Title:
仮想3次元空間内の可視的コンテントを表示する方法とシステム
Document Type and Number:
Japanese Patent JP4722379
Kind Code:
B2
Abstract:
A system and system for positioning content elements in a virtual 3D space. A 2D base plane is designated in the 3D space with at least one page being parallel to the base plane. A viewpoint and viewing ray are selected in the 3D space from which to vie the 3D space with the viewing ray being neither parallel or perpendicular to the base plane. A 2D surfac 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 determind by the viewing ray. The process may be repeated as desired each time optionlly selecting a new viewpoint and/or selecting a new viwing 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.
