if the file is already in your web project you should add a relative path here like /include/gs_...

oh ok and no prefix before /include, right

Oh perfect it works, my last question will be about the performance, how can I improve the performance as I am getting like 2-5 FPS on my web browser for the GS as it is also 158 MB

Gaussian splats are quite performance heavy. You can reduce the amount of splats but same as our sample you shouldn't expect it to run for example on Quest and so on.

@devout bluff might give you more advice how to optimize your splat map.

Otherwise, one thing you could do is to hide the bad performance, reduce motion and allow for very slow rotation. Alternatively you could predefine just certain views and cross fade between them with a HTML overlay / CSS filter.

Also you can adjust the render scale.

There are ongoing efforts to improve file size and performance for gaussian splats in the community, and you could e.g. switch from our splat renderer to the one Luma is providing with their tooling, which I believe is more optimized on mobile by now.

Generally approx. 1 million splats should work "ok" on mobile devices, not on VR devices though. If your number is higher then you can expect worse perf on mobile.
