2、練習使用GDI函數(shù)顯示圖像

glutInit(

glutInitDisplayMode(GLUT_SINGLE|GLUT_RGB);

glutInitWindowSize(1000,1000);

glutInitWindowPosition(0,0);

glutCreateWindow("實驗一");

glutDisplayFunc(

glutMainLoop();

}

茶壺

voiddisplay(void)

{

glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

glColor3f(0.0,1.0,0.0);//綠色繪制

glEnable(GL_DEPTH_TEST);//深度緩沖區(qū)

glutWireTeapot(2);//繪制茶壺

glFlush();

glutSwapBuffers();

}

voidreshape(intw,inth)

{

glViewport(0,0,w,h);//設(shè)置視口

glMatrixMode(GL_PROJECTION);//將當前矩陣指定為投影模式glLoadIdentity();

gluPerspective(60,(GLfloat)w/(GLfloat)h,1.0,20);//創(chuàng)建透視投影矩陣glMatrixMode(GL_MODELVIEW);

glLoadIdentity();

gluLookAt(0,5,5,0,0,0,0,1,0);//觀測點

}

球

voiddisplay(void)

{

glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

glColor3f(0.0,1.0,0.0);//綠色繪制

glEnable(GL_DEPTH_TEST);//深度緩沖區(qū)

glutWireSphere(1,20,16);//繪制球體

glFlush();

glutSwapBuffers();

}

voidreshape(intw,inth)

{

glViewport(0,0,w,h);//設(shè)置視口

glMatrixMode(GL_PROJECTION);//將當前矩陣指定為投影模式

glLoadIdentity();

gluPerspective(60,(GLfloat)w/(GLfloat)h,1.0,20);//創(chuàng)建透視投影矩陣glMatrixMode(GL_MODELVIEW);
