar 2D surface using a single perspective projection determined by the viewing ray, such that for every point in the viewing space that is projected onto a corresponding point on the first 2D surface, that point of the viewing space, the corresponding point projected onto the first 2D surface, and the viewpoint are collinear;
f) optionally projecting the single perspective projection on the first 2D surface onto a second 2D surface; and
g) displaying the first 2D planar surface or the second 2D surface via a display device.

Abstract
A system and system for positioning content elements in a virtual 3D space. A 2D base plane is designated in the 3D space, and the visual content is positioned in the 3D space with at least one page being parallel to the base plane. A viewpoint and a viewing ray are selected in the 3D space from which to view the 3D space with the viewing ray being neither parallel nor perpendicular to the base plane. A 2D surface is then positioned in the 3D space so that the 2D surface intersects the view ray between the viewpoint and the base plane. At least a portion of the 3D space is then projected onto the 2D surface by a perspective projection determined by the viewing ray. The process may be repeated as desired each time optionally selecting a new viewpoint and/or selecting a new viewing ray and/or altering a property of one or more content elements. The projection onto the viewing surface may be displayed on a display device such as a computer monitor.
