Overview
Voxel Builder is a voxel-based 3D modeling application for creating and editing voxel scenes. It includes terrain, cube, sphere and isometric generators, alongside interactive modeling, symmetric drawing and painting, transforms and color groups. Rendering tools include a Three.js sandbox, GPU path tracer, basic PBR rendering and post-process effects. The app can voxelize GLB, OBJ, STL and PLY models, as well as images and Unicode or emoji text. It saves and loads JSON and MagicaVoxel VOX files, and exports GLB, GLTF, OBJ, STL and PLY. Local storage, snapshots, quicksave, undo and redo are available, with snapshot backups shareable in ZIP archives. A Blender importer script is included, and baked GLB meshes can be used with Blender and other 3D software. The project describes the app as portable and usable online or offline, with no ads, trackers or logging; its code is GPL-3.0. Browser use is supported on desktop and mobile, and Electron downloads are listed for Linux x64 and Windows x64.
Who it is for
Voxel Builder suits people making voxel models who want browser or Electron access and support for several model formats. The project recommends a tablet with a pen or a Wacom tablet for the best experience.
What is good
- Includes terrain, cube, sphere and isometric generators.
- Voxelizes models, images and text.
- Exports GLB, GLTF, OBJ, STL and PLY.
- Supports undo, redo and ZIP snapshot backups.
- Usable online or offline.
What to know first
- High voxel volumes can reduce frame rates.
- Browser storage is limited.
- Geometry animations are unsupported for GLB voxelization.
- No animation tools.
Verdict
Voxel Builder brings modeling, rendering and format conversion into one voxel application. Consider its performance and browser storage limits for dense scenes or larger projects.
