我想添加數學來控制與陀螺儀的全景和掙扎。這是一個內置於AS3的移動應用程序。從AS3陀螺儀計算全景角的數學
我已經從陀螺儀（x和y）獲得了數據，並且獲得了當前角度（平移和傾斜）。我想要做的就是根據陀螺儀的數據以新角度更新cameraController。
我一直在試圖將我在https://github.com/fieldOfView/krpano_fovplugins/blob/master/gyro/source/gyro.source.js上找到的Javascript轉換成ActionScript3，它有點作品 - 但並不是真的。
編輯
謝謝，我想這些變化和我說相機膠捲回來，因爲歐拉的數學需要它，它運行，但也有一些是錯誤的數學。
全景似乎只是漂移和離開，過了一段時間移動電話，另一種方式它漂移，然後向右移動。
你能看到我從Javascript中丟失的重要東西嗎？

我發現怎麼別人已經在JavaScript中做了一個例子，我剛剛去如何把它轉換成AS3 https://github.com/fieldOfView/krpano_fovplugins/blob/master/不知道陀螺儀/源/ gyro.source.js – user5839
