Week 13
HW 1
利用 Excel 了解內插公式。
 |
HW 2
打開自己的模型。增加內插公式的函式與Timer函式。
函式：
float alpha=0.0;
float oldAngle[9]={0,0,0,0,0,0,0,0,0};
float newAngle[9]={40,40,-40,-40,0,0,0,0,0};
void interpolation()
{
for(int i=0;i<9;i++){
angle[i]=alpha*newAngle[i]+(1-alpha)*oldAngle[i];
}
alpha+=0.1;
}
void timer(int t)
{
glutTimerFunc(1000,timer,t+1);
interpolation();
glutPostRedisplay();
}
