A Study of the Three-Dimensional Visualization of Soil Microstructure Based on MATLAB

At present, qualitative and quantitative analyses of the soil microstructure are mainly made on the two-dimensional level. The present study makes possible the three-dimensional visualization of soil microstructure by transforming the scanning electron microscopy (SEM) photographs into the three-dimensional digital map (DEM) with such abundant information as their inherent particles and apertures; it also makes available 2.560 as the fractal dimension for the DEM image of the sample soil by conducting a quantitative analysis of its microstructure with the projective covering method, a surface fractal measurement method.
