统一线性插值和球面线性插值不动的顺利

Question

我创建了一个协程来处理我的相机移动和方向看，在这种协程，我有：

public IEnumerator MoveCameraLookAtObject(Transform _cameraTransform, Vector3 startPos, Vector3 endPos, Vector3 lookAt, float time) 
{ 
    // Loop through a timed based situation. 
    for (float i = 0f; i <= 1.0f; i += Time.deltaTime/time) 
    { 
     // Lerp the Movement. 
     _cameraTransform.position = Vector3.Lerp(startPos, endPos, i); 
     // Slerp the rotation. 
     Vector3 relativePos = lookAt - _cameraTransform.position; 
     Quaternion rotation = Quaternion.LookRotation(relativePos); 
     _cameraTransform.rotation = Quaternion.Slerp(_cameraTransform.rotation, rotation, i); 
     } 
     yield return null; 
    } 
} 

的问题是，当我真正感到Lerping和Slerping它看起来可怕并且不流畅的东西。我很困惑我做错了什么，因为我花了好几天的时间来想清楚这一点。我看着Lerp and Slerp Question，看到这几乎是同样的问题，但人们需要我已经有了答案。

这将是更多的东西像这样

public IEnumerator MoveCameraLookAtObject(
    Transform _cameraTransform, 
    Vector3 startPos, Vector3 endPos, Vector3 lookAt, float time) 
{ 
float totalTime = 1.25f; // or whatever 

float startTime = Time.time; 
float endTime = startTime + totalTime; 

startPos = etc etc 
endPos = etc etc 

startROTATION = ... 
endROTATION = ... 
// calculate those ONLY OUT HERE!!! not in the loop 

while (Time.time < endTime) 
    { 
    float timeSoFar = Time.time - startTime; 
    float fractionTime = timeSoFar/totalTime; 

    //do NOT USE underscores in variable names 
    cameraTransform.position = 
    Vector3.Lerp(startPos, endPos, fractionTime); 

    cameraTransform.rotation = 
    Quaternion.Slerp(startROTATION, endROTATION, fractionTime); 
    yield return null; // this goes IN HERE 
    } 
} 

在与JUST lerping的位置的第一测试，然后尝试扭曲！干杯
