1. A method for dynamic sensor placement comprising:

  • positioning at least one sensory device in a scene of a 3D site model supported in a computer;

    said 3D site model including data defining a plurality of surfaces in three dimensions making up a plurality of objects in the site model;

    rendering in said computer an image of at least part of said scene of the 3D site model in which at least part of a coverage of said at least one sensory device within the scene of said 3D site model is displayed, and part of the scene of the 3D site model outside said coverage is displayed, said coverage being derived in accordance with sensor parameters associated with said at least one sensory device; and

    said rendering of said image being derived for a view point in said 3D site model that is different from the positioning of said sensory device; and

    wherein said rendering step renders the coverage of said sensor in accordance with said sensor parameters such that surfaces in the 3D site model in said image have a texture that differentiates the coverage from the part of the scene that is not in said coverage;

    said surfaces in said image being disposed in the site model at a plurality of different respective three dimensional orientations; and

    wherein, when one of the surfaces or objects of the 3D site model is positioned so as to be an occlusion between an occluded area that absent the occlusion is in the coverage covered by said at least one sensory device, said image is rendered so that the occluded area has a texture that differentiates from surfaces in the coverage of the sensory device.
