public class TLcyOGC3DTilesAddOn extends ALcyFormatAddOn

This add-on provides support for OGC 3D tiles data sets, like for example Cesium tilesets.

Note: this add-on only adds support for decoding OGC 3D tiles data sets, not for visualization. Visualization is only supported in a Lightspeed view and additionally requires the TLcyLsp3DTilesFormatAddOn add-on.

By default, this add-on does not install an ILcdInputStreamFactory on the 3D Tiles decoder. The decoder then uses its built-in high-performance HTTP client, and HTTP authentication is picked up automatically from ILcdPasswordProvider implementations registered as services (see LcdService). Set the configuration option TLcyOGC3DTilesAddOn.useInputStreamFactory=true in TLcyOGC3DTilesAddOn.cfg to route all 3D Tiles I/O through the input stream factories registered in the Lucy back-end instead. Enable this only when you need a non-HTTP transport such as S3: once set, the factory is used for every source, which bypasses the built-in client and is slower for HTTP.

    • plugInto

      public void plugInto(ILcyLucyEnv aLucyEnv)
      Description copied from class: ALcyFormatAddOn

      Creates and plugs in the add-on's format.

      Overrides:
      plugInto in class ALcyFormatAddOn
      Parameters:
      aLucyEnv - the Lucy environment to plug into

    • createBaseFormat

      protected ALcyFormat createBaseFormat()
      Description copied from class: ALcyFormatAddOn

      Returns a new data format for this add-on. Override this method to extend the default format with new functionality.

      For example, to alter the icon of the layers of this format, you can decorate the layer factory created in the format: 

      
 @Override
 protected ALcyFormat createBaseFormat() {
   return new ALcyFormatWrapper(super.createBaseFormat()){
     @Override
     protected ILcdGXYLayerFactory createGXYLayerFactory(){
       final ILcdGXYLayerFactory delegate = super.createGXYLayerFactory();
       return new ILcdGXYLayerFactory(){
         @Override
         public ILcdGXYLayer createGXYLayer(ILcdModel aModel){
           ILcdGXYLayer layer = delegate.createGXYLayer(aModel);
           if (layer != null){
             ILcdIcon icon = ...;
             layer.setIcon(icon);
           }
           return layer;
         }
       }
     }
   }
 }
      Specified by:
      createBaseFormat in class ALcyFormatAddOn
      Returns:
      a new format for this add-on

    • createFormatWrapper

      protected final ALcyFormat createFormatWrapper(ALcyFormat aBaseFormat)
      Description copied from class: ALcyFormatAddOn

      Returns a new data format wrapper for this add-on. A format wrapper extends the base format with aspects such as asynchronous painting, mutable file behavior, safe guarding, etc.

      Overriding this method of an existing add-on should be done with extreme care as add-ons typically rely on the wrappers that should be present (e.g. a safe guard).

      Specified by:
      createFormatWrapper in class ALcyFormatAddOn
      Parameters:
      aBaseFormat - the base format to wrap
      Returns:
      a new format for this add-on
