[SOLVED] How to split Euler angle curve between two keyframes?

[trouble3524]

We are making a tool just like Unreal Engine's Matinee Editor.

 

But We have a problem with rotation track.

 

Unity3D and Unreal Engine's rotation track can split Euler angle from a wolrd matrix(like Unreal Movement Track::Split Translate and Rotation) and build a Euler angle curve in Curve Editor.

 

just like 3ds max Graph Editor.

 

Then We have problem here,we can split Euler angle from a Object's world matrix,but build a Euler curve need more infomation between two keyframes,because the Euler change is not linear.

 

We just know two keyframes' Euler angle,It can be NOT build curve.

 

So,how to make it??

 

Thanks.

P.S.

Maybe we need to record users' operation,

Like this in Unreal Matinee Editor:

 

1.User create a movement track with a Interp Mesh

2.Create keyframe.

3.User rotate the mesh 720 degree,then release the mouse,and create the second keyframe.

 

Unreal know the user rotated the mesh 720 degree,

 

So we do not know how to record the user's operate,and we can NOT split Euler angle,build the Euler curve.

Tracker system (which is what you are implementing) will most probably be available in the next update (in about two weeks or so). It will solve most of your problems or at least be of help.
