Moving bounding box in 3D using libGDX

Question

How do I go about moving a bounding box in libGDX?

I want to make the bounding box capture my character and move with him.

So ideally I want to be able to copy my vector 3 from my model instance and set it on the bounding box.

There doesn't seem to be any method like setToTranslation() on the BoundingBox class. How am I supposed to do it?

From the documentation it looks like you have a few options.

1. Use the set method to set the min and max bounds. So, you can move the box by moving both the min and max. Something like box.set(box.min + moveAmt, box.max + moveAmt);

2. Use the mul to multiply the bounds by a matrix. Create a translation matrix to translate the bounds by your movement amount. Something like box.mul(new Matrix4(moveAmt, QuaternionIdentity, Vector3Ones).
