// some details shown in Listing 13.4
Step 2: initialize selected hardware and set the coordinate system parameters.
m _ pD3DDevice->SetFVF(D3DFVF _ XYZ | D3DFVF _ DIFFUSE);
m _ pD3DDevice->SetRenderState(D3DRS _ CULLMODE, D3DCULL _ NONE);

// matrix computation, loading of the WORLD , VIEW and PROJECTION matrix processors
details are in Listing 14.4
.
Step 3: clear drawing buffer and draw two squares.
m _ pD3DDevice->Clear( ... ); // detailed in Listing 13.5
.
// First TRIANGLEFAN: The Large Square
v[0].m _ point = D3DXVECTOR3 (-4,0,4);

// Vertex V a

v[1].m _ point = D3DXVECTOR3 (4,0,4);

// Vertex V b
