Patent number: 8427473Abstract: An electronically implemented method of on-site visualization of building information model data, the method constituted of: loading a 3D scene comprising building information model data; receiving real time positional information comprising geographic coordinate information and orientation information; rendering a pseudo-realistic image of the loaded 3D scene responsive to the real time positional information; and displaying the rendered pseudo-realistic image. Preferably the method further provides for displaying engineering information of the building information model responsive to the real time positional information. Preferably, the pseudo-realistic image provides shadowing responsive to real time chronographic information and the received real time positional information.Type: GrantFiled: September 12, 2009Date of Patent: April 23, 2013Assignee: RDV Systems Ltd.Inventors: Nathan Elsberg, Alex Hazanov, Arkady Ratnitsky

Patent number: 8031210Abstract: A method of rendering a computer generated 3D scene integrated with a base image, the method comprising loading a base image, such as a photograph, and a computer generated 3D scene or model. The base image is displayed on a monitor, and in one embodiment the calibration of the camera which generated the base image is determined. The 3D model is rendered as an overlay of the base image responsive thereto. In another embodiment, the camera calibration of the 3D scene is made consonant with the base image by selecting corresponding points. The base image is then additionally displayed at a predetermined transparency as an overlay of the 3D model. A user then selects pixels of the base image overlay for placement in the foreground. The selected pixels are then displayed without transparency and the balance of the base image overlay removed rendering the integrated image.Type: GrantFiled: September 30, 2007Date of Patent: October 4, 2011Assignee: RDV Systems Ltd.Inventors: Nathan Elsberg, Alex Hazanov
