機器人鏡頭轉動

float eyeX=0.3,eyeY=0.2,eyeZ=0.4,objX=0,objY=0,objZ=0,upX=0,upY=1,upZ=0;

gluLookAt(eyeX,eyeY,eyeZ,objX,objY,objZ,upX,upY,upZ);

加入空白鍵

轉換鏡頭

機器人會螺旋旋轉

如果把key='o'裡面的程式打在main裡(glutMainLoop();之上)

一開始就不需再按o了  !!

變顏色邊旋轉

如果要固定某些顏色者要再亂數前打"100+"

變顏色邊旋轉  再放大

float color=0;

void timerRotateShow(int t)

{

if(t%2==0) glClearColor((rand()%255)/255.0,(rand()%255)/255.0,(rand()%255)/255.0,(rand()%255)/255.0);

glutTimerFunc(30,timerRotateShow,t+1);

eyeX=cos(t/100.0*3.1415);

eyeZ=sin(t/100.0*3.1415);

eyeY-=0.005;

theSize+=0.01;

glutPostRedisplay();

}
