Sproxel
What it is
Sproxel is a free, open-source 3D interface for creating and editing voxel models, treating cube-based forms as an extension of 2D pixel art. It can generate sprites for custom displays and game engines, and includes texture painting and scene editing. Version 0.4 imports BMP, GIF, JPEG, PNG, and TIFF images into voxel grids, then exports OBJ meshes as quads or triangles with an airtight surface and no internal polygons. Version 0.5 added grid resizing, draggable tools with previews, voxel outlines, camera snapping, and a two-click Line tool. Version 0.6 introduced projects containing multiple sprites, a Python plug-in system, Paint3D (.3MP) import and export, slicing, and indexed-color grids with 256 palette colors. Sproxel is listed for Windows, macOS, and Linux. Its download is a copyable package that runs without installation, while help is provided through a manual rather than an included help file.
For and against
For
- Free and open source
- Imports five common image formats
- Exports OBJ meshes as quads or triangles
- Python plug-in system
- Runs without an installation process
Against
- Package does not include a help file
- Version 0.6 download was win32 only
- Development described on Windows and Linux
The verdict
Sproxel combines voxel editing, image import, OBJ export, and sprite creation in an open-source package. Its copy-and-run distribution is convenient, but users must consult the manual for help.
Who it suits
Sproxel suits people making voxel models, sprites, or game-engine assets. It is also relevant to users who want an open-source tool on Windows, macOS, or Linux.
