is that an example from the nft branch of artoolkit?
https://github.com/artoolkit/jsartoolkit5/tree/nft/examples
https://github.com/artoolkit/jsartoolkit5/blob/nft/examples/nft_threejs.html

if so, can you share the example code? then I can test it in here and tell you how it goes,
I'm very interested to get nft working so maybe we can all work together to optimize it

@Lucreitus can you be more specific? What html contains your NFT example code?

[yannklein]

@javismiles @Lucreitus the NFT working example seem to have disappeared so I recreated in the below repo:
https://github.com/YannKlein/NFT_test

@YannKlein i get a 404 page with that link, do you moved the repo in another location?

[yannklein]

Hi @kalwalt somehow my repo became private (because of github policy change?). Anyway, you should be able to access it now!
And here is the running code, if I’m not mistaken: https://yannklein.github.io/NFT_test/nft_threejs.html

[kalwalt]

thank you @YannKlein i see it now! i think that it is related to the example in jsartooolkit5 https://github.com/artoolkit/jsartoolkit5/blob/nft/examples/nft_threejs.html
and also the artoolkitx repo (more updated):
https://github.com/artoolkitx/jsartoolkit5/blob/nft/examples/nft_threejs.html
unfortunately the nft branch in each of these repo don't receive any update.
I would like to improve it but it's no so easy...

[yannklein]

@kalwalt same here! Let’s give it a try :)

[kalwalt]

@YannKlein i'm working on jsartoolkit5 -> artoolkitx because most updated, i created this issue.
If you are interested we can continue to discuss there, Also because is more related to jsartoolkit5 than AR.js

The example is working ,but FPS is too slow any good news ?

[kalwalt]

@jamess922 any good news... i hadn't the time to look deeper, Sorry!

I get the same problem, I use the iPhone X 64GB. But it still very very slow.
has any good news?

[kalwalt]

@breezeLoganGithub no any news, but maybe it will be an emscripten version of ArtoolkitX, it should integrate NFT see this issue https://github.com/artoolkitx/artoolkitx/issues/83
