Concept Walk by Takashi Iba

In the afternoon, the rest of members in my laboratory arrived at Los Angeles. Then, we went to prepare the poster session for SIGGRAPH2008. SIGGRAPH2008 is held at Los Angeles Convention Center. It's a very very large building. We went to the center, and prepare the poster session. We put the following posters at the area "G250" and "G255".




- Kazeto Shimonishi, Junya Hirose, and Takashi Iba, "The Footprints of Chaos: A Novel Method and Demonstration for Generating Various Patterns from Chaos", The 35th International Conference and Exhibition on Computer Graphics and Interactive Techniques (SIGGRAPH2008), Los Angeles, USA, August 2008

In this poster, we propose a new method for generating various patterns from chaos, which visualize the history by converting the value into an angle and plotting the circle on the two-dimensional plane. As you know, "chaos" is one of the dynamical phenomena, which the behavior seems irregular but acts under a deterministic rule. Interestingly, the behavior of chaos is not only irregular, but also have a complex structure in the system. We show the map and movie to demonstrate that the proposed method is able to generates a lot of .. an infinite of various patterns according to the initial values and a control parameter.


Takashi Iba, Junya Hirose, and Kazeto Shimonishi, "ChaoSwitch: Toward Experiential and Reflective Learning of Complex Phenomena in 3D Virtual World", poster, The 35th International Conference and Exhibition on Computer Graphics and Interactive Techniques (SIGGRAPH2008), Los Angeles, USA, August 2008

In his poster, we propose a new experimental tool, which we call "ChaoSwitch", for learning complex phenomena of "chaos", which it is difficult to understand intuitively because of their complex behaviors. In our approach, the students learn the complex phenomena not only by listening teacher's lecture, but also by simulating the models in 3D virtual world. We have implemented "ChaoSwitch" in the metaverse of "Second Life", which is a 3D virtual world provided by Linden Lab. When you touch the box of "ChaoSwitch"in the metaverse, the box generates the Lorenz attractor above the box. Thus you can observe the trajectory from every point of view where you want.
