It's obvious Egyptians could carve granite using stone instruments. What is worth more investigation, is how they carved symmetric granite vases within 1/100th of an inch precision.
nowadays, when people need precision to 1/100th of an "inch" (250μm in modern units) on soft materials like unhardened steel, they can use steel tools
but when they need precision of 1μm or better (in medieval units, 1/25000th of an "inch"), or when they're cutting materials harder than steel, they resort to grinding with stone, typically emery (sapphire) for most of the grinding, followed by polishing. poor people who don't have steel tools also commonly do this for lower-precision work in soft materials; you can find all kinds of videos on youtube of people using angle grinders for things that a well-equipped machine shop would do with a bandsaw or milling machine
similarly, to get the dimensional references to measure to, common shop work can use cast-iron straight edges. but, for more precise work, they resort to granite surface plates
the egyptians of the old kingdom clearly had granite surface plates (they built significant parts of the pyramids' interiors out of them) and grinding, though they were evidently using the inferior quartz sand as their abrasive
as for symmetry, the most likely explanation is that they used lathes; the oldest indisputable records of lathes are from new kingdom egypt, but rotationally symmetric work that seems to have been made on a lathe appears as far back as the old kingdom
with respect to granite, while i don't doubt that you can find a granite vase here and there, most ancient egyptian fine stone carvings are from much softer rocks such as schist, alabaster (gypsum), and "alabaster" (calcite)
so i would say the investigation has already been done and found convincing answers
If you're like me and want to some actual evidence,
here's a video where they scanned and uploaded STL files from pre-dynastic Egyptian vases.

This video is really frustrating. It spends the first 10 mintues trying to convince the viewer that these vases are not fake, yet has no evidence other than "There is no possible way these are fakes, just look at them!". Then he actively offers up that they have not performed this analysis on any museum piece vase which has been confirmed to come from an Egyption tomb or pyramid.
Just a free wip wrapper but kinda interesting. It gives you RPG class skills in a visual format so you can get ideas for RPG talent trees.

Amazing job! Any specific settings in Three.js you used to get the great mobile performance? Really interested in seeing anything you'd like to share about how you optimized performance. Amazing work!
Nothing specific regarding mobile but we worked on rendering optimizations quite a bit to make the experience smooth. Most notably the render pipeline is based on MRT (Multiple Render Targets) which renders multiple frames at the same time, which is great when doing post-processing stuff. Also we made sure to keep the number of draw calls quite low by merging static objects. There is also a lot of culling going on, hiding rooms that are not visible.
We'll probably post more technical details on X in the coming days/weeks, be sure to follow us if you're interested.
https://getimg.ai/tools/api#pricing, curious if there are better options though. Do you think an option 50% cheaper than that would be easy to get attention for? Still building and testing atm, but should easily be able to provide that cheap.
This is interesting when viewed in light of the recent claim that the enclosing walls of the sphinx demonstrate water erosion before the start of the dynastic Egyptians.
It is clear that parts of the sphinx were sculpted by the dynastic Egyptians.
What is not clear is exactly how long ago human construction started to modify its appearance from a natural formation.
It would be nice to see some more evidence for the timeline of the human shaping of the structure, from the structure itself.
You type in a class idea, then you get themed skills back in a skill tree-like diagram, with flavor text for each ability.
Still many things that could be improved, just thought it was fun.
