示例1: DetectOcclusions
/// <summary>
/// Traverse from the bottom right of the scene graph (top visible node)
/// up the tree determining which parent nodes are occluded by their children
/// nodes.
/// </summary>
/// <param name="n">The node to find occlusions for.</param>
/// <param name="pickPath">
/// A pick path representing the bounds of <c>n</c> in parent coordinates.
/// </param>
/// <remarks>
/// Note that this is only detecting a subset of occlusions (parent, child),
/// others such as overlapping siblings or cousins are not detected.
/// </remarks>

if (n.FullIntersects(pickPath.PickBounds)) {

// this child must also be occluded
each.Occluded = true;

}示例2: Accept
/// <summary>
/// Returns true if the node's bounds intersects the bounds specified by the
/// BoundsFilter.
/// </summary>
/// <remarks>
/// For a node to be accepted, it must also satisfy the following conditions:
/// it must be pickable, it must not be the marquee node, it must not be a
/// selectable parent, and the it must not be a layer that is viewed by a camera
/// that is a selectable parent
/// </remarks>
/// <param name="node">The node to test.</param>
/// <returns>True if the node is accepted; otherwise, false.</returns>
