光照示例
技巧如下：
在设置可变顶点格式时加入法线和漫反色，如下所示：
开启光照和Z缓存：
设置光源属性并打开光源：
完整源码如下：
效果图：
在设置可变顶点格式时加入法线和漫反色，如下所示：
// The 3D vertex format and descriptor
typedef struct
{
float x, y, z; // 3D coordinates
float nx, ny, nz; // normals
D3DCOLOR diffuse; // color
} VERTEX;
#define VERTEX_FVF (D3DFVF_XYZ | D3DFVF_NORMAL | D3DFVF_DIFFUSE)
typedef struct
{
float x, y, z; // 3D coordinates
float nx, ny, nz; // normals
D3DCOLOR diffuse; // color
} VERTEX;
#define VERTEX_FVF (D3DFVF_XYZ | D3DFVF_NORMAL | D3DFVF_DIFFUSE)
开启光照和Z缓存：
// enable d3d lighting
g_d3d_device->SetRenderState(D3DRS_LIGHTING, TRUE);
// enable z-buffer
g_d3d_device->SetRenderState(D3DRS_ZENABLE, D3DZB_TRUE);
g_d3d_device->SetRenderState(D3DRS_LIGHTING, TRUE);
// enable z-buffer
g_d3d_device->SetRenderState(D3DRS_ZENABLE, D3DZB_TRUE);
设置光源属性并打开光源：
D3DLIGHT9 light;
// set light data, color, position, range.
ZeroMemory(&light, sizeof(light));
light.Type = D3DLIGHT_POINT;
light.Diffuse.r = light.Ambient.r = 0.5;
light.Diffuse.g = light.Ambient.g = 0.5;
light.Diffuse.b = light.Ambient.b = 0.0;

light.Attenuation0 = 0.5;
light.Position.x = 300.0;

// set and enable the light
g_d3d_device->SetLight(0, &light);
g_d3d_device->LightEnable(0, TRUE);
// set light data, color, position, range.
ZeroMemory(&light, sizeof(light));
light.Type = D3DLIGHT_POINT;
light.Diffuse.r = light.Ambient.r = 0.5;
light.Diffuse.g = light.Ambient.g = 0.5;
light.Diffuse.b = light.Ambient.b = 0.0;
light.Diffuse.a = light.Ambient.a = 1.0;
light.Range = 1000.0;
light.Attenuation0 = 0.5;
light.Position.x = 300.0;
light.Position.y = 0.0;
light.Position.z = -600.0;
// set and enable the light
g_d3d_device->SetLight(0, &light);
g_d3d_device->LightEnable(0, TRUE);
