Abstract
Official abstract text for this publication.
A method and system for approximating a curve, and a graphic display control method and apparatus are disclosed. The method for approximating a curve comprises the steps of acquiring number information of subdividing points for subdividing a curve needed to be approximated based on coordinate information of control points of the curve, acquiring coordinate information of the subdividing points based on the number information of the subdividing points and the coordinate information of the control points, and connecting the subdividing points with straight lines based on the coordinate information of the subdividing points. The invention could achieve efficient curve approximation and in turn achieve efficient graphic-display control.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for approximating a curve implemented on an apparatus comprising a subdivision module and a coordination calculation module, the subdivision module and the coordination calculation module including at least one processor, the method comprising: acquiring, via a subdivision module, number information of subdividing points for subdividing a curve needed to be approximated based on coordinate information of control points of the curve; acquiring, via…
