D3DXCreateMeshFVF

首先创建一个ID3DXMesh接口。 ID3DXMesh接口的说明可以参数龙书。

这里主要是用代码来讲解：

#define VERTEX_FVF   (D3DFVF_XYZ | D3DFVF_TEX1)hr = D3DXCreateMeshFVF(12,24,D3DXMESH_MANAGED,VERTEX_FVF,m_pd3dDevice,&pMesh);VERTEX vertices[] = {//正y面?{-5.0f, -5.0f, 0.0f, 0,1}, {-5.0f, 5.0f, 0.0f, 0,0},{5.0f, 5.0f, 0.0f,1,0}, {5.0f, -5.0f, 0.0f, 1,1},  //侧¨¤面?r{5.0f, -5.0f, 0.0f, 0,1}, {5.0f, 5.0f, 0.0f,0,0}, {5.0f, 5.0f, 10.0f,1,0}, {5.0f, -5.0f, 10.0f, 1,1}, //后¨®面?{5.0f, -5.0f, 10.0f, 0,1}, {5.0f, 5.0f, 10.0f,0,0}, {-5.0f, 5.0f, 10.0f, 1,0},{-5.0f, -5.0f, 10.0f, 1,1}, {-5.0f, -5.0f, 10.0f, 0,1},{-5.0f, 5.0f, 10.0f, 0,0},{-5.0f, 5.0f, 0.0f, 1,0}, {-5.0f, -5.0f, 0.0f, 1,1},{-5.0f, 5.0f, 0.0f, 0,1},{-5.0f, 5.0f, 10.0f, 0,0},{5.0f, 5.0f, 10.0f, 1,0},{5.0f, 5.0f, 0.0f, 1,1},/*   {-5.0f, -5.0f, 0.0f, 0,1}, {-5.0f, -5.0f, 10.0f, 0,0}, {5.0f, -5.0f, 10.0f, 1,0}, {5.0f, -5.0f, 0.0f, 1,1}*/{-5.0f, -5.0f, 0.0f, 0,1}, {5.0f, -5.0f, 0.0f, 0,0},{5.0f, -5.0f, 10.0f, 1,0}, {-5.0f, -5.0f, 10.0f, 1,1},  //底下的面。需要用逆时针。不然会被剔除};把上面的顶点数据拷贝到 网格里面void* pBuffer;pMesh->LockVertexBuffer(0,(void**)&pBuffer);memcpy(pBuffer,vertices,sizeof(vertices));pMesh->UnlockVertexBuffer();接着创建 索引数据WORD* i = 0;   pMesh->LockIndexBuffer(0, (void**)&i);   // fill in the front face index data   i[0] = 0; i[1] = 1; i[2] = 2;   i[3] = 0; i[4] = 2; i[5] = 3;   // fill in the back face index data   i[6] = 4; i[7]  = 5; i[8]  = 6;   i[9] = 4; i[10] = 6; i[11] = 7;   // fill in the top face index data   i[12] = 8; i[13] =  9; i[14] = 10;   i[15] = 8; i[16] = 10; i[17] = 11;   // fill in the bottom face index data   i[18] = 12; i[19] = 13; i[20] = 14;   i[21] = 12; i[22] = 14; i[23] = 15;   // fill in the left face index data   i[24] = 16; i[25] = 17; i[26] = 18;   i[27] = 16; i[28] = 18; i[29] = 19;   // fill in the right face index data   i[30] = 20; i[31] = 21; i[32] = 22;   i[33] = 20; i[34] = 22; i[35] = 23;   pMesh->UnlockIndexBuffer();   //下面是创建了6个集合，创建多少个接口。后面就需要绘制几个集合
DWORD* attributeEuffer = 0;pMesh->LockAttributeBuffer(0,&attributeEuffer);for ( int a = 0; a < 2; a++){attributeEuffer[a] = 0;}for ( int b = 2; b < 4; b++){attributeEuffer[b] = 1;}for ( int c = 4; c < 6; c++){attributeEuffer[c] = 2;}//优化hr = pMesh->OptimizeInplace(         D3DXMESHOPT_ATTRSORT |   D3DXMESHOPT_COMPACT  |   D3DXMESHOPT_VERTEXCACHE,   &adjacencyBuffer[0],   0, 0, 0);   for ( int c = 6; c < 8; c++){attributeEuffer[c] = 3;}for ( int c = 8; c < 10; c++){attributeEuffer[c] = 4;}for ( int c = 10; c < 12; c++){attributeEuffer[c] = 5;}pMesh->UnlockAttributeBuffer();std::vector<DWORD> adjacencyBuffer(pMesh->GetNumFaces() * 3);   pMesh->GenerateAdjacency(0.0f, &adjacencyBuffer[0]);   for(int i = 0; i < 6; i++)   { pMesh->DrawSubset( i );   }
