Shape design and modeling with 1/f fluctuation characteristics

Abstract

This chapter first describes the extraction and analysis of 1/f fluctuation characteristics involved in the shape of ceramics. The surface topography of various teacups is measured using X-ray CT or laser metrology, and the wave patterns are then analyzed using the FFT method to clarify power spectrum-spatial frequency characteristics. Next, a couple of methods for shape design that utilize the power spectrum characteristics are explained. Finally, the modelling of aesthetically pleasing objects is demonstrated using the rapid prototyping method. © 2011 Springer-Verlag London Limited.
