| Abstract: | The principles and methods of realizing wavelet multiresolution representation of uniform cubic B-spline curves and surfaces were introduced. For region of interest and background region a method was proposed, which is used to represent the uniform B-spline surfaces by different resolution. The practical example shows that the display speed of surfaces can be greatly improved by this method and it is extremely useful for storage or multiresolution editing of surfaces. |
