A method for facilitating a real-time shared viewing experience in a three-dimensional modeling environment, characterized in that the method comprises the steps of: receiving at a viewpoint controller engine of a centralized computing device a reservation indication indicating that a first computing device requests a reservation for control of a viewpoint modification of a three-dimensional model; storing at a data storage that is accessible to the centralized computing device, based on the reservation indication, an indication that the first computing device has the control of the viewpoint modification of the 3D model; preventing the second computing device from reserving the control of the viewpoint modification of the 3D model until a release indication is received, the release indication indicating that the first computing device releases the control of the viewpoint modification of the 3D model; receiving at the viewpoint controller engine a local viewpoint modification indication indicating that a viewpoint of a three-dimensional model has been locally modified at the first computing device, wherein, the 3D model corresponds to model data (62/62a) including component data corresponding to a plurality of respective components of the 3D model, and the component data including element data representing a plurality of respective sets of edges and faces corresponding to the plurality of respective components, and the viewpoint of the 3D model corresponds to a positioning of a rendering of the 3D model relative to a plane of a display device at the first computing device, the rendering based on the model data (62/62a); generating by the viewpoint controller engine, in response to the received local viewpoint modification indication, a viewpoint update indication descriptive of the modified viewpoint; and causing the viewpoint update indication to be transmitted to a second computing device, whereby the 3D model is rendered on a display device at the second computing device according to the modified viewpoint and the model data (62/62a), wherein causing the viewpoint update indication to be transmitted is performed based on the indication that the first computing device has the control of the viewpoint modification of the 3D model. receiving at a viewpoint controller engine of a centralized computing device a reservation indication indicating that a first computing device requests a reservation for control of a viewpoint modification of a three-dimensional model; storing at a data storage that is accessible to the centralized computing device, based on the reservation indication, an indication that the first computing device has the control of the viewpoint modification of the 3D model; preventing the second computing device from reserving the control of the viewpoint modification of the 3D model until a release indication is received, the release indication indicating that the first computing device releases the control of the viewpoint modification of the 3D model; receiving at the viewpoint controller engine a local viewpoint modification indication indicating that a viewpoint of a three-dimensional model has been locally modified at the first computing device, wherein, the 3D model corresponds to model data (62/62a) including component data corresponding to a plurality of respective components of the 3D model, and the component data including element data representing a plurality of respective sets of edges and faces corresponding to the plurality of respective components, and the viewpoint of the 3D model corresponds to a positioning of a rendering of the 3D model relative to a plane of a display device at the first computing device, the rendering based on the model data (62/62a); the 3D model corresponds to model data (62/62a) including component data corresponding to a plurality of respective components of the 3D model, and the component data including element data representing a plurality of respective sets of edges and faces corresponding to the plurality of respective components, and the viewpoint of the 3D model corresponds to a positioning of a rendering of the 3D model relative to a plane of a display device at the first computing device, the rendering based on the model data (62/62a); generating by the viewpoint controller engine, in response to the received local viewpoint modification indication, a viewpoint update indication descriptive of the modified viewpoint; and causing the viewpoint update indication to be transmitted to a second computing device, whereby the 3D model is rendered on a display device at the second computing device according to the modified viewpoint and the model data (62/62a), wherein causing the viewpoint update indication to be transmitted is performed based on the indication that the first computing device has the control of the viewpoint modification of the 3D model.
