Classes representing graphics as hierarchical 3d tiles.

Classes

Name Description  
BingElevationProvider Provides an interface to the Bing Maps elevation services.  
BingLocationProvider Provides an interface to the Bing Maps location services.  
DisclosedTileTreeSet A set of TileTrees disclosed by a set of objects implementing TileTreeDiscloser, used to collect references to tile trees in use by those objects.  
EllipsoidTerrainProvider A terrain mesh provider that produces geometry that represents a smooth ellipsoid without any height perturbations.  
GeographicTilingScheme A MapTilingScheme using a simple geographic projection by which longitude and latitude are mapped directly to X and Y.  
ImageryMapLayerTreeReference A reference to one of our tile trees.  
MapCartoRectangle A specialization of Range2d representing a Cartographic region on the surface of the Earth,  
MapLayerTileTreeReference A TileTreeReference to be used specifically for MapTileTrees.  
MapTile A Tile belonging to a MapTileTree representing a rectangular region of a map of the Earth.  
MapTileProjection Projects points within the rectangular region of a MapTile into 3d space.  
MapTileTree A quad tree consisting of MapTiles representing the map imagery draped onto the surface of the Earth.  
MapTilingScheme A scheme for converting between two representations of the surface of the Earth: an ellipsoid and a rectangular tiled map.  
QuadId Identifies a node within a quad tree, such as a MapTile within a MapTileTree.  
RealityTile A Tile within a RealityTileTree, representing part of a reality model (e.g., a point cloud or photogrammetry mesh) or 3d terrain with map imagery.  
RealityTileTree Base class for a TileTree representing a reality model (e.g., a point cloud or photogrammetry mesh) or 3d terrain with map imagery.  
TerrainMeshProvider Provides 3d meshes representing terrain for display in a Viewport.  
TerrainProviderRegistry A registry of TerrainProviders identified by their unique names.  
Tile A 3d tile within a TileTree.  
TileAdmin Manages Tiles and TileTrees on behalf of IModelApp.  
TileDrawArgs Provides context used when selecting and drawing Tiles.  
TileGeometryCollector Collects geoemtry from a GeometryTileTreeReference within a specified volume at a specified level of detail.  
TileRequest Represents a pending or active request to load the contents of a Tile.  
TileRequestChannel A channel over which requests for tile content can be made.  
TileRequestChannels A set of named TileRequestChannels via which content for Tiles can be requested.  
TileRequestChannelStatistics Statistics regarding the current and cumulative state of one or more TileRequestChannels.  
TileTree A hierarchical level-of-detail tree of 3d Tiles to be rendered in a Viewport.  
TileTreeReference A reference to a TileTree suitable for drawing within a Viewport.  
TileUsageMarker A marker associated with a Tile to track usage of that tile by any number of TileUsers.  
WebMercatorTilingScheme A MapTilingScheme using the EPSG:3857 projection.
