(e.g., Adobe Photoshop or similar). The individual items within the scene that are common
between scans are then linked/stitched together to form a mosaic.
2. With 3D data rendering, the same series of scene capture is placed in a mosaic format. The
difference between the 2D and 3D mosaic is that the 3D data is plotted into a 3D rendering software package (e.g., Leica Cyclone or similar) for the x/y/z point coordinates, thus producing a 3D “point cloud” of individual echoes (see Figure 23.8 in Chapter 23). This is particularly useful for modeling of in situ structures based upon real data for metrology purposes.
