It is very interesting and important to develop a behavioral model of cracks, which produces realistic crack patterns, from not only a theoretical but a practical view, e.g., realistic image synthesis in CG.<\/jats:p><jats:p>In this paper, we first analyze the typical two crack patterns produced in different materials, one of which is only slightly sticky and the other is very sticky. We then show some basic assumptions useful for constructing a behavioral model of cracks.<\/jats:p><jats:p>Next, we present the behavioral model having one parameter of stickiness; and presenting several simulated crack patterns, we show that the constructed model is effective for visual simulation of crack patterns.<\/jats:p><jats:p>We then present CG images, synthesized by employing texture mapping techniques, of marble objects, china teacups, and a china vase, all of which have many cracks on their surfaces. Finally, we discuss further improvements for extending the model to one which works on any curved surface and produces more realistic crack patterns according to the shapes of the surfaces.<\/jats:p>","DOI":"10.1002\/scj.4690221109","type":"journal-article","created":{"date-parts":[[2007,7,7]],"date-time":"2007-07-07T20:03:41Z","timestamp":1183838621000},"page":"82-91","source":"Crossref","is-referenced-by-count":7,"title":["A behavioral model of cracks and its applications to cg"],"prefix":"10.1002","volume":"22","author":[{"given":"Norishige","family":"Chiba","sequence":"first","affiliation":[]},{"given":"Seiichi","family":"Wada","sequence":"additional","affiliation":[]},{"given":"Keimei","family":"Kaino","sequence":"additional","affiliation":[]},{"given":"Kazunobu","family":"Muraoka","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2007,3,21]]},"reference":[{"issue":"587","key":"e_1_2_1_2_2","first-page":"163","article-title":"The Phenomena of Rapture and Flow in Solid","volume":"221","author":"Griffith A.
