This work introduces a MATLAB code to perform the topology optimization of structures made of bars using the geometry projection method. Summary - Geometric Modeling • Geometric Modeling is a fundamental CAD technique. A drawback of pixel-oriented visualization techniques is that they cannot help us much in understanding the distribution of data in a multidimensional space. Used by permission of B. Wright, Visible Decisions Inc. Visualization of the data as perspective landscape, The data needs to be transformed into a (possibly artificial), 2D spatial representation which preserves the characteristics, n equidistant axes which are parallel to one of the, screen axes and correspond to the attributes, The axes are scaled to the [minimum, maximum]: range, Every data item corresponds to a polygonal line which, intersects each of the axes at the point which, corresponds to the value for the attribute, Visualization of the data values as features of, Shape coding: Use shape to represent certain, Color icons: Use color icons to encode more, Tile bars: Use small icons to represent the, relevant feature vectors in document retrieval.
