I sometimes do 3D scanning of things and put them in Minecraft. From people, to objects to conversion of virtual models.
To make this useful to as many people I provide the results in several formats, packaged as a zip file.
Here is what the zip file contains:
├── Minecraft Schematics ├── Minecraft Worlds │ ├── Computer │ └── PE ├── OBJ Models │ ├── Brightened │ ├── Original │ └── Voxelized └── Voxel Files
You can find details about the contents of each directory below.
This is where you’ll find the object(s) added into “super flat” Minecraft world, ready for you to play!
I create a couple of different versions:
- Computer directory: versions for the computer version of Minecraft.
- PE directory: versions for the “Pocket Edition”- iOS and Android.
Please read our article on Installing worlds if you need help adding these to your game.
Minecraft schematics are a type of file that was developed by the Minecraft community to store parts of Minecraft worlds for reuse and sharing. MCEdit is a program that can use schematic files. You can find out more about format on the Minecraft wiki.
I also provide the scanned item as schematic files so you can re-use them in your own worlds.
These are 3D geometry files. I use the Wavefront obj format because it includes the 3D geometry as well colour texture information. The STL format is perhaps more common, but it doesn’t allow for the inclusion of colour data.
I usually provide three models, in three subdirectories:
- Original: the original 3D capture or model file
- Brightened: the same geometry as the original, but with brightened texture imagery. I need a lighter coloured version because there are very few colours (16) available in Minecraft.
- Voxelized: This is the ‘blockified’ version of the model re-converted back to a 3D geometry format. This is ready for 3D printing or other creative uses.
Minecraft represents it’s world as a large 3D grid of blocks. In computer graphics, this is often called a voxel.
But most 3D applications, including 3D scanners, produce 3D geometries - points and lines in space.
To use these models in Minecraft I have to convert from 3D geometry to voxels, and then from voxels to a schematic.
I include the intermediary voxel files in case you’d like to use them, for example with a voxel editor such as MagicaVoxel.
If you’d like to know how I create these files then please read this article.
