| 摘要 |
A method and apparatus for interactively generating and visually displaying deformed, free curved surfaces using a computer aided display apparatus by designating a desired deformation area, including an action point, on a non-deformed surface, determining a vector field function Fi (deformation rate) at each point within the deformation area; designating a deformation vector Vi* (deformation quantity and direction) at the action point; adding the position vector Pi-1* (non-deformed curved surface) to the position vector Vi* * Fi (deformation quantity) to generate a position vector Pi* (deformed curved surface); and visually displaying the deformed curved surface represented by the position vector Pi*.
