Islay 3D is another educational programming environment of which feature is an intuitively comprehensive user interface in terms of state transition diagrams. Unfortunately its animation definition was too memory-hungry when played by the built-in interpreter. In this paper, we present a translator of the animation definitions of Islay 3D into ActionScript3 (AS3). Compiling the AS3 codes by way of Papervision3D, we obtain the 3D Flash animation file playable on the Flash platform. It will be shown that the memory and CPU usages will be much saved, quartered and halved, respectively, by virtue of the translator.展开更多

Tourism offers and services should be complete, current, and qualitative through all phases of the planning process, starting from preparation to implementation. The modem tourist offer of services involves production of multivalorized natural, anthropogenic, communicative, and receptive values of a particular facility or geographic area as a tourist destination target. The tourist or client should experience complete ＂tour-retour＂, or as stated in the tourism ＂I came, saw, took, in order to come back again＂, through all the stages, from the preparation of the travel, the stay, up to the departure. Tourism, in the near future, or the tourist dialectical development in order to be completely realized, must pass through the so-called tourist triad from audiovisual or real, to virtual or imagined and to virtuous or perfect. In that case, an ecstasy of admiration, enhancement, prowess, joy, pleasure, excitement, success, and happiness will cause tourists to visit the place again. In order to experience the previously mentioned states, arrangement from professionals, tourist managers, and animators from various areas is of great importance.展开更多

Also, the position of the animation art has been promoted by the expression and extension of the drama art spirit and expression technique in the creation of film and television animations to be greatly improved. In this paper, the characteristics of the virtual technique in drama are briefly introduced, and also the influence of the virtual technique on the creation offihn and television animations is analyzed.展开更多

It is shown here the multimedia environment provides us a new and desirable approach to enhance the delivery and interactivity of medical linguistic course.展开更多
