示例1: ToneMap

/// Tone-maps a texture into another. The target dimensions,
/// source dimensions, and ToneMapper dimensions <b>must</b>
/// be exactly the same for correct operation.
/// </summary>
/// <param name="context">The device context.</param>
/// <param name="pass">A SurfacePass instance.</param>
/// <param name="target">The render target.</param>
/// <param name="source">The source texture.</param>

}示例2: Diffract

/// <param name="destination">The destination render target view.</param>
/// <param name="source">The source texture, can be the same resource as the render target.</param>
/// <param name="fNumber">The distance at which to evaluate the aperture transmission function.</param>
