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);
另外，还可以使用D3DXCreateFont函数创建ID3DXFont的对象。
