The main aim of CIFmol is optimizing load speed and accommodating numerous views on a page (see the search tool below, which can retrieve multiple CIFs and render the structures therein reasonably quickly).
CIFmol started life as a CIF extension to GLmol, which provided much of the 'know how' and a framework on which to build a 3D CIF molecular view using the 2D HTML canvas.
Jmol also provided much inspiration. Indeed, one of the design prerequisites for CIFmol was that it could function as a front-end for Jmol, giving the user a quick view of a CIF structure before they give up because the Java applet is blocked or their mobile is struggling... (though this is no longer such an issue with the latest versions of Jmol).
CIFmol is currently under development and is copyright S. P. Westrip. Currently all rights are reserved, but the software will be made available under an open-source licence once it is good enough for public consumption ;-)
