}14. 设置材料1void CD3DDlg::SetMaterial1(void)
{
D3DMATERIAL9 mtrl;
ZeroMemory(&mtrl,sizeof(D3DMATERIAL9));
mtrl.Diffuse.r=mtrl.Ambient.r=1.0f;
mtrl.Diffuse.g=mtrl.Ambient.g=1.0f;
mtrl.Diffuse.b=mtrl.Ambient.b=1.0f;
mtrl.Diffuse.a=mtrl.Ambient.a=1.0f;
m_pD3DDevice9->SetMaterial(&mtrl);
}15. 设置材料2void CD3DDlg::SetMaterial2(void)

mtrl.Diffuse.r=mtrl.Ambient.r=1.0f;
mtrl.Diffuse.g=mtrl.Ambient.g=1.0f;

m_pD3DDevice9->LightEnable(0,TRUE);
m_pD3DDevice9->SetRenderState(D3DRS_AMBIENT,D3DCOLOR_RGBA(32,32,32,0));
}17. 渲染 运行void CD3DDlg::Render(void)
{
m_pD3DDevice9->Clear(
0,
NULL,
D3DCLEAR_TARGET|D3DCLEAR_ZBUFFER,
D3DCOLOR_XRGB(0,0,255),

SetupMatrices();
SetLight();

m_pD3DDevice9->EndScene();
m_pD3DDevice9->Present(NULL,NULL,NULL,NULL);
}18. 释放资源void CD3DDlg::CleanUp(void)
{
m_pVB1->Release();
m_pVB2->Release();
m_pD3DTexture9->Release();
m_pD3DDevice9->Release();
m_pD3D9->Release();
}19. 最终该公有函数了 初始化 int CD3DDlg::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CWnd::OnCreate(lpCreateStruct) == -1)
return -1;
InitD3D9();
InitGeometry();
SetTimer(1,40,NULL);
return 0;
}20. 定时运行渲染void CD3DDlg::OnTimer(UINT_PTR nIDEvent)
{
Render();
m_nRotateY+=2;
CWnd::OnTimer(nIDEvent);
}21. 结束void CD3DDlg::OnDestroy()
{
CWnd::OnDestroy();
CleanUp();
}
谁解释也是白搭，仅仅有多练。只是推荐的就是抄程序也要抄对。
m_pD3DDevice9->CreateVertexBuffer( sizeof(vertices1), 0, D3DFVF_CUSTOMVERTEX1, D3DPOOL_DEFAULT, &m_pVB1, NULL);每个參数一行，至于什么函数分行写还是须要自己把握的。微软内部调用时第一个參数和函数同行。最后一个括号会再分一行，我认为不好就调成这种格式了。
