6. 3-D data visualization. Download 'aperture_ data.txt' text file from Canvas. This file contains the CT data for a given core sample with a fracture. The core is 51.2 x 51.2 128mm3. In each of the x and y direction, the image of the core is divided into 256 grids and each grid has a length of 200". In each of the 256 256 pixels, the z coordinate of the top and bottom of the fracture is measured. The aperture (the local width of the fracture) is also known. The data file lists the above information in the following format (5 columns and N rows). Notice the x and y indices start at zero. x index y index z.upper z_lower aperture mn (a) First execute the following command: >> disp ('Problem #6: 3-D visualization'); (b) Open the text files, and read the data. Arrange the data and store in a N-by-5 matrix named data all. Notes: There are two strategies to read in the data file with fscanf. One is read, reshape, and transpose the data. The other is using format control in fscanf (c) Using the function surf, plot the upper and lower faces of the fracture in the same figure. Execute the following commands after you plot the faces. % remove the black lines, h1 and h2 are the handles to the two surfs set (h1,'linestyle', 'none); set (h2, 'linestyle', 'none'); % adjust view point view(3); % add axis label xlabel('x'); ylabel ('y'); zlabel ('z'); % colorbar colorbar; 6. 3-D data visualization.
