为什么 D3DXCreateCylinder 制作的网格着色/材质不起作用？

This question is in continuation of "why D3DXCreateCylinder is not creating a cylinder? https://stackoverflow.com/questions/5583646/why-d3dxcreatecylinder-is-not-creating-a-cylinder". I m able to draw the cylinder but it is only drawing it as .

代码如下

void draw_Cylinder(void){

    D3DXMATRIX rot_matrix;
    D3DXMATRIX trans_matrix;
    D3DXMATRIX world_matrix;
    static float rot_triangle=0.0f;
    static float rot_triangle2=0.0f;


    D3DXMatrixRotationY(&rot_matrix,rot_triangle);  //Rotate the cylinder
    D3DXMatrixRotationX(&rot_matrix,rot_triangle2);  //Rotate the cylinder
    D3DXMatrixTranslation(&trans_matrix,2.0f,0,20.0f); //Shift it 2 units to the left
    D3DXMatrixMultiply(&world_matrix,&rot_matrix,&trans_matrix);



    D3DMATERIAL9  material;// = new D3DMATERIAL9();



    ZeroMemory( &material, sizeof(D3DMATERIAL9) );

    // Set the RGBA for diffuse reflection.
    material.Diffuse.r = 0.5f;
    material.Diffuse.g = 0.0f;
    material.Diffuse.b = 0.5f;
    material.Diffuse.a = 1.0f;

    // Set the RGBA for ambient reflection.
    material.Ambient.r = 0.5f;
    material.Ambient.g = 0.0f;
    material.Ambient.b = 0.5f;
    material.Ambient.a = 1.0f;

    // Set the color and sharpness of specular highlights.
    material.Specular.r = 1.0f;
    material.Specular.g = 1.0f;
    material.Specular.b = 1.0f;
    material.Specular.a = 1.0f;
    material.Power = 2.0f;

    // Set the RGBA for emissive color.
    material.Emissive.r = 0.0f;
    material.Emissive.g = 0.0f;
    material.Emissive.b = 0.0f;
    material.Emissive.a = 0.0f;


    g_d3d_device->SetMaterial(&material);

    g_d3d_device->SetTexture(0,NULL);

    g_d3d_device->SetTransform(D3DTS_WORLD,&world_matrix);
    m_ppMeshCylinder->DrawSubset(0);
    ////Render from our Vertex Buffer
    //g_d3d_device->DrawPrimitive(D3DPT_TRIANGLELIST, //PrimitiveType
    //                            0,                  //StartVertex
    //                            g_pyramid_count);   //PrimitiveCount

    rot_triangle+=0.0007f;
    if(rot_triangle > D3DX_PI*2)
    {  
        rot_triangle-=D3DX_PI*2;
    }

    rot_triangle2+=0.0007f;
    if(rot_triangle2 > D3DX_PI*2)
    {  
        rot_triangle2-=D3DX_PI*2;
    }
}

或下载项目。 我在这里吸引了我的代码”” 我想用 3D 阴影来绘制它，如果默认渲染的话，通常任何 3D 网格都会有这种阴影。 我对材料不太了解。或者是显卡的问题（我只是想：D）。

另外我在哪里可以获得abt的信息和样品SetRenderState

Try

g_d3d_device->SetRenderState( D3DRS_DIFFUSEMATERIALSOURCE, D3DMCS_MATERIAL );

目前，它默认使用“颜色 1”，这是 2 种可能的顶点颜色中的第一种。
