Interactive previews of the car in Babylon.js, with the Khronos PBR Neutral tone mapper.

1. Uncompressed geometry + PNG textures:

2. Draco geometry compression with KTX2 texture compression:

Today the Khronos 3D Commerce working group requested two additional glTF versions, JPG and WEBP, so there would be four total glTF folders:

1. Uncompressed geometry with PNG textures.
2. Draco geometry compression with KTX2 texture compression.
3. Uncompressed geometry with JPG textures.
4. Uncompressed geometry with WEBP textures.

Then we can use these to compare size/quality tradeoffs between the files. I'll try to use the smallest compressions possible with these formats, without introducing too many artifacts.

Then I will add a section to the README along with these versions, about compression settings used, and listing the file sizes & memory sizes.

This does look really cool. And given such a model, I hesitate to ask for "more" (and of course, I have no clue whether that would even be in the budget). But... I think that animations (like "Steer" or "Open doors") could add another layer of "Woah!" here 😎

Thanks Marco!

I’m thinking of adding animations later with the interactivity extension, tap on a door to open/close it, that kind of thing.

I originally had animated doors, but with regular looping playback it gets a bit annoying after a while, so I stripped it out.

But anyone is welcome to tweak it however they like! CCBY4 is very permissive.
