Non-centered models can cause problems.

You can find some questions and answers to this problem.

It would sometimes be better if you could load a non-centered model with a tool and then export it centered.

Is there a tool in order to center a gltf model?

I couldn’t find anything. :face_with_monocle:

There is not always a well-defined definition of “centering.” Sometimes you want the center of the model to be at 0,0,0. Sometimes you want the model to be sitting exactly on top of the point 0,0,0, like a chair when the ground is at y=0.

Code for computing the bounding box of an object and then moving it around is not too complicated, see https://github.com/donmccurdy/three-gltf-viewer/blob/9ef59abc24fbff84a5f0ce4413ca54a31ef11957/src/viewer.js#L266-L274 for an example.

For a general-purpose tool, I would open the file in Blender, move it, and export the result.

Thanks for the information. :slightly_smiling_face:

I have already tried the calculation of the movement and rotation myself.

Since I’m not interested in modelling myself, I take finished models. When there is time, I have to take a closer look at Blender.
