gazprash/2d-to-3d-voxelizer

This project is a desktop tool that turns 2D pixel art into 3D voxel art. You feed it a sprite image or a sprite sheet showing several sides of a character or object, and it builds a 3D model out of it. The result can be saved as a .obj file, which is a common 3D format that works with Blender, Unity, Godot, and most other 3D or game engine software. The tool works with simple math, not AI models, to stretch a flat 2D image into a 3D voxel grid. This keeps the original art style intact, but the README is upfront that this approach has limits: it may not handle complicated pixel art with lots of varying depth very well. There are four generation modes depending on what kind of input you give it. Single mode builds a 3D shape from one image. Single Plus Repeated takes one sprite and wraps it around all four sides with an adjustable depth. Dual mode uses front and back images together. Quad mode builds a full, walk around 3D object from four images, one each for the left, front, right, and back of the subject, and there is also a six sided mode that adds top and bottom images for even more detail. The README also explains depth scaling, which controls how thick and rounded the generated voxels look, including a manual mode for fine tuning the top, middle, and bottom sections separately. The application is built with Wails, a framework for building desktop apps using Go on the backend and a web based frontend. Building it from source requires Go version 1.21 or newer and Node.js with npm, plus some system libraries on Linux. Ready made downloads are also available from the project's releases page for people who do not want to build it themselves. The author lists a couple of planned improvements, including separating the texture file output and adding a basic 3D editor directly inside the app.
