大家新年好！
刚学OpenGL，过年了，拼凑个小玩意向大家拜年！祝大家新春快乐，吉祥如意！
程序代码：
#include "windows.h"
#include "GL/glut.h"
#include "stdlib.h"
#include "stdio.h"
void myDisplay (void);
void ChangeSize (int w, int h);
void SelectFont (int size, int charset,char* face);
void myString (char* str);
void myPlay (void);
int WINAPI WinMain (HINSTANCE h1, HINSTANCE h2, LPTSTR cmdline, int cmdshow){ /* 用 "main" 用不了 SelectFont ()中的3个函数 */
int argc = 1;
char* argv[] = {"OpenGL"}; /* ? char** 报错 */
glutInit (&argc, argv); /* 初始化 */
glutInitDisplayMode (GLUT_RGB | GLUT_SINGLE);
glutInitWindowPosition (0, 0);
glutInitWindowSize (800, 600);
glutCreateWindow ("2013");
glutDisplayFunc (&myDisplay);
glutMainLoop (); }
void myDisplay (void){
glClearColor (0, 0, 0, 1);
glClear (GL_COLOR_BUFFER_BIT);
myPlay ();
glClear (GL_COLOR_BUFFER_BIT);
glColor3f (1, 0, 0);
SelectFont(72, ANSI_CHARSET, "Comic Sans MS");
glRasterPos2f (-0.3, 0);
myString ("Happy New Year");
glFlush (); }
void ChangeSize (int w, int h){
float aspectRatio = 0;
if (h == 0){
h = 1; }
glViewport (0, 0, w, h);
glMatrixMode (GL_PROJECTION);
glLoadIdentity ();
aspectRatio = (float)w / (float)h;
if (w <= h) {
glOrtho (-100, 100, -100 / aspectRatio, 100 / aspectRatio, 1, -1); }
else
glOrtho (-100 * aspectRatio, 100 * aspectRatio, -100, 100, 1, -1);
glMatrixMode (GL_MODELVIEW);
glLoadIdentity (); }
void SelectFont (int size, int charset,char* face){
HFONT hFont = CreateFontA (size, 0, 0, 0, FW_MEDIUM, 0, 0, 0, charset, OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY, DEFAULT_PITCH | FF_SWISS, face);
HFONT hOldFont = (HFONT)SelectObject (wglGetCurrentDC (), hFont);
DeleteObject (hOldFont); }
void myString (char* str){
static int isFirstCall = 1;
static GLuint lists = 0;
if (isFirstCall){
isFirstCall = 0;
lists = glGenLists (128);
wglUseFontBitmaps (wglGetCurrentDC (), 0, 128, lists); }
for (; *str != '\0'; str++){
glCallList (lists + *str); } }
void myPlay (void){
glColor3f (1, 1, 1);
glRasterPos2f (-0.3, 0);
SelectFont(48, ANSI_CHARSET, "Comic Sans MS");
myString ("Wait");
for (int i = 1; i <= 5; i++){
myString (".");
glFlush ();
Sleep (500); } }
虽然有些地方还不太明白，不过我相信，
PS：Win API 的函数名真是不漂亮...
