People complaining that it's a small area, lol my man, this is fucking insane, i know AI is starting to get normalized, but they converted an image into a 3d world! even if its 1ft/1ft its still amazing.
We recently added an environment creator for our VR game which does kinda a similar thing but for even less freedom of movement, so I think I have a little bit of insight into it.
After seeing what they are showing on their page I am majorly impressed and don't feel they are misleading anyone at all
The prompting is done from the browser and it's then automatically added in the game so the next time you do your workout it is already there to select.
You are the maintainer of A-Frame? That's awesome.
We used GodotEngine in the past when it was still called VRWorkout but had to switch to Unity due to business reasons.
The environment creator uses several off the shelf models under the hood with custom loras and blender at the end to create the exportable meshes.
Users usually need to workout in the game to achieve coins to generate environments because we have no actual monetization behind it, so we can't have people generate endless amounts of environments, but if you want to try it out send me a message at michael -at- xrworkout.io and I'll set you up so you can try it.
