複製程式碼

glBegin(GL_TRIANGLES);

        glColor3f(1.0f, 0.0f, 0.0f);   glVertex2f(0.0f,   1.0f);

        glColor3f(0.0f, 1.0f, 0.0f);   glVertex2f(0.87f,  -0.5f);

        glColor3f(0.0f, 0.0f, 1.0f);   glVertex2f(-0.87f, -0.5f);

glEnd();

留下精華

程式碼: 

#include<GL/freeglut.h>

static void display(void)

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    

    glutSwapBuffers();

}

int main(int argc, char *argv[])

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("GLUT Shapes");

    glutDisplayFunc(display);

    glutMainLoop();

}

(1) 設定GLUT的初始化

(2)顯示模式

(3)開GLUT視窗

(4)顯示的函示

(5)GLUT主要的迴圈，卡住不要結束

畫茶壺

程式碼:

#include<GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("08160103 我是大美女");

    glutDisplayFunc(display);

    glutMainLoop();

}

程式碼:

#include<stdio.h>

int main(int argc,char**argv)

{

    printf("現在的argc是:%d\n",argc);

    for(int i=0;i<argc;i++){

        printf("argv[%d]是:%s\n",i,argv[i]);

    }
