OpenGL显示中文函数

void glDrawString(unsigned char *str)

{

GLYPHMETRICSFLOAT pgmf[1];

HDC hDC=wglGetCurrentDC();

HFONT hFont;

LOGFONT lf ;

memset(&lf,0,sizeof(LOGFONT));

lf.lfHeight = 1 ;

lf.lfWidth = 0 ;

lf.lfEscapement = 0 ;

lf.lfOrientation = 0 ;

lf.lfWeight = FW_NORMAL ;

lf.lfItalic = FALSE ;

lf.lfUnderline = FALSE ;

lf.lfStrikeOut = FALSE ;

lf.lfCharSet = GB2312_CHARSET ;

lf.lfOutPrecision = OUT_TT_PRECIS ;

lf.lfClipPrecision= CLIP_DEFAULT_PRECIS ;

lf.lfQuality = PROOF_QUALITY ;

lf.lfPitchAndFamily = VARIABLE_PITCH | TMPF_TRUETYPE | FF_MODERN ;

lstrcpy (lf.lfFaceName, "宋体") ;

hFont = CreateFontIndirect(&lf);

//设置当前字体

SelectObject(wglGetCurrentDC(),hFont);

DWORD dwChar;

int ListNum;

for(size_t i=0;i<strlen((char *)str);i++)

{

if(IsDBCSLeadByte(str[i]))

{

dwChar=(DWORD)((str[i]<<8)|str[i+1]);

i++;

}

else

dwChar=str[i];

ListNum=glGenLists(1);

wglUseFontOutlines(hDC,dwChar,1,ListNum,0.0,0.1f,WGL_FONT_POLYGONS,pgmf);

glCallList(ListNum);

glDeleteLists(ListNum,1);

}

使用

byte cstr[]={"中文测试"};

glDrawString(cstr);
