    Remarks
    Once you define a class breaks renderer, you can call a surface layer's CanCreateRenderer, CreateRenderer, CanSetRenderer and SetRenderer methods to create and assign a renderer to a surface layer.
    Example
    Create a TinLayer with renderers
    //Must be on the QueuedTask.Run()
    
    var tinCP_renderers = new TinLayerCreationParams(tinDataset);
    tinCP_renderers.Name = "My TIN layer";
    tinCP_renderers.IsVisible = true;
    
    // define the node renderer - use defaults
    var node_rd = new TinNodeRendererDefinition();
    
    // define the face/surface renderer
    var face_rd = new TinFaceClassBreaksRendererDefinition();
    face_rd.ClassificationMethod = ClassificationMethod.NaturalBreaks;
    // accept default color ramp, breakCount
    
    // set up the renderer dictionary
    var rendererDict = new Dictionary<SurfaceRendererTarget, TinRendererDefinition>();
    rendererDict.Add(SurfaceRendererTarget.Points, node_rd);
    rendererDict.Add(SurfaceRendererTarget.Surface, face_rd);
    
    // assign the dictionary to the creation params
    tinCP_renderers.RendererDefinitions = rendererDict;
    
    // create the layer
    var tinLayer_rd = LayerFactory.Instance.CreateLayer<TinLayer>(tinCP_renderers, MapView.Active.Map);
    Create a TerrainLayer with renderers
    //Must be on the QueuedTask.Run()
    
    var terrainCP_renderers = new TerrainLayerCreationParams(terrain);
    terrainCP_renderers.Name = "My LAS Layer";
    terrainCP_renderers.IsVisible = true;
    
    // define the edge type renderer - use defaults
    var edgeRD = new TinBreaklineRendererDefinition();
    
    // define the face/surface renderer
    var faceRD = new TinFaceClassBreaksRendererDefinition();
    faceRD.ClassificationMethod = ClassificationMethod.NaturalBreaks;
    // accept default color ramp, breakCount
    
    // define the dirty area renderer - use defaults
    var dirtyAreaRD = new TerrainDirtyAreaRendererDefinition();
    
    // add renderers to dictionary
    var t_dict = new Dictionary<SurfaceRendererTarget, TinRendererDefinition>();
    t_dict.Add(SurfaceRendererTarget.Edges, edgeRD);
    t_dict.Add(SurfaceRendererTarget.Surface, faceRD);
    t_dict.Add(SurfaceRendererTarget.DirtyArea, dirtyAreaRD);
    
    // assign dictionary to creation params
    terrainCP_renderers.RendererDefinitions = t_dict;
    
    //Create the layer to the terrain
    var terrainLayer_rd = LayerFactory.Instance.CreateLayer<TerrainLayer>(terrainCP_renderers, map);
    Slope Face Renderer - Equal Interval
    var slopeFaceClassBreaksEqual = new TinFaceClassBreaksRendererDefinition(TerrainDrawCursorType.FaceSlope);
    // accept default breakCount, symbolTemplate, color ramp
    
    if (surfaceLayer.CanCreateRenderer(slopeFaceClassBreaksEqual))
    {
      CIMTinRenderer renderer = surfaceLayer.CreateRenderer(slopeFaceClassBreaksEqual);
      if (surfaceLayer.CanSetRenderer(renderer, SurfaceRendererTarget.Surface))
        surfaceLayer.SetRenderer(renderer, SurfaceRendererTarget.Surface);
    }
    Slope Face Renderer - Quantile
    var slopeFaceClassBreaksQuantile = new TinFaceClassBreaksRendererDefinition(TerrainDrawCursorType.FaceSlope);
    slopeFaceClassBreaksQuantile.ClassificationMethod = ClassificationMethod.Quantile;
    // accept default breakCount, symbolTemplate, color ramp
    
    if (surfaceLayer.CanCreateRenderer(slopeFaceClassBreaksQuantile))
    {
      CIMTinRenderer renderer = surfaceLayer.CreateRenderer(slopeFaceClassBreaksQuantile);
      if (surfaceLayer.CanSetRenderer(renderer, SurfaceRendererTarget.Surface))
        surfaceLayer.SetRenderer(renderer, SurfaceRendererTarget.Surface);
    }
    Elevation Face Renderer - Equal Interval
    var elevFaceClassBreaksEqual = new TinFaceClassBreaksRendererDefinition();
    // accept default breakCount, symbolTemplate, color ramp
    
    if (surfaceLayer.CanCreateRenderer(slopeFaceClassBreaksEqual))
    {
      CIMTinRenderer renderer = surfaceLayer.CreateRenderer(slopeFaceClassBreaksEqual);
      if (surfaceLayer.CanSetRenderer(renderer, SurfaceRendererTarget.Surface))
        surfaceLayer.SetRenderer(renderer, SurfaceRendererTarget.Surface);
    }
