## 1. Introduction

KMovisto is a molecule viewer for using in quantum chemistry. You are able to import GAUSSIAN 94 and GAUSSIAN 98 files (obtained from UNIX or MS Windows systems) or XYZ files and view your results in several view modes or edit the molecule geometry. Especially the 3D view modes (anaglyph or stereo pair) make it possible to enjoy stereoscopic impressions of the molecular structure - so this is what KMovisto makes a real 3D molecule viewer.

With KMovisto you are also able to generate POV-Ray scene files of your molecules. POV-Ray is one of the most popular freeware ray tracing programs. You can download POV-Ray for various platforms and render your perfect molecule images for high quality presentations. Fig. 1 shows a sample image of a thiosulfinic acid derivate.

Further KMovisto generates VRML (Virtual Reality Modeling Language) files of your molecules. VRML is a simple way to provide 3D sceenes for the world wide web. To view VRML files you need an appropriate VRML browser like FreeWRL for Linux platforms or the Cosmo Player browser plug-in for MS Windows systems.

Since release 0.6.0 KMovisto provides a plugin interface for creating own file import and export libraries. See chapter 6 for further informations.
