    SetVerticalExaggeration Method (VoxelLayer)
    In This Topic
    Sets the vertical exaggeration. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax
    public void SetVerticalExaggeration( 
       double value
    )
    Public Sub SetVerticalExaggeration( _
       ByVal value As Double _
    ) 

    Parameters

    value
    Exceptions
    ExceptionDescription
    This method or property must be called within the lambda passed to QueuedTask.Run
    Example
    Lighting Properties, Offset, Vertical Exaggeration
    //var voxelLayer = ... ;
    //Must be on the QueuedTask.Run()
    
    //Offset
    var offset = voxelLayer.CartographicOffset;
    //apply an offset
    voxelLayer.SetCartographicOffset(offset + 100.0);
    
    //VerticalExaggeration
    var exaggeration = voxelLayer.VerticalExaggeration;
    //apply an exaggeration
    voxelLayer.SetVerticalExaggeration(exaggeration + 100.0);
                
    //Change the exaggeration mode to "ScaleZ" - corresponds to 'Z-coordinates' 
    //on the Layer properties UI - must use the CIM
    var def = voxelLayer.GetDefinition() as CIMVoxelLayer;
    def.Layer3DProperties.ExaggerationMode = ExaggerationMode.ScaleZ;
    //can set vertical exaggeration via the CIM also
    //def.Layer3DProperties.VerticalExaggeration = exaggeration + 100.0;
    
    //apply the change
    voxelLayer.SetDefinition(def);
    
    //Diffuse Lighting
    if (!voxelLayer.IsDiffuseLightingEnabled)
        voxelLayer.SetDiffuseLightingEnabled(true);
    var diffuse = voxelLayer.DiffuseLighting;
    //set Diffuse lighting to a value between 0 and 1
    voxelLayer.SetDiffuseLighting(0.5); //50%
    
    //Specular Lighting
    if (!voxelLayer.IsSpecularLightingEnabled)
        voxelLayer.SetSpecularLightingEnabled(true);
    var specular = voxelLayer.SpecularLighting;
    //set Diffuse lighting to a value between 0 and 1
    voxelLayer.SetSpecularLighting(0.5); //50%
