TForm3D = class(TCustomForm3D)
class PASCALIMPLEMENTATION TForm3D : public TCustomForm3D
TForm3D represents a standard FireMonkey 3D application window.
To create 3D forms, you have to create a new FireMonkey 3D application first. Then you can create 3D forms in the Form Designer at design time. These forms are implemented as descendants of TForm3D. 3D forms can represent the application's main window, dialog boxes, or other. A 3D form can contain FireMonkey 3D objects, such as TText3D, TGrid3D, and so on.
All the objects that can be employed in 3D forms reside in the Objects3D unit.
