Models Shaking Fix

Question

Hello everyone,

Extremely simplistic models are shaking a lot in Easy AR. It has been a while, and Easy AR has not addressed this problem yet. In this forum, you stated that you would write a thorough tutorial in September, 2017l:

https://forum.easyar.com/portal.php?mod=view&aid=16

I found a few posts, but they are not useful much, as authors do not explain anything in details.

If you guys have a solution to this problem, please share it here.

Easy AR, please, either fix this jittery models issue, or at least write a tutorial on how to do it.

Thanks.

Can you send your image to us?

I second this. My models are shaking a lot as well. I tried setting the ARCamera to Specific or Camera. Didn't work. I used the code here in https://blog.csdn.net/an050602/article/details/69597746 as well in my ImageTargetBehavior. Didn't work.

The problem of image itself needs to be eliminated first.  Can you show us  your image ?

I already sent you the image in the other thread. Here it is again: https://imgur.com/a/zyxGUti

Answer 2

I'm using EasyAr 3.0 with Unity, and I found that adding this smoothing function to the ImageTargetController's OnTracking() function works pretty well. In my case, I actually am inheriting from the class and overriding the function, so it looks something like this:

public override void OnTracking(Matrix4x4 pose)
    {
        base.OnTracking(pose);

        // Rotation Smoothing
        const float smoothingSpeed = 30.0f;
        float timeFactor = Quaternion.Angle(lastRotation, this.transform.rotation) * smoothingSpeed * Time.deltaTime;
        lastRotation = Quaternion.RotateTowards(lastRotation, this.transform.rotation, timeFactor);
        this.transform.rotation = lastRotation;
    }
