原标题:Accelerometer Values from Android/iPhone device

我试图用一种刺.装置把我的运动描绘成一个开放的GL场面。

I ve记录了简单移动的加速计值: 接通电话(表格上打平) 10cm 前线(+x),然后是10cm后向(x)。

问题是,在计算速度和位置时,这种数值只能推进开诚布公的ube。 记录下来的消极加速度等,不足以降低速度和改变其流动。

问题是什么?

我的职责是,每当新数据出现时,更新速度和位置:

void updatePosition(double T2) {
    double T = 0.005;
    Vec3 old_pos = position.clone(), old_vel = velocity.clone();

    velocity = old_vel.plus(acceleration.times(T));
    position = old_pos.plus(old_vel.times(T).plus(acceleration.times(0.5 * Math.pow(T, 2))));

}

这是整个被俘时间的X,Y,Z 速计值:

问题回答

你们的职能是用我假设的参数T2,加速输入? 但是,你正在使用你宣布为“T=0.005”两倍的T;因此,你的职能将始终以静态的速度向前推进。
