What Sproxel is

Sproxel is a free, open-source tool for making and editing voxel-based 3D models, treating voxel work as a 3D extension of pixel art. It can generate sprites for custom displays or game engines and supports texture painting and scene editing. Version 0.4 added image import from BMP, GIF, JPEG, PNG and TIFF into a voxel grid, along with OBJ export as quads or triangles without internal polygons. Editing tools added in version 0.5 include grid resizing, draggable tools with previews, voxel outlines, camera snapping and a two-click Line tool. Version 0.6 added projects that hold multiple sprites, a Python plug-in system, Paint3D (.3MP) import and export, slicing, and indexed-color grids with a 256-color palette. The maker describes the project as hosted on Google Code and developed on Windows and Linux using the QT windowing framework. It is listed for Windows, macOS and Linux. The download is described as a package that can be copied into a directory and run directly; it does not include a help file, and users are directed to a manual.
