In recent years, the contents using 3-dimensional computer graphics(3DCG) animation are spreading widely according to the rapid expansion of computers with an advanced graphics function.The visual information by 3DCG has an effect for understanding the rough contents.The contents which combined interpretational documents and 3DCG animation were created in this study.Furthermore,the function which displays a document by using a mouse also was presented.Thus,the contents which the users need only informations required were realized to aim at the user's request.The created contents are composed with 3DCG manuals of phase microscope "TPC-02" made by Taiyo-Elecs Company.With this manual, it was confirmed that the difficult information through the expressional 3DCG animation was found to be supplemented with the written form.The authors are also expecting that 3DCG contents which can present a document according to the operation of a user are effective as well as a manual of information technology related apparatus.

Moving objects colliding with one another, such as falling rubble in collapse phenomena, cause complicated motions. In order to effectively produce animations of such objects in computer graphics, a physically-based simulation method is usable and often used.Our aim is to develop a rigid body dynamics simulation method which is simple to understand and easy to implement.In this paper, we propose a method developed by implementing the penalty method that was realized in Particle-Element-Method by assigning Voigt model to both normal-direction and tangential-direction of a particle-sphere, so as to be suitable for three-dimensional polygonal models. Thus we can solve collision, contact, and frictional force in a uniform manner.

Making the “HAIKU” in English has been increased recently . In this case, the authors believe that the zest will come out when they compose “HAIKU” with the writing to brush touch as in Japanese lettering. So we developed the method to express the descriptive English letters in brush touched characters. And we made a trial to make the software which can connect letters between a character and characters with the spline curve to look them more naturally. We make it possible the curve between characters to change the lines width of a character, and expresses brushstroke, where the user can be to move it freely.

We have been researching and developing an A-V system to transmit information related with “arousal of deep admiration” in our mind. Up to now, we found three necessary conditions; (A) a dark and silent environment, (B) contents of image and sound which included the information related with arousal of deep admiration, (C) Extra HI System M which can reproduce the information related with arousal of deep admiration. However, it is difficult to realize above three conditions at a living environment. In this paper, we consider and propose a method to transmit information of arousal of deep admiration even in a living environment.

This paper realizes visualization of human body sensing for supporting sports motion analysis. In sports motion analysis such as hitting or throwing a ball, kinesiological information such as myoelectric potential values are checked corresponding to form actions in video images. To support this process, the kinesiological information is mapped onto a human body skeleton model and displayed with a variation of colors. The animation enables us to observe transition of the kinesiological information according to time spent during the actual action forms. This method is applied in practical use to golf swings and bowling, and its effectiveness to distinguish differences among players is sighted.

The main aim in this study is to represent imagined scenes, to be memorized by reflecting physiological and psychological characteristics of human vision systems. To this end, a new style ofnon-photorealistic rendering, termed imagined scenery rendering, has been investigated to produce cognitively-realistic scenes of beauty residing in human minds. In this paper, designated filters are proposed to generate representative perceptive deformation effects.

We study the educational contents using 3DCG. Important points of the education contents production are that it improves the intelligibility of the user and that the interest of the user continues. Then, the un-contacting viewer using CCD camera was built in this time, and the visual education contents was made. To begin with, the movement of the user head is taken in by CCD camera. Next, the movement of the head is recognized. Then, the movement of the object is linked. As this result, it became possible that bidirectionality was given as contents of the user participation type. And, the questionnaire was carried out, and then, the effectiveness of the system was confirmed.
