| Research Abstract |
For several years, we are trying to apply effectivaly computer graphics to education of fluid mechanics, hydraulics, coastal engineering and hydrology. Merits of computer graphics compared with conventional education tools such as (i) bloak board, (ii) OHP, (iii) movie, video or TV may be mentioned, among other, as (i) Graphs and figures are displayed clearly and precisely by colour, consequently with stronger impression to students. (ii) Theoretical results can be shown exaggerating the differences by freely changing the vertical and horizontal scale ratio of (This cannot be done on video, movie and TV. (iii) Theoretical results expressed by mathematic formulae can be expressed by graphs for an arbitrary condition. (iv) Time dependent phenomena can be shown by animation-like presentation. (v) Students can understand more the theories through programming by themselves. (vi) Reproduction of products, i.e, copy of floppy disks, is easy and cheap. Following programs are completed.
