The 'TSceneObject' class | Decker - 26 Jun 2003 | [ Top ]

Let me see, if I can explain what this class is all about. Mind you, I have not understanded it completly, so parts of this look-through explanation may be completly wrong. The idea of `TSceneObject` is to encapsulate the complex data structures and 3D-render API calls, in a general class interface for QuArK to use. It does not contain any code for a specific 3D-render, so one has to inherit from it and create a specialized class. The main function calls into this abstract class are the following: `procedure Init( ... ); virtual; abstract;` This function must; initialize the window, setup default data-structures and options, and ready the 3D-render API calls by for instance load a DLL. It is not defined in the TSceneObject class, as can be seen on the `abstract` keyword. So all classes that inherit from TSceneObject, must define the contents of this function. `procedure BuildScene( ... );` info missing... `procedure Render3DView; virtual; abstract;` info missing... `procedure AddPolyFace( ... );` info missing... `procedure AddModel( ... );` info missing... `procedure AddBezier( ... );` info missing... `procedure AddLight( ... ); virtual;` info missing...
