CHANGELOG

v.1.1.0

08/01/2017

Please note: our next release will end support for the Unity 5.x lifecycle. We look forward to taking advantage of Unity 2017 optimizations and features.

Upgrade Instructions
  • As always, please remove older versions before installing!
  • TypeFilter now uses an array. You will need to update your filters!
  • MeshFactory is obsolete. Please replace with VectorTileFactory or StyleOptimizedVectorTileFactory.
  • PoiVisualizer is obsolete. Please use a standard VectorLayerVisualizer with a PrefabModifier.
  • Triangle.NET has been replaced with Earcut. If you were using Triangle features, you will need to import that library yourself.
  • If you were using a RangeTileProvider, you will need to update its parameters, which are now described in terms of North, East, South, and West (for readability).
  • ChamferModifier has been replaced with ChamferHeightModifier. This new version looks and performs better.
  • Ensure your MapImageFactories have the expected Map Id! We've updated the way Ids are serialized, and your old Ids may have been lost--sorry!
Memory/Performance
  • Added support for style-optimized vector tiles! Read more here.
    • You will need to use the new StyleOptimizedVectorTileFactory.
    • This can result in far less data transfer/data processing.
  • Replaced Triangle.NET with Earcut which results if much faster geometry construction.
  • Removed expensive string concatenation process in FeatureBehaviour.
  • MeshFactory no longer waits for Terrain or Raster results before making its own web request.
New Features
  • Added ability to cache successful tile requests to disk (via SQL database). If a tile is found in the database, it will not make a web request.
    • Note that tiles in this database only expire when the cache fills up!
  • Want to create a low-poly landscape? Use the new LowPolyTerrainFactory!
  • Maps can now be snapped to y=0 (this prevents the need to reposition your camera at higher elevations).
  • Added ability to choose pivot of objects generated with the ModifierStack (tile center, first vertex, or vertex average).
  • Use the new GameObjectModifier AddMonoBehavioursModifier to "generically" add Components to your game objects.
  • Added ability to snap to terrain/other objects with SnapTerrainRaycastModifier. This is more accurate (but slower) than SnapTerrainModifier.
  • Added "example" SpawnInsideModifier which can be used to add procedural decoration inside a mesh (for example, Landuse).
  • Added ChamferHeightModifier which, obviously, combines Chamfer and Height modifiers.
  • Added GlobeTileProvider to request the entire world at once (be advised that this may result in MANY tile requests!).
  • Project your tiles on a sphere! Use the new GlobeTerrainFactory to make a globe.
  • Added ability to pick a custom style from the Mapbox Styles API.
    • Use the search button and enter your user name (for Mapbox Studio).
    • Note that this requires you to create an API token that supports styles:list!
Bug Fixes
  • WebGL builds now work as expected!
  • Fixed Unity Cloud Build and iOS signing issues that were related to native iOS libraries.
  • Map tiles are now parented correctly to the map root (on device). If you previously had trouble rotating/moving/scaling a map on device, fret no longer!
  • Fixed some bad height calculations for buildings.
  • PolygonModifier now correctly generates holes and better handles multiple parts.
  • Tiles should now wrap at world boundaries correctly (rather than producing invalid tile requests).
Improvements
  • Unity/C# warnings have been addressed.
  • Added preprocess build step and a unit test that checks for duplicate Android libraries.
  • Example CameraMovement script has been improved to allow for mouse wheel translational zoom and precise touch drag (for panning).
  • Added option to remove sidewalls from height-extruded geometry (for roads, for example).
  • Use VertexDebugger to debug vertices for procedurally generated meshes.
  • Added timeout exception to HttpRequest.
  • RangeTileProvider is now more readable.
New Examples
  • See Globe example for one method of spherically projecting tiles.
  • MeshGenerationBasics has new interactive elements to demonstrate some of the new features we've added.
  • StylingDemoMeshGeneration uses SpawnInsideModifier to add "bushes" to landuse:park.
  • Check TerracedWorld to see an example of how to use contour data to generate Godus-like worlds.

v.1.0.0

05/26/2017

Memory/Performance
  • Added support for runtime texture compression (DXT) in the MapImageFactory
  • MapVisualizer now pools gameobjects/textures/data to avoid instantiation and destruction costs
  • TerrainFactory now allocates less memory when manipulating geometry
  • Elevation textures are no longer held in memory and height data parsing and access is much faster
  • Added new FlatTerrainFactory that is optimized specifically for flat maps
  • Tiles can now be cached in memory—configure the cache size in MapboxAccess.cs (default size is 500)
  • Slippy maps now dispose tiles that determined to be "out of range"
    • Tiles that are out of range before completion are properly cancelled
  • Terrain generation in Unity 5.5+ should be much faster and allocate less memory
New Features

  • Added new retina-resolution raster tiles

  • Added mipmap, compression, and retina-resolution support to MapImageFactory

  • The PoiGeneration example now includes clickable 3D world-space gameobjects—use these as reference for placing objects in Unity space according to a latitude/longitude

  • MapVisualizer and TileFactories now invoke state change events—use these to know when a map or specific factory is completed (loaded)

    • See an example of implementing a loading screen in Drive.unity

  • You can now specify GameObject Layer for tiles in the TerrainFactory

  • Add colliders to your terrain by checking the Add Collider flag in the TerrainFactory

  • Add colliders or specify GameObject Layer for buildings, roads, etc. with ColliderModifier and LayerModifier

Bug Fixes
  • Building snapped to terrain are now rendered correctly (check Flat Tops in the HeightModifier)
  • Web request exceptions are now properly forwarded to the Response (should fix Unknown tile tag: 15)
  • Complex building geometry should now be rendered correctly (holes, floating parts, etc.)
  • Materials assigned to a TerrainFactory are now properly applied at runtime
  • Because of UnityTile pooling, you should no longer encounter key already exists in dictionary exceptions related to tile factories—this means you can change map attributes (location, zoom, terrain, etc.) at runtime without throwing exceptions
Improvements
  • Map configuration values are no longer static, and an OnInitialized event is invoked when the AbstractMap reference values have been computed (prevents temporal coupling)
  • Snapping to terrain has been simplified—just add a SnapToTerrainModifier to your ModifierStack
  • Slippy.cs has been refactored to CameraBoundsTileProvider.cs and the backing abstraction enables you to write your own tile provider system (zoomable, path-based, region, etc.)
  • MapController.cs has been refactored to AbstractMap —this is not yet abstract, but should provide an example of how to construct a map using a MapVisualizer and a TileProvider
  • UnityTile has been refactored to support reuse and has the ability to cancel its backing web requests
  • DirectionsFactory no longer relies on a MapVisualizer or DirectionsHelper, but can still use existing MeshModifiers
