Dear Yohan : Thanks for your answer. I had looked through different materials about the euler angle definition and rotation matrix. but it seems it is a little bit messy since every one define their coordinate. From my understanding , under standard graphics coordinate | Y (yaw)/azimuth | | | / \ / \ / \ / \ ( Roll) Z X (pitch)/elevation | z (yaw)/azimuth | | | / \ / \ / \ / \ ( Roll) x Y (pitch)/elevation ( phomehus magnetic tracking coordinate) So whatever the coordinate look like ,the yaw should always be the rotation along vertical axis in spite it named z or Y. and so on. what is youe opinion? sorry to bother calvin __________________________________________________ Do You Yahoo!?
