Improvement of free-form surfaces for product styling applications

摘要

There are a number of ways of describing free-form surfaces within geometric modelling systems. For product styling and related activities, there is a need to ensure that surface quality is good and that patches join together smoothly. Additional parameters can be introduced to allow surfaces to be modified. This raises the question of whether these can be chosen automatically, and this in turn requires measures of what is a 'fair' surface. Measures based on surface curvature are discussed and applied to adjust surface patches presented in terms of point meshes.
