Prototype Java implementation of query language interfacing to IAKS XTrack
Installation instructionsThe demonstration consists of two parts both packed in a java archive file: A java 3D modelviewer for preselected queries and a set of trajectory data from the Iaks XTrack. You will need Java 1.4.0_01 and Java3D 1.3.1 to run the demo. 512MB or more memory is recommended to run the demo.Step 1: (check java installation)Check the java installation on the machine(s) were you want to run the demo by running:java -version on the command line. Here is the output from the linux machine were the demostration was tested: java version "1.4.0_01" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0_01-b03) Java HotSpot(TM) Client VM (build 1.4.0_01-b03, mixed mode) Step 2: (check Java3D installation)change directory to the Java Runtime Environment directory. Look for libs from Java3D in .../jre/lib/i386/ named:libJ3D.so, libJ3DUtils.so, libj3daudio.so, ... If there are none, you can get Java3D at the Java 3D Download Page: [Windows/Solaris] , [Linux] . Installation instructions can be found for the platforms at Java 3D Installation Notes: [Windows/Solaris] , [Linux] |
Step 3: (download the archives)Download the software from below and put all in a directory, where you want to run it.[Download the Demo] [Download the Trajectory Files] Step 4: (unpack the examples)Unpack the Trajectories in the archive by running:jar xfv Trajectories.jar on the command line. Step 5: (run the Demo)To start the demo on your machine typejava -Xmx200m -jar DemoQuery.jar on the command line. The option -Xmx200m increases the maximum heap size of the Java Virtual Machine to 200MB. Omitting the option will lead to an "out of memory" exception, when constucting a 3D model. An explanation of the demo... can be found in the [demo's leaflet]. |
