Your computer must have a modern graphics card with an up-to-date driver.  The
source of most getting-up-and-running problems is an out-of-date graphics driver.
To get an updated driver, visit your graphics card manufacturer's web site.  This
will most likely be either NVIDIA, ATI or Intel. The drivers are typically under
a link named "Downloads" or "Support". If your computer is a laptop, then updated
drivers are probably at the laptop manufacturer's web site rather than the graphics
card manufacturer's.

Changes from WWJ SDK 0.5 to 0.6 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.
- Added a pre-render stage to the system, and implemented classes to create textures by drawing to the frame buffer or an FBO, most typically during the pre-render stage.

- 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


Change Summary for 0.4 to 0.5:
