NeHe 系列教程之十三： 位图字体
英文教程地址：lesson13
本课将展示位图字体的创建和显示， 代码基于第一课。
首先是字休库的创建，如下所示：
namespace {#define USE_DISPLAY_LIST //使用显示列表struct FyjFont
{char *name; //字体名称int quality; //字体中的字符数量int height; //字符高度const GLubyte **characters; //字符表float xorig, yorig; //字符的原点
};//字体字符位图描述定义

};
const FyjFont fyjFont = { "-a-fyj-test-font", 256, 14, Character_Map, 0, 4 };上述代码创建了常用的Ascill码中对应的一些字母和符号。
接着是显示此字体库中的字符的一些实用方法：
/*** @param character 0~255*/
void renderCharacter(int character)
{Q_ASSERT_X(character >= 0 && character <= 255,"renderCharacter", "invalid parameter");const FyjFont *font = &fyjFont;const GLubyte *face = font->characters[character];glPushClientAttrib( GL_CLIENT_PIXEL_STORE_BIT );glPixelStorei( GL_UNPACK_SWAP_BYTES, GL_FALSE );glPixelStorei( GL_UNPACK_LSB_FIRST, GL_FALSE );glPixelStorei( GL_UNPACK_ROW_LENGTH, 0 );glPixelStorei( GL_UNPACK_SKIP_ROWS, 0 );glPixelStorei( GL_UNPACK_SKIP_PIXELS, 0 );glPixelStorei( GL_UNPACK_ALIGNMENT, 1 );glBitmap(face[ 0 ], font->height, /* The bitmap's width and height */font->xorig, font->yorig, /* The origin in the font glyph */( float )( face[ 0 ] ), 0.0, /* The raster advance -- inc. x,y */( face + 1 ) /* The packed bitmap data... */);glPopClientAttrib( );
}void renderString(const unsigned char *string)
{unsigned char c;float x = 0.0f ;const FyjFont* font = &fyjFont;glPushClientAttrib( GL_CLIENT_PIXEL_STORE_BIT );glPixelStorei( GL_UNPACK_SWAP_BYTES, GL_FALSE );glPixelStorei( GL_UNPACK_LSB_FIRST, GL_FALSE );glPixelStorei( GL_UNPACK_ROW_LENGTH, 0 );glPixelStorei( GL_UNPACK_SKIP_ROWS, 0 );glPixelStorei( GL_UNPACK_SKIP_PIXELS, 0 );glPixelStorei( GL_UNPACK_ALIGNMENT, 1 );while( ( c = *string++) )if( c == '\n' ){//画回车符时，设置宽，高为0, bitmap数据为空glBitmap ( 0, 0, 0, 0, -x, (float) -font->height, NULL );x = 0.0f;}else{const GLubyte* face = font->characters[ c ];glBitmap(face[ 0 ], font->height, /* Bitmap's width and height */font->xorig, font->yorig, /* The origin in the font glyph */( float )( face[ 0 ] ), 0.0, /* The raster advance; inc. x,y */( face + 1 ) /* The packed bitmap data... */);x += ( float )( face[ 0 ] );}glPopClientAttrib( );
}#ifdef USE_DISPLAY_LIST
//利用显示列表来重新实现上述函数
GLuint fontOffset;
void makeRasterFyjFont(void)
{GLuint i, j;glPixelStorei(GL_UNPACK_ALIGNMENT, 1);fontOffset = glGenLists(256);for (i = 0; i < 256; i++,j++) {glNewList(fontOffset + i, GL_COMPILE);renderCharacter(i);glEndList();}
}void printString(const unsigned char *s)
{glPushAttrib(GL_LIST_BIT);glListBase(fontOffset);glCallLists(strlen(reinterpret_cast<const char *>(s)), GL_UNSIGNED_BYTE, (GLubyte *)(s));glPopAttrib();
}
#endifvoid glPrint(const char *fmt, ...)
{char text[256]; // Holds Our Stringva_list ap; // Pointer To List Of Argumentsif (fmt == NULL) // If There's No Textreturn; // Do Nothingva_start(ap, fmt); // Parses The String For Variablesvsprintf(text, fmt, ap); // And Converts Symbols To Actual Numbersva_end(ap); // Results Are Stored In Text#ifdef USE_DISPLAY_LISTprintString(reinterpret_cast<unsigned char *>(text));
#elserenderString(reinterpret_cast<unsigned char *>(text));
#endif
}GLfloat cnt1; // 1st counter used to move text & for coloring.GLfloat cnt2; // 2nd counter used to move text & for coloring.
}到此为止，我们已经创建了字体，并定义了显示字库中字符的方法：
下面是初始化方法：
void MyGLWidget::initializeGL()
{glShadeModel(GL_SMOOTH); // Enables Smooth ShadingglClearColor(0.0f, 0.0f, 0.0f, 0.0f); // Black BackgroundglClearDepth(1.0f); // Depth Buffer SetupglEnable(GL_DEPTH_TEST); // Enables Depth TestingglDepthFunc(GL_LEQUAL); // The Type Of Depth Test To DoglHint(GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST); // Really Nice Perspective Calculations#ifdef USE_DISPLAY_LISTmakeRasterFyjFont();
#endif
}最后是绘制代码：
void MyGLWidget::paintGL()
{glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); // Clear The Screen And The Depth BufferglLoadIdentity(); // Reset The Current Modelview MatrixglTranslatef(0, 0, -1.0f);// Pulsing Colors Based On Text PositionglColor3f(qAbs(1.0f*((float)(cos(cnt1)))),qAbs(1.0f*((float)(sin(cnt2)))),qAbs(1.0f-0.5f*((float)(cos(cnt1+cnt2)))));// Position The Text On The ScreenglRasterPos2f(-0.45f+0.05f*float(cos(cnt1)), 0.35f*float(sin(cnt2)));// renderCharacter(97);glPrint("Active OpenGL Text With NeHe - %7.2f", cnt1);cnt1 += 0.01f;cnt2 += 0.0081f;}运行效果如下所示：
