I did this little project as part of a uni homework, and I gotta admit, voxels are some interesting technology.
In this demo, I'm playing with the isometric level, increasing and decreasing.
Not gonna lie, I'm not very good at this, mistakes were made, and this thing is increasing in RAM usage, going at a rate of 0.5Gb every 20 seconds ish.
Cool guys on Hive:
