Chemis3D, Molecular Viewer Applet

Chemis3D is a Java Applet which renders virtual 3D molecular models within a Web document. It is specially designed for open interactive molecular visualization on the Internet or via an intranet. Molecular structures can be manipulated in real-time and rendered in various styles and appearances.

Chemis3D is a small applet (~30Ko) running well on any Java-enabled browser and requiring no specialized plug-in nor professional applications.



Main Features  

  • Real-time manipulation and fast 3D rendering.

  • Wide variety of molecular representations including special styles and color coding schemes for proteins and nucleic acids .

  • Enhanced interface using popumenu and key shortcuts .

  • Multi-models display and molecular animation capabilities.

  • Measuring and analysing tools.

  • Support of the most popular molecular data formats :
    • Brookhaven Protein DataBank (*.pdb).
    • MSC XMol files (*.xyz).
    • MDL molfiles (*.mol).

  • Zip and GZIP chemical datafiles support.

  • Simple integration and easy customization in a web page.

  • Javascript-Java and inter-Applet communication support.



No Java 2 SDK, Standard Edition v 1.4 support for APPLET!!

Quick Start

With Mouse, Popup Menu or Key Shortcuts,

  • the model can be viewed as balls, sticks, ball&stick, wireframe, and backbone (proteins and nucleics).

  • the model can be colorized according to atoms nature (CPK Element), appartenance (residue, shapely, chain) and position (group, temperature).

  • the model can be rotated in 3D, rotated in plane, translated or zoomed.

  • the model can be autorotated or animated (multi-models file).

  • atoms or groups can be identified, labeled and highlighted.

  • distances, angles and torsions can be easily measured.
