在三维应用环境中，旋转轴的准确表示是正确实现三维旋转的关键。通过将鼠标位置的

二维变化转换为一个辅助坐标系中的三雏旋转轴和旋转角度，进一步得到了该轴在世界坐标系下的

表示，并采用绕旋转轴反向旋转观察点的方法在OpenGL中实现了用鼠标交互式任意旋转三维场景

的功能。-In the three-dimensional environments, the axis of rotation to achieve accurate three-dimensional rotation that is the right key. By changing the mouse position is converted to an auxiliary two-dimensional coordinate system in three young rotation axis and rotation angle of the shaft further in the world coordinate system representation, and using counter-rotating around the rotation axis observation point in the method implemented in OpenGL using the mouse to rotate three-dimensional scene any interactive features.
