So at this point, I agree that manipulating the sqlite file may be volatile, so I've shifted my focus to just modifying the map node and map generation to be ported to a GPU implementation, I just wish I could figure out the key class and method I need to focus on, because all of it seems to be rele...

asdf7389, dont try to generate a full Minetest map at once. No really, don't. The SQLITE map file can only go upto 4GB and the file becomes unstable, not to mention that the file size will grow to about 14TB. Good Luck. Hmm...I thought there was a built in limit for the max size of a map file that ...

Well finding time to work on this, I've decided to see about generating a map that hits the max size in a square fashion. Looking through to see if initial generation can be stretched to accommodate generation of the entire map at once.

Why not OpenCL? CUDA is NVIDIA-only and it's a PITA to set it up on Linux. Is there really any noticeable performance improvement by using the GPU for map generation? I bet the gains would be small since it's fast enough already. Feel free to make this just for fun, though. :) Well it's in CUDA bec...

I was imagining making a file outside of Minetest to generate a world then dump it back into Minetest to explore, but I still don't fully understand how mapgen outputs it's initial file. Still just pouring through source code and beating wolves back with a stick.

Minetest map generation using GPU

So currently I'm working on using CUDA to parallel map generation on minetest for my senior project. I'm fairly new to parallel programming, as well as C++ so it's been quite a challenge so far. I'm looking at the mapgen files and comparing to the process of how it runs when a users clicks the creat...
