Design Automation of Human-Centered Products

This chapter presents the techniques for transforming the free-form shape of a product worn by a human body to shapes that ‘fit’ other human bodies. The design automation techniques introduced in this chapter focus on how to retain the spatial relationship between the designed product and the digital human body. Four techniques are introduced, which include direct transformation of style design, shape warping based on free-form deformation (FFD), volumetric parameterization based on spatial deformation, and flexible shape control in design transformation. All these techniques require that input human bodies are represented by piecewise linear surfaces with a consistent mesh connectivity as the input.
