Back

Changes from WWJ SDK v0.5 to v0.6 early access - March 6, 2009
------------------------------------------------------------------------
  • New Airspace shapes and volumes, terrain conformant. See render.airspaces package and examples.Airspaces and AirspaceBuilder
  • New rubber sheet images. See util.ImageUtil and examples.RubberSheetImage
  • New measure tools. See util.measure package and examples.MeasureToolUsage
  • New 'on-screen display' layers: ViewControlsLayer, LayerManagerLayer and StatusLayer
  • New ContourLine renderable primitive. See examples.ContourLines
  • New Web Service Catalog support. See applications.gio

  • Data import and installation:
    • Local imagery and elevation import into WWJ cache format - see data.TiledImageProducer and data.TiledElevationProducer
    • Reading, writing, and discovery of file descriptors for WWJ cache format - see cache.FileStore and data.DataDescriptor
    • Discovery and conversion of WWJ.Net cache format - see data.WWDotNetDataLayerSetReader and data.WWDotNetLayerSetInstaller

  • New DDS compressor with support for mipmaps - see formats.dds.DDSCompressor

  • Icon layer and renderer allow to use absolute elevations, apply horizon and view clipping
  • Applet package updated for Sun Next Generation Java plugin support
  • Conpound and local elevation models. See terrain package
  • FlatWorld example updated with round/flat globe switching code
  • Track markers updated - see render.markers package, layers.MarkerLayer and examples.MarkersOrder
  • PlacenameLayer updated - see layers.placename package and examples.Placenames
  • TerrainProfileLayer new 'follow path' mode - see examples.MeasureToolUsage
  • Terrain intersection test for Line and elevation. See terrain.SectorGeometryList and render.ContourLine
  • On-screen layers display location offset - see layers.Compass, WorldMap, Scalebar...
  • New format support: tab, tiff and world file - see format package
  • Tiled image layers alpha blending fixed and mipmap support.
  • New examples.util package - browser launcher, audio and slides players, image viewer...

  • Data driven navigation sensitivity settings - see awt.ViewInputAttributes.
  • Redesigned OrbitViewInputBroker as ViewInputHandler - see awt.ViewInputHandler. Improved navigation near the terrain, and made it easier for applications to extend or modify the navigation behavior.
  • Sharper image-based surface shapes. Experimental geometry based surface shapes.
  • Experimental hybrid tessellator to better handle the poles.
  • Improved WMS server
  • Image transformation and reprojection utilities. See util.ImageUtil.
  • New Ant build structure.
  • Collision detection demo.
  • New network status host available/unavailable events.

  • Refactoring
    • Position is now a LatLon subclass

  • On hold
    • Fog layer produces artifacts with the new tiled image layer premultiplied alpha blending and has been removed
    • Remote surface images are being reworked into a more generic scheme
