The worldwind java sdk has finally been released. It’s a neat SDK, well organized, easy to bring into Eclipse with some good examples to start hacking away.

The only problem is the examples are written in Java

. If braces make you cringe but you still want to work with all the

excellent Java libraries out there, you’ll want to take a look at

Jython. Taking the AWT1Up.java code and porting a subset of the

functionality to Jython was surprisingly easy and yielded much more

readable code in my opinion. And the ability to manipulate objects at

the interactive prompt is just so sweet.



View the Source Code

Setup is not too terrible:

  1. Get a Java JDK (I’m using sun java 6)

  2. Download and install Jython 2.2b2

  3. Download and unzip the worldwind java sdk (ex: /opt/wwj )

  4. Set your LD_LIBRARY_PATH variable to /opt/wwj

  5. Set your CLASSPATH variable to /opt/wwj/worldwind.jar

  6. Run jython wwj_demo.py

One

thing that is a bit disappointing with the WorldWind SDK in general is

the lack of support for rendering common formats. Maybe I missed

something but I couldn’t get gpx or georss feeds working properly. It

is version 0.2 so I expect support for GeoRSS and GPX to improve and

for GML, KML, GeoJSON, Shapefiles, Rasters, WMS, etc to be included

eventually.

Anyone else out there started playing with Jython / Worldwind yet?
