Description
Summary:	Noise is used to create realistic animations that look like natural phenomena as well as procedural textures and shapes by adding randomness to graphical applications. In this paper, we suggest a method to edit noise values to satisfy the constraints that reflect the user's demands while maintaining the inherent statistical features of the noise function. Noise editing uses optimization to minimize the difference between the statistical characteristics of the ideal and edited versions of a noise source. Using our editing method, detailed control of animation and shape data that include noise is possible. Copyright © 2004 John Wiley & Sons, Ltd.
