陳泱竹 Week06

1.開啟Lighting 打光:
從老師給的Week05範例中新增以下打光程式碼:
GLfloat pos[] = { 0.0, 0.0, -1.0, 0.0 };///

glEnable(GL_LIGHTING);///開啟打光
glEnable(GL_LIGHT0);///
glLightfv(GL_LIGHT0, GL_POSITION, pos);///
glEnable(GL_DEPTH_TEST);///

2.用滑鼠跟鍵盤控制:

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

{

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

    if(key=='1')rotateX++;

    if(key=='2')rotateY++;

    if(key=='3')rotateZ++;

    glutPostRedisplay();//立即更新畫面

}

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

{

if(state==GLUT_DOWN)

    {

        old_X=x;

        old_Y=y;

    }

}

void motion(int x,int y)

{

    rotateY += -(x-old_X);

    rotateX += -(y-old_Y);

    old_X=x;

    old_Y=y;

    glutPostRedisplay();

}

glutMouseFunc(mouse);

glutKeyboardFunc(keyboard);

配合旋轉

glRotated(rotateX,1,0,0);

glRotated(rotatey,0,1,0);

glRotated(rotatez,0,0,1);
