DX中灯光和材质续

 假如设置这样的顶点格式：

1. #define D3DFVF_CUSTOMVERTEX (D3DFVF_XYZ)//灵活顶点格式
3. struct CUSTOMVERTEX 
4. {
5.     D3DXVECTOR3 position;
6. };

 

他告诉我们，顶点是未进行坐标转换和光照处理的，须我没手动处理，如果我们未处理会是怎样呢？

293.     return 0;
294. }

 

上面即不进行坐标变换也不进行光照处理，结果屏幕右下角部分显示一个黑色的三角形

 

2 添加坐标变换：

1. /*==========================================
2. Function name: ChangeWorld
3. Description: 坐标变换和设置摄像机
4. ==========================================*/
5. HRESULT ChangeWorld()
6. {
7.     D3DXMATRIXA16 matWorld;
8.     D3DXMatrixIdentity(&matWorld);
9.     g_pD3DDev->SetTransform(D3DTS_WORLD, &matWorld);
11.     D3DXMATRIXA16 matView;
12.     D3DXMatrixIdentity(&matView);
13.     D3DXVECTOR3 eyeVec (0.0f, 0.0f, -4.0f);
14.     D3DXVECTOR3 lookVec(0.0f, 0.0f,  0.0f);
15.     D3DXVECTOR3 upVec  (0.0f, 1.0f,  0.0f);
16.     D3DXMatrixLookAtLH(&matView, &eyeVec, &lookVec, &upVec);
17.     g_pD3DDev->SetTransform(D3DTS_VIEW, &matView);
19.     D3DXMATRIXA16 matProj;
20.     D3DXMatrixIdentity(&matProj);
21.     D3DXMatrixPerspectiveFovLH(&matProj, D3DX_PI/4, 1.0f, 1.0f, 100.0f );
22.     g_pD3DDev->SetTransform(D3DTS_PROJECTION, &matProj);
24.     return S_OK;
25. }

 

结果三角形变小了，显然是经过了坐标变换，然后投影到屏幕上来。

 

3 添加材质：

1. /*==========================================
2. Function name: SetUpLightAndMatrial
3. Description: 设置
4. ==========================================*/
5. HRESULT SetUpLightAndMatrial()
6. {
7.     D3DMATERIAL9 d3dMat;
8.     ZeroMemory(&d3dMat, sizeof(D3DMATERIAL9));
9.     d3dMat.Ambient.a = d3dMat.Diffuse.a =1.0f; 
10.     d3dMat.Ambient.r = d3dMat.Diffuse.r =0.0f; 
11.     d3dMat.Ambient.g = d3dMat.Diffuse.g =1.0f; 
12.     d3dMat.Ambient.b = d3dMat.Diffuse.b =1.0f;
13.     g_pD3DDev->SetMaterial(&d3dMat);
15.     return S_OK;
16. }

 

设置环境光颜色

1. g_pD3DDev->SetRenderState(D3DRS_AMBIENT, 0x00202020);

现在我们的三角形有颜色了

 

4 添加光照：

添加光照比较麻烦些，须在以下几点改改

（1）修改顶点格式：

1. #define D3DFVF_CUSTOMVERTEX (D3DFVF_XYZ | D3DFVF_NORMAL)//灵活顶点格式
3. struct CUSTOMVERTEX 
4. {
5.     D3DXVECTOR3 position;
6.     D3DXVECTOR3 normal;//添加法线
7. };

 

（2）修改顶点数据：

1.     vertices[0].position = D3DXVECTOR3(-1.0f,-1.0f, 0.0f);//四个点
2.     vertices[0].normal   = D3DXVECTOR3(-1.0f,-1.0f, -2.0f); 
3.     vertices[2].position = D3DXVECTOR3( 1.0f,-1.0f, 0.0f);
4.     vertices[0].normal   = D3DXVECTOR3(-1.0f,-1.0f, -2.0f); 
5.     vertices[1].position = D3DXVECTOR3( 1.0f, 1.0f, 0.0f);
6.     vertices[0].normal   = D3DXVECTOR3(-1.0f,-1.0f, -2.0f); 

（3）添加灯光

1.     D3DLIGHT9 d3dlight;
2.     ZeroMemory(&d3dlight, sizeof(D3DLIGHT9));
3.     d3dlight.Type = D3DLIGHT_DIRECTIONAL;//平行光
4.     d3dlight.Direction = D3DXVECTOR3(0.0f, 0.0f, 1.0f);
5.     d3dlight.Diffuse.r = 1.0f;
6.     d3dlight.Diffuse.g = 1.0f;
7.     d3dlight.Diffuse.b = 0.0f;
8.     d3dlight.Range     = 1000.0f;
9.     g_pD3DDev->SetLight(0, &d3dlight);
10.     g_pD3DDev->LightEnable(0, true);

 

现在三角形又是另外一种颜色了
