DS Visualizer

From MarcsHomepage


DS (Discovery Studio) Visualizer is a cut-down version of a commercial viewer/editor-program sold by Accelrys. DS Viewer comes as a Windows or Linux binary and the Windows version can also be downloaded as an ActiveX control usable for integration into other programs.

To download the binary you have to register at the Accelrys Website.

User Interface


DS Visualizer is a Windows app, which has been ported to Linux, it´s interface sticks to the Microsoft Style guide, and it makes extensive use of right-button-menu´s and quickhelp.

Contrary to the older WebLab Viewer, DS Visualizer has a pane-and-tab interface with an explorer like tree view on the left side and a graphics window on the right side. The tree view can be used to browse projects and directories and history of opened documents. It is also possible to activate further panes which -like in WebLab Viewer- allow browsing of a tree representation of the loaded structure and to show a data table with further annotations, which is a very usefull feature of the program.
