    // accept the defaults for color ramp, etc
    
    if (lasDatasetLayer.CanCreateRenderer(elevLasStretchRendererDef))
    {
      CIMTinRenderer renderer = lasDatasetLayer.CreateRenderer(elevLasStretchRendererDef);
      if (lasDatasetLayer.CanSetRenderer(renderer, SurfaceRendererTarget.Points))
        lasDatasetLayer.SetRenderer(renderer, SurfaceRendererTarget.Points);
    }
    
    
    // OR use a stretch renderer with stretchType standard Deviations
    var elevLasStretchStdDevRendererDef = new LasStretchRendererDefinition(ArcGIS.Core.CIM.LASStretchAttribute.Elevation);
    elevLasStretchStdDevRendererDef.StretchType = LASStretchType.StandardDeviations;
    elevLasStretchStdDevRendererDef.NumberOfStandardDeviations = 2;
    // accept the defaults for color ramp,  etc
    
    if (lasDatasetLayer.CanCreateRenderer(elevLasStretchStdDevRendererDef))

      CIMTinRenderer renderer = lasDatasetLayer.CreateRenderer(elevLasStretchStdDevRendererDef);
