Project 15: Structure Viewer

Steffen Weber, July 1998


You should use Internet Explorer for this applet!
If your screen displays only 255 colors the quality will be very bad!

- Cu2FeSnS

about jAtom
Several other structure displaying applets are already available on the internet. jAtom is new in the sense that it does not need to be supplied with a input file containing cartesian atom coordinates. jAtom generates all atom positions from the data for the asymmetric unit cell which are embedded as parameters directly in the HTML page. All 230 space groups are supported (1.settings only). This applet is a stripped down version of my Java application JSV. I will continue working on both this applet and JSV. If you are not familiar with the concepts of the asymetric unit cell and space groups consult a book on crystallography or contact me by email.

problem !
Although this applet runs perfectly when I execute it with the JDK's appletviewer, it does not display the bonds correctly when running it in a browser (especially Netscape). The reason for this is still unknown to me. I will try to find a workaround.

applet error ?
If you get a status bar message like JSVapplet can't start after changing webpages you may try to click Reload.

explanations for how to create structures follow soon. Meanwhile you can just have a look at this page's source code in order to see how it is done.
