The 3D Molecular Viewer applet produces a three-dimensional view of a crystal structure that you can tilt and rotate by dragging with the momouse. If you are interested in specific atoms, you can use mouse to pick them up, then these atoms will be shown as bigger balls while other parts of this molecule will be drawn by stick model. Furthermore, you can draw a whole cell of a single crystal as well as multi-cells. The radius of the spheres is determined by the actual size of the specific atom.
Color is used to distinguish different atoms.
Show the relationship between moleculars which is important to chemistry study but ignored by other visualization tools. Show the relationship between cells including some important properties of crystal structure such as symmetry. Give viewer the impression of the whole crystal and inspire their thinking. Description and Features Double buffering implementation. If parts of the balls are overlaped, the parts further from viewers will be shaded by the parts nearer to the viewers.
