The first time our group take a brief look at the scilab, we are all intersted in it's graphic windows. It gives the user a direct and concrete impression about the abstract mathmatical datas and functions. But we also feel regret that the graphic windows can only export 2d files such as gif, jpeg..., no matter the graph we plot is 2d or 3d. And one day someone suggested we export out a real 3D graph, which can be seem form any aspect, zoom and unzoom, with rotation and various other attributes, just like playing a 3d game . Our crew considered it a science fiction at first, vrml changed our mind and finally gave birth to our VRscilab toolbox. For us, a group of undergraduate students with not much help, to design and write a complicated link closly with computer graphic theory programe is really a science fiction. VRML helps us, it is an well developped and popular opensource protocol with so pretty and simple syntax. Everyone can learn it in an hour and design his own graphic. And What's more, the way it define the point, point index ,color and color index is so familiared with the scilab plot function. They are all defined in several constant "block", and each shape can not only be defined separatly and join together easily but also be given a general enviroment attributes such as light color,intensity , background pic, etc. This is especially convinent for us, cause we can pay not so much attention to the string process detail and focus on the data process algorithm.
After that, everything goes well, we study the scilab plot function carefullly and worked out all the matrix convertion algorithm, although the time is not enough and we can't support all the functions...And we choose Tcl/Tk to write our interface and deal with the string processing and file writing. Tcl/Tk is a wonderful script language. There was also a interpreter embeded into the Scilab. Students in our group last year have designed EasyScilab by tcl/tk. Its powerful string manipulation fits greatly to VRscilab.
We not only want to just show Scilab group our work, but also make all the scilab fans easy to publish their work, for the vrml files generated by VRsiclab can be took everywhere. You don't need Scilab installed to show your graph, the true 3d graph can be embeded in any html files. That means you can show them on your homepage, send in E-mail to your friends ,everywhere on internet... ,concrete and intersting. And we also want to show why the tcl/tk a wonderful language with great future and how pretty interface it can make.
We wish our work can make Scilab more intersting, useful and popular.
