skyline开发中Yaw，Picth，Roll等值意义和设置问题

Yaw, Pitch and Roll Angles

The Yaw (direction), Pitch (tilt) and roll values for the camera, plane and objects are defined as described in the following diagram.

 Yaw values

Range from 0 to 360 where 0=North, 90=East, 180=South and 270=West. TerraExplorer Pro adjusts illegal values to this range by modulating the illegal number.

  Pitch values

Range from -90 to +90 where 0 = Horizon, +90 = straight up and –90 = straight down. TerraExplorer Pro adjusts illegal values to this range by modulating the illegal number.

  Roll values

Range from -90 to +90 where 0 = Horizon, +90 = Full roll right and –90 = Full roll left. TerraExplorer Pro adjusts illegal values to this range by modulating the illegal number.

 

 

假设存在一个点A。

当Yaw=0表示从正南往正北看该点，Yaw=90表示从正东往正西看该点，以此类推，值范围（0至360）。

当Pitch =0表示水平看改点，Pitch =45表示从下往上45度仰视看改点，Pitch =-45表示从上往下45度俯视改点，以此类推，值范围（-90至90）。
