Can I run around with my phone, and capture some Gaussian Splats of... grass... bushes... dirt...

And then select one-meter square patches of land... and one-meter cubes of spots with bushes...

And then make a "Minecraft-looking" world, repeating the grass block all over the place, with occasional dirt and bushes?

I'm guessing I'd need some pretty beefy hardware to render thousands of blocks...
