![]() ![]() This error indicates that WorldWind is running in a 64-bit Java Virtual Machine, but attempting to load a 32-bit version of JOGL (the Java OpenGL binding). WorldWind 2.0 manages the loading of 32-bit and 64-bit versions of JOGL automatically. Note: This problem applies to WorldWind 1.5 and earlier. The texture control is explicit because pushing and popping texture state is expensive. Notice that WorldWind’s OGLStackHandler class is used to push and pop an identity projection matrix. OGLStackHandler osh = new OGLStackHandler() The best practice is to set state within a try block with a finally clause that performs the restoration, like this: GL2 gl = dc.getGL().getGL2() // Get JOGL's GL2 interface from the draw context. It could also happen when an exception occurred after the OpenGL state is set but before it’s restored. The most common mistake is failure to push and pop attribute masks or transforms for the state changed by the drawing code.Ģ. And if one class does not restore the state, everything subsequently drawn will likely be incorrect in some way. If the inherited state is different from the default, the shape will likely display incorrectly. All WorldWind shapes assume they inherit the default OpenGL state when they draw. If you’re using classes that you’ve created or extended, and they draw using OpenGL, be sure they restore the OpenGL state to what it was when given control. If they’re in feet instead, all the shapes will be larger than expected. WorldWind assumes all linear measures such as elevation, altitude and length are in meters. Problem: My shapes are bigger than they’re supposed to meīe sure the shapes are specified in meters. on a separate thread, they could occur while the model is being drawn and the drawing thread could encounter inconsistent or incoherent state. If changes are made to shapes, layers, views, etc. Be sure to make changes to WorldWind on the event dispatch thread (EDT).WorldWind does redraw in response to its input handler or when data requested from a server arrives. ![]() Apps usually make several changes in reaction to user requests, Redrawing at every one of those intermediate changes would show intermediate states and decrease performance. WorldWind does not automatically update the screen when the app makes changes. Be sure to call WorldWindow.redraw() when you’ve finished making changes to shapes, layers, the view, or anything else.Problem: The change I made didn’t show up on the screen Installing updated drivers almost always fixes the problem. If you still need help or have questions, please search/post on the forum or GitHub. The problem arises in the URLConnection class not following the protocol redirection provided by the server. Specifying an HTTPS endpoint on an older WorldWind Java version will work. All versions of WorldWind Java support HTTPS, as WorldWind is using the Java URLConnection class. The configuration files have been maintained with a deprecated comment in order to maintain your on disk cache of the data. Please note some WMS layer sources have been deprecated in v2.1.0. In addition to HTTPS endpoints specified by default, there are a number of improvements and bug fixes. To summarize, the best option, if available, is to update to v2.1.0. This class is a copy of the NASAWFSPlaceNamesLayer class but updates the hard coded service link to HTTPS. The patch jar includes a new PlaceNames layer: NASAWFSPlaceNamesLayerHttps.java. $ java .config.document=worldwind-2.0.0-https-patch/worldwind-https-patch.xml Place the jar in the classpath of your project and add the following argument to your application launch script. WorldWind Java v2.1.0 uses HTTPS map layers exclusively. SDK v2.1.0 and v2.0.0 are interface compatible.ĭownload the WorldWind Java v2.0.0 HTTPS Patch jar from GitHub. Option 1: Upgrade to WorldWind Java v2.1.0 (Preferred) SEVERE: Retrieval returned no content for You may see the following errors: FINE: Response code 301, Content length 534, Content type text/html charset=iso-8859-1, retrieving Clients map layer configuration files must be updated to use HTTPS endpoints. The Java URLConnection class does not follow the redirect protocol. HTTP requests return a redirect to the HTTPS endpoint. Problem: NASA Map Layers do not download (HTTP 301)Īs of January 2017 WorldWind map servers (worldwind*., .gov, and .gov) exclusively use HTTPS. Those problems and their fix are listed here. Many problems encountered by WorldWind developers and their application users have common causes.
