Nasa java world wind9/24/2023 ![]() Replacement as specified through the Java property exists at run-time and can be found via the classpath,Ĭonfiguration values specified by that mechanism are given precedence over values specified by the new mechanism. World Wind no longer contains a worldwind.properties file. These mechanisms remain available but are deprecated. An alternate file could be specified via the Note: Prior to September of 2009, configuration properties were read from the fileĬonfig/worldwind.properties. Not retroactive so affect only Configuration queries made subsequent to setting the value. ![]() See config/worldwind.xml for documentation on setting configuration values.Ĭonfiguration values can also be set programatically via setValue(String, Object), but they are Applications usually specify an override document in order to specify the initial layers in the World Wind overrides only those values in this application document, it leaves all others to the value specified in World Wind jar files are typically on the classpath, in which case the configuration file may be in the jar file.)Īdditionally, an application may set another Java property, .config.document, to aįile name or URL whose contents contain configuration values to override those of the primary configuration document. If a file is specified its location must be on the classpath. When an application specifies a different configuration location it typically does so in its main method prior The Java property .file to a different file name or a valid URL prior toĬreating any World Wind object or invoking any static methods of World Wind classes, including the ConfigurationĬlass. The default World Wind configuration document is config/worldwind.xml. During construction that class causes World Wind's internal classes toīe constructed, using the names of those classes drawn from the Configuration singleton, this class. For example, the first World Wind object created by an application is typically a WorldWindowGLCanvas. Many World Wind start-up objects query this information to determine the classes toĬreate. The information can subsequently be retrieved via the class' various When the Configuration class is first instantiated it reads the XML document config/worldwind.xml and It is constructed upon first use of any of its static methods. The Configuration class is a singleton, but its instance is not exposed publicly. Including the globe, elevation model and layers, and various control quantities such as cache sizes and data Configurations files contain the names of classes to create at run-time, the initial model definition, It reads World Wind configuration files and registers theirĬontents. The site includes a number of useful resources and demonstrations for the Web World Wind Javascript API.This class manages the initial World Wind configuration. The site includes a number of useful resources and demonstrations. This site includes the full source plus daily builds and the API documentation. The NASA World Wind SDK can be freely downloaded from the WorldWind site. ![]() EarthNav Lite, a desktop application used to view, manage, and visualize high resolution data.Īn in-house application used to create high resolution key-frame animations.Using the World Wind SDK, Tekmap Consulting has developed a number of custom applications including:Ī public access kiosk used at the Bedford Institute of Oceanography. To run a WorldWind demo application, visit the. The World Wind SDK can be used to create dynamic desktop applications or web enabled pages with Web World Wind javascript API. WorldWind is an SDK (software development kit) that software engineers can use to build their own applications. If this DrawContext is associated with a GLJPanel, the returned width is the power-of-two ceiling of the viewport, and is therefore almost always larger than the GL viewport width. The returned width is potentially different from the GL viewport width. Examples include playing a key role in NASA space. Indicates the width in pixels of the drawing target associated with this DrawContext. World Wind is a cross-platform SDK that allows developers to easily create interactive applications for visualizing geospatial data in 3-D. The companys software powers generation after generation of the safest, most secure systems in the world. NASA World Wind is an open source software development kit (SDK) written in Java. ![]()
