After you create an application window, you can begin initializing the essential DirectX objects you need to render the scene. For a Direct3D application, this entails creating and configuring DirectDraw, rendering surfaces, a rendering device, and a viewport.

The Triangle tutorial application performs system initialization in the InitDDraw application-defined subroutine, called from the Form_Load procedure. The steps executed in the InitDDraw subroutine are presented in the following sub-steps:

• Step 2.1: Initialize DirectDraw
• Step 2.2: Set Up DirectDraw Surfaces
• Step 2.3: Initialize Direct3D
• Step 2.4: Prepare the Viewport
