I am trying to develop a visual aid for a scientist friend working with micro- structures. His problem is that he wants to see the behavior of a crack going through a cut-plane of a volume with uniformly distributed but randomly oriented objects of fixed shape and size. Let's say that the objects in the volume are cylinders for the sake of discussion. By making a random cut in the plane, I should be able to come up with a plane that if looked from the top one could see different sizes of ellipses, circles or rectangles. I have been looking at the problem in a object-oriented manner where every object, in this case cylinder, behaves independently from the others. So if I can come up with a cylinder that I can freely orientate, cut randomly and reorientate again to see the cut from the top, I think it is possible to do the same with many cylinders at the same time. My problem is that I don't know how to make this kind of 3D object that remembers its properties, ie. orientation, shape, cut-surface, etc. Is there any of you out there with brilliant ideas? Or is there any stack to work with 3D that I could obtain or buy? Any comments or suggestions will be much appreciated? -- Yuri Adrian Tijerino (Ph.D student) The Institute of Scientific and Industrial Research (SANKEN), Mizoguchi Lab, MULTIS project, Osaka University 8-1 Mihogaoka, Ibaraki-shi Osaka-fu, Japan 567 Tel: 06-876-2905 / Fax: 06-877-4977 email: yuri@ei.sanken.osaka-u.ac.jp

While this is not Hypercard, I have been doing animations of Molecular Dynamic simulation results using Mathematica on the Macintosh. The advantage of this is that one can use a mathematica formulation to set-up the problem and then have Mathematica generate the (PostScript) animation. One can also use color (nice for complicated situations). Dr. Paul Fons Institute of Applied Physics Tsukuba University Tsukuba-shi, Ibaraki-ken paul@bk.tsukuba.ac.jp --
