Chemis3D

 A Java Applet for On-Line 3D Visualization of Molecular Models.



With the mouse
  • Rotate the model by left-click while dragging.
  • Zoom in/out by right-click and drag.
  • Translate by left-click and drag with CTRL Key down.
  • Rotate in the X^Y plane by left-click and drag with SHIFT Key down.
With the menubar
  • Change the model Display (ball, stick or ball-stick).
  • Add/remove Hydrogens.
  • Color the model by atoms, groups or chains.
  • Pick or Label atoms
  • Measure interatomic distances .
Note: with Netscape the Menubar get focus by a double click.
          with Internet Explorer 4.0, by default the Menubar is embedded in the applet.


Chemis3D use data files like MDL molfile (*.mol) or XYZ (*.xyz) for common molecules,
and Protein Data Bank files (*.pdb) for macromolecular structures.

Chemis3D is a small applet (33Ko) quickly loaded.
Its integration in a HTML code is very easy with full of options.
Required Optional
<APPLET CODE=Chemis3DApp.class ARCHIVE="Chemis3D.jar"
WIDTH=360 HEIGHT=360>
<PARAM NAME="model" VALUE="DNA3.txt">  // The data file.
<PARAM NAME="filetype" VALUE="x-pdb"> // Filetype format(x-xyz,x-mol or x-pdb)
<PARAM NAME="display" VALUE="ball">  // Display style(ball, stick, ball-stick)
<PARAM NAME="fastmove" VALUE="on">  // Wireframe on move (on/off)
<PARAM NAME="color" VALUE="atom">  // Color display (atom, group, chain)
<PARAM NAME="scale" VALUE="1.0">  // Scalefactor (0-3)
<PARAM NAME="light" VALUE="0">   // Light intensity (0-255)
<PARAM NAME="back" VALUE="#000000"> // Background Color(#hex) or Image(*.jpeg,*.gif)
<PARAM NAME="setmenu" VALUE="100,100,250"> // Menu position (x,y,width)
</APPLET>
Chemis3D is fully compatible with Netscape Navigator 3.01-4.5, Microsoft Internet Explorer 3.0-4.01 and HotJava 1.1.2.

Trick:
  • With the most recent versions of Netscape Navigator and HotJava you can use the ARCHIVE tag to allow download of all the Applet in a single compressed jar file (Chemis3D.jar #19Ko).
  • The filetype parameter enable the use of datafiles in text format (*.txt ) and avoid the use of a specific chemical S/MIME type on the host server.
