Methods don t have these constraints, as you can see by revisiting the method implementation TranslationServices.DoTranslation: public void DoTranslation<Control1, Control2>(Control1 src, Control2 dest) { _adapter.SetValue(dest, _translation.Translate(_adapter.GetValue<Control1, string>(src))); } The variable _adapter is an interface instance of IControlAdapter. The method GetValue retrieves the value of a control, and then assigns the value of the control using SetValue. Generic parameters are used at the method level to make it possible to use any data type. Of course, it goes without saying that when using Generics at the method level without constraints, you ll have to use typecasts. Following is an implementation of IControlAdapter for the System.Windows.Forms namespace: private class WindowsAdapter: Abstractions.IControlAdapter { public type GetValue<ControlType, type>(ControlType control) where type: class { if(control is TextBox) { TextBox cls = control as TextBox; return cls.Text as type; } return default(type); } public void SetValue<ControlType, type>(ControlType control, type value) { if(control is TextBox) { TextBox cls = control as TextBox; String strValue = value as String; cls.Text = strValue; } } } In the implementation of the GetValue and SetValue methods, notice how dynamic typecasting and type checking is used in the form of is and as statements. Using dynamic casting and dynamic checking allows the adapter implementation to check which kind of controls are being passed and then perform an appropriate action. For example, for the GetValue method in the case of a TextBox, it means retrieving the text contents. If the control were a check box, then it would mean retrieving a checked or unchecked value. The same sorts of rules apply for the SetValue method. The value of the adapter is evident if a different toolkit needs to be implemented. In that case, the only requirement is to implement a new IControlAdapter implementation as illustrated by the following wx.NET example:

Figure 6-12 The three steps in deferred rendering As discussed, this whole operation happens only one time, using one pass of a single effect As a result, this operation takes the same effort as rendering your scene the usual way without lighting calculations (or less, because the effect is very simple) Now take your time to understand the following lines For each pixel of your screen, you have stored the depth in a texture For each pixel, you also know its 2D screen coordinate, because it s the same as its texture coordinate This means that some way or another, for each pixel of your screen you should be able to re-create the original 3D position Furthermore, you have stored the 3D normal of each pixel.
