Der XNavigator

With the XNavigator you can immerse into the virtual city model of Heidelberg by yourself. The software contains many functions and features that have been developed within the GDI3D project, such as the 3D route planning, retrieving addresses and coordinates, links to an internet tourism portal in which you can find interesting information on local sights.

The XNavigator can be simply started via a Java Webstart link, all necessary software components will be downloaded. The software in programmed completely in Java and utilizes Java3D for the 3D rendering. The OpenGL hardware acceleration of the graphics card is used for high-performance 3D graphics, in addition to special software optimizations.

System Requirements:

1. min 1,5 GB RAM, recommended 2 GB RAM or more

2. Dual Core Processor

3. dedicated graphics card with at least 256 MB VRAM, OpenGL version 1.2 or higher

4. Internet connection with 4000 kbit/s or faster

5. Java Virtual Machine, version 6.0 or higher, preferably from Sun. Download here: http://java.sun.com/javase/downloads/index.jsp and install the Java Runtime Environment (JRE)

For best 3D performance we recommend to update the video driver to the latest version. Please visit the homepage of your notebook brand or the video chipset manufacturer, e.g. nVIDIA or ATI.


You can download the latest binaries here:

Download Page

Read the readme.txt carefully, it contains important information for installing and configuring the software

Start via Java Webstart:

Alternatively, XNavigator can be started directly from your browser using Java Webstart. The necessary software components are downloaded automatically, only Java has to be intalled. If you experience slow frame rates (actual frame rate does not match the displayed fps), try to download and install the software. For best performance we recommend not to use Webstart.

For Java Webstart, we offer 2 different pre-configured profiles. The settings for these profiles affect the overall visibility (distances at which objects can be seen), and hence the volume of data that will be transmitted, and the memory footprint. The profiles were tested against the specifications described below. If the profile doesn't work, please tell us using the feedback form.

Start with standard profile

e. g. Notebook or Desktop PC with dedicated graphics card, 1,5GB RAM, Dual Core CPU

Start with high profile

e. g. Workstation or game system, 4GB RAM, High End graphics card, Quad Core CPU

XNavigator Wiki:

In the Wiki you can find comprehensvie information on how to operate and configure the software and on troubleshooting.


If you have questions regarding the handling of the program, take a look at the Manual.


If you like to post remarks, suggestions, comments, or if you have further questions about the project or the 3D viewer, feel free to use our Feedback Fom.
