從setting -> compiler 取消C++11 即可編譯

打光Lighting

在main裡面glutMainloop();前加入程式碼

    glEnable(GL_LIGHTING);

    glEnable(GL_DEPTH_TEST);

    glEnable(GL_LIGHT0);

    glLightfv(GL_LIGHT0, GL_POSITION, pos);

並在main之前加上

    GLfloat pos[]={0.0,0.0,-1.0,0.0};

編譯執行結果

加入Keyboard,Mouse

#include<stdio.h>

int rotateX=0,rotateY=0,rotateZ=0;

void keyboard(unsigned char key,int x,int y)

{

printf("now: %c (%d %d)\n",key,x,y);

}

在main中加入

glutMouseFunc(mouse);

glutKeyboardFunc(keyboard);

編譯執行結果

在void keyboard();中加入

if(key=='1')rotateX++;

if(key=='2')rotateY++;

if(key=='3')rotateZ++;

glutPostRedisplay();

加上

void mouse(int button,int state,int x,int y)

{

    printf("button:%d state:%d (%d %d)\n",button,state,x,y);

}

在display();中加入

glPushMatrix();

    glRotatef(rotateX,1,0,0);

    glRotatef(rotateY,0,1,0);

    drawmodel();

glPopMatrix();

即可用按鍵1,2,3對x,y,z軸做即時旋轉

Mouse motion

在mouse();中加入

    if(state==GLUT_DOWN)

    {

        oldX=x;

        oldY=y;

    }

加入函式

void motion(int x,int y)

{

    rotateY+= -(x-oldX);

    rotateX+= -(y-oldY);

    oldX=x;

    oldY=y;

    glutPostRedisplay();

}

在main中加入

glutMotionFunc(motion);
