Question: How to make generated splat models open with correct frontal face orientation by default?

[721125]

Hi there,First of all, thank you so much for open-sourcing this amazing work!

I have a question about the default orientation of the exported models:
When I export the generated .splat/.ply file and open it with the antimatter15's WebGL Splat Viewer (the same viewer you used on your official project page), the model always loads with an incorrect default orientation (e.g. showing the back of the head, or a tilted angle), and I have to manually rotate the camera to get the frontal face view.

However, I noticed that on your project homepage, every "Open Interactive Viewer" link loads the model with a perfect frontal face orientation by default, with no manual adjustment needed.

Could you please share some details:

1. Did you pre-process the models to fix the orientation before putting them on the page?
2. Or did you modify the viewer code to automatically set the camera to the frontal face position on model load?
3. Is there a general way to batch process all generated models, to ensure they load with the correct frontal face orientation by default?

Thank you again for your great work and your time! I really appreciate your help.

Hi, I modified the index.html file to adjust the face orientation. You can file the file here: https://github.com/weijielyu/FaceLift/blob/website/splat/index.html.
