DirectX学习笔记（十）：3D字体的实现及用ID3DXFont接口绘制文本
ID3DXFont接口介绍：
D3DX库提供了ID3DXFont 接口，该接口用于在Direct3D应用程序中绘制文本。这个接口的使用，有优点，也有缺点。缺点就是在接口的内部使用了GDI图形设备接口，导致了该接口在性能上会有稍微的损失。优点就是由于在接口的内部使用了GDI图形设备接口，导致了它能够处理一些复杂的字体和格式。
1.如何使用ID3DXFont接口绘制文本信息
第一步：创建一个ID3DXFont对象：
//字体接口
ID3DXFont* Font = 0;第二步：填充D3DXFONT_DESC结构
在创建完毕后，我们需要对索要使用的字体进行描述，那么这个时候就需要用到D3DXFONT_DESC结构。该结构的参数如下
typedef struct D3DXFONT_DESC {
INT Height;//Height, in logical units,指的是字体的高度，
UINT Width;//Width, in logical units
UINT Weight;//Weight of the font in the range from 0 through 1000.
UINT MipLevels;//文本的Miplevels
BOOL Italic;//是否斜体
BYTE CharSet;//字符集
BYTE OutputPrecision;// 指定Windows与期望字体大小的匹配方法
BYTE Quality;//输出质量
BYTE PitchAndFamily;//斜度和family索引
TCHAR FaceName;//字体类型名称
} D3DXFONT_DESC, *LPD3DXFONT_DESC;那么我们这样填充：
D3DXFONT_DESC df;
ZeroMemory(&df, sizeof(D3DXFONT_DESC));
df.Height = 25;
df.Width = 12;
df.MipLevels = D3DX_DEFAULT;
df.Italic = false;
df.CharSet = DEFAULT_CHARSET;
df.OutputPrecision = 0;
df.Quality = 0;
df.PitchAndFamily = 0;
strcpy_s(df.FaceName, "TIME NEW ROMAN");第三部：填充完绘制：
如果我们获取到了ID3DXFont接口的指针，就只需要调用ID3DXFont::DrawText即可完成文本的绘制：函数参数如下：
INT DrawText(
[in] LPD3DXSPRITE pSprite,//用来绘制文字的sprite对象
[in] LPCTSTR pString,//指向字符串的指针
[in] INT Count,//字数.假如字符是以null结束的字符串则可将其指定为-1
[in] LPRECT pRect,//指向一个RECT结构，它定义一个文字被绘制在屏幕上的范围。
[in] DWORD Format,//可选参数，指定文字怎样被格式化,具体可以查sdk文档
[in] D3DCOLOR Color//文字的颜色
);我们就这样指定：
Font->DrawTextA(NULL, "Hello World", -1,&rect, DT_TOP | DT_LEFT, 0xff000000);
以上就完成了。

那么如何创建3D字体呢？
创建3D字体：
第一步：创建一个Mesh结构用来保存我们的3D文本数据：
ID3DXMesh * Text = 0;
第二步：填充LOGFONT结构
如上一样填充字体存储的结构，但是这里我们填充的是LOGFONT结构：
老版本的DirectX使用LOGFONT作为参数创建字体，在DirectX9.0c以及以后的版本里面改为使用D3DXFONT_DESC作为参数创建字体。这两个结构体大体是相同的。
下面分别列举一个使用D3DXFONT_DESC和LOGFONT作为参数的例子：
使用这个函数时，需要一个D3DXFONT_DESC结构：
D3DXFONT_DESC d3dFont;
memset(&d3dFont,0,sizeof(d3dFont));
d3dFont.Height=25; // in logical units
d3dFont.Width=12; // in logical units
d3dFont.Weight=500;// boldness, range 0(light) - 1000(bold)
d3dFont.Italic=FALSE;
d3dFont.CharSet=DEFAULT_CHARSET;
strcpy(d3dFont.FaceName,"Times New Roman");
ID3DXFont* font=0;
D3DXCreateFontIndirect(Device,&d3dFont,&font);
如果你使用的是LOGFONT结构，则：
LOGFONT lf;
ZeroMemory(&lf, sizeof(LOGFONT));
lf.lfHeight = 25; // in logical units
lf.lfWidth = 12; // in logical units
lf.lfWeight = 500; // boldness, range 0(light) - 1000(bold)
lf.lfItalic = false;
lf.lfUnderline = false;
lf.lfStrikeOut = false;
lf.lfCharSet = DEFAULT_CHARSET;
strcpy(lf.lfFaceName, "Times New Roman"); // font style
ID3DXFont* font = 0;
D3DXCreateFontIndirect(Device, &lf, &font);
我们可以这样填充：
HDC hdc = CreateCompatibleDC(0);
HFONT hFont;
HFONT hFontOld;
LOGFONT lf;
ZeroMemory(&lf, sizeof(LOGFONT));
lf.lfHeight = 25; // in logical units
lf.lfWidth = 12; // in logical units
lf.lfEscapement = 0;
lf.lfOrientation = 0;
lf.lfWeight = 500; // boldness, range 0(light) - 1000(bold)
lf.lfItalic = false;
lf.lfUnderline = false;
lf.lfStrikeOut = false;
lf.lfCharSet = DEFAULT_CHARSET;
lf.lfOutPrecision = 0;
lf.lfClipPrecision = 0;
lf.lfQuality = 0;
lf.lfPitchAndFamily = 0;
strcpy_s(lf.lfFaceName, "Times New Roman"); // font style
hFont = CreateFontIndirect(&lf);
hFontOld = (HFONT)SelectObject(hdc, hFont);
第三步：D3DXCreateText函数调用
在D3D中，自带了一个函数：D3DXCreateText函数，就是用此函数来创建3D文本：
D3DXCreateText函数参数如下：
HRESULT D3DXCreateText(
LPDIRECT3DDEVICE8 pDevice,//与网格相关的设备
HDC hDC, //一个环境句柄
LPCTSTR pText, //只想所要生成的文本字符串指针
FLOAT Deviation, //TureType字体轮廓的最大弦偏差。
FLOAT Extrusion, //Z、轴负方向度量的字体深度
LPD3DXMESH* ppMesh, //返回所创建的网格
LPD3DXMESH* ppAdjacency, //返回所创建的网格的邻接信息
LPGLYPHMETRICSFLOAT pGlyphMetrics
);
