    3D Rotation

    EljahFalling

      I am trying to rotate a symbol about the y-axis, 45 degrees one direction, then back to center, then 45 degrees the other direction.  Seems like a relatively simple task, except here is what happens.

       

      Here is the object with no rotation:

      Here is the object rotated exactly 45 degrees:

      And here is the object roatated exactly -45 degrees:

       

      right.jpg

       

       

      Anyone see a slight inconsistency here??  I need the object to rotate the same as it did the first time but in reverse, otherwise "45" and "-45" are generally worthless numbers to refer to...

       

      Is it something to do with the pivot point?  I made sure the registration point was in the center when I created the symbol.  It doesn't seem to be pivoting the object around the center though.  How do I rotate about the y-axis using a pivot point that is actually in the center and gives the same (but opposite) effect when rotating it one way versus the other?

          using actionscript you pivot about the registration point.  in the ide you're pivoting about that 3d-rotation symbol that's on your stage.

           

          because that symbol is in two different spots with your two rotations, your pivot point is changed.  to remedy, use the same pivot point.
