Applications written in C++ use the IDirect3D7 interface to create Direct3D rendering devices and vertex buffers. A Direct3D application creates a rendering device by invoking the IDirect3D7::CreateDevice method. For details, see Direct3D Devices. The rendering device encompasses the rendering, lighting, material, and viewport states.

Call the IDirect3D7::CreateVertexBuffer method to create a vertex buffer. Vertex buffers contain vertex data specially prepared for faster rendering than simple arrays of vertex data. For more information, see Vertex Buffers.

Applications written in Visual Basic use the methods of the Direct3D7 class to create Direct3D rendering devices and vertex buffers. A Direct3D application creates a rendering device by invoking the Direct3D7.CreateDevice method. For details, see Direct3D Devices. The rendering device encompasses the rendering, lighting, material, and viewport states.
