On 2D-Scene,I can simply use the change in vertical and horizontal position when mouse movement to rotate and translate any object.
But on 3D-Scene,there are some problems occured.
- If object is rotated until the x-y plane(default plane) is replaced by the y-z one,then I try to translate object along the horizontal axis by use the horizontal position change when mouse movement. The object is moved into or out of the scene.
- Similarly problem occured when I rotated.
Have anyone to give me some agorithm or sampling code to do so.?
Thanks in advance.
