Abstract: A method, system, and computer program product/computer readable storage medium provide the ability to render a shadow. A three-dimensional (3D) scene comprising an object is obtained. An external physical light source that is external to the 3D scene is detected by a sensor. An artificial light source is created in the 3D scene that corresponds to the external physical light source. Based on the artificial light source, a shadow of the object is cast. The 3D scene including the object and the shadow are then rendered.

Abstract: A method, apparatus, system, and computer program product provide the ability to display representative properties of a three-dimensional scene view. A 3D scene and a 3D representation of a coordinate system of the 3D scene are displayed. Different faces of the 3D representation represent and correspond to different viewpoints of the 3D scene. Different statistics for features of the 3D scene are reflected on the different faces of the 3D representation based on the viewpoint corresponding to each face. Manipulation of the 3D representation identifies and selects a different viewpoint of the 3D scene which is then reoriented accordingly.

Abstract: A method, apparatus, system, article of manufacture, and computer program product provide the ability to provide three-dimensional (3D) content. A user is authenticated and authorized to view the 3D content. The 3D content is displayed. A change in the user state is detected. Based on the user state change, two-dimensional (2D) content is displayed instead of the 3D content.

Abstract: A method, apparatus, and system provide the ability to interact with a virtual stereoscopic object. A set of sensors is placed adjacent to a stereoscopic viewing area. A stereoscopic object is projected in the stereoscopic viewing area. A user's body part is tracked using the set of sensors. A gesture of the user's body part is determined (based on the tracking). Based on the gesture, an interaction event is actively and dynamically applied to the stereoscopic object.
