Abstract

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.

Claims

receiving real time positional information comprising geographic coordinate information and orientation information;

rendering a pseudo-realistic image of said loaded 3D scene responsive to said real time positional information;

providing an offset to said received real time positional information, wherein said offset is provided responsive to said building information model data, said rendering responsive to said provided offset and said received real time positional information;

displaying said rendered pseudo-realistic image; and

simultaneously displaying engineering information of said building information model data, said displayed engineering information being responsive to said real time positional information.

2. A non-transitory computer-readable medium containing instructions for controlling an electronic device to perform a method of on-site visualization of building information model data, the method comprising:
