Reading the blog post, I now know how Notch would approach building such a thing, and that he thinks his approach wouldn't really work. I still have no idea how Euclidean's implementation actually works and neither does anyone else who I've seen comment on their demo video.
The use of the word "scam" is really inaccurate based on the rest of the post. He agrees that the demo is real, and calls it a scam since others are working on similar things and they are trying to get funding. Neither others working on the same thing nor trying to get funding make something a scam. It would be a scam if they weren't really rendering what they say they are in real time, but Notch doesn't claim that.
It would be _fake_ if they weren't rendering it in real time. He didn't call it fake. He called it a scam.
The argument that it's a scam if it can't render grass blowing in the wind is ridiculous.

I think the unlimited detail refers to rendering speed, not memory requirements. The data has to be redundant to fit in memory. He also claims it runs on a laptop without GPU. So it can't be just octree or any other regular acceleration structure. So if it isn't scam, it's something new. From the author (old post on Beyond3D): "firstly the system isn’t ray tracing at all or anything like ray tracing. Ray tracing uses…
I'm fairly certain that "sorting to find the one atom for each pixel on the screen" is exactly the definition of raytracing.

He calls it a scam because they're making hyperbolic claims, very carefully ignoring any mention of any of the drawbacks to this technology, and pretending that it's all brand new technology when it's actually been done before. And they're doing this to make money via investors. It would be _fake_ if they weren't rendering it in real time. He didn't call it fake. He called it a scam.
The reddit thread http://www.reddit.com/r/gaming/comments/j6sr1/a_simple_and_e... has a bunch of good comments that outline why Notch isn't really in a position to post stuff like this.

Anyone who's watched that demo has noticed exactly what he said, that their demo is basically a 2D tilemap of a few repeated 3D objects, most likely to make the memory requirements of storing voxels at that level of detail feasible.
I am blown away by the number of people on HN and elsewhere who are posting about "how they must be doing it" and then calling it unimpressive or a technical dead end.
