Geometric modeling deals with the mathematical representation of curves, surfaces, and solids necessary in the definition of complex physical or engineering objects. The associated field of computational geometry is concerned with the development, analysis, and computer implementation of algorithms encountered in geometric modeling. The objects we are concerned with in engineering range from the simple mechanical parts (machine elements) to complex sculptured objects such as ships, automobiles, airplanes, turbine and propeller blades, etc. Similarly, for the description of the physical environment we need to represent objects such as the ocean bottom as well as three-dimensional scalar or vector physical properties, such as salinity, temperature, velocities, chemical concentrations (possibly as a function of time as well).
