Generation of free-form surface model by reversible rounding operation

   
   

A method of generating a free-form surface model includes the steps of applying linear transformation to a lattice polygon model to generate vertices of a free-form surface model corresponding to respective vertices of the lattice polygon model, and generating control points of cubic Bezier curves that connect the vertices of the free-form surface model, and that correspond to respective edges of the lattice polygon model.

Um método de gerar um modelo da superfície do livre-formulário inclui as etapas de aplicar a transformação linear a um modelo do polygon do lattice para gerar vertices de corresponder modelo da superfície do livre-formulário aos vertices respectivos do modelo do polygon do lattice, e de gerar pontos de controle das curvas cúbicas de Bezier que conectam os vertices do modelo da superfície do livre-formulário, e que correspondem às bordas respectivas do modelo do polygon do lattice.
