Really cool project! The only thing I noticed is that the performance feels a bit slow at times, and it could use a little more fluidity, especially when interacting with the model.
Other than that, everything feels really well done. Building something like this in JavaScript/HTML, especially with a 3D model this detailed, must be quite challenging from an optimization standpoint.
Great work!
Thank you!! I was also hitting performance issues, especially on mobile - I think the latest version has gotten it a bit closer to a smoother experience, but there is still a lot of low-hanging fruit on making this more fluid (especially the step transitions).
