An advanced, robust, and usefull for converting 2D pixel art into high-quality 3D voxel models. Designed for and by game developers.
Voxelizer takes your 2D sprites and intelligently extrudes them into 3D voxel models for use directly in your projects.
It goes beyond simple extrusion: Voxelizer incorporates advanced camera controls, robust error handling, and powerful mesh optimization, ensuring your creations look faithful to your designs.
No generative AI. No hallucinations. Only mathematics and advanced algorithms.
- Single-image and multi-view voxel reconstruction
- Front, back, side and top reference views
- Greedy mesh optimization
- Palette editing and material configuration
- Perspective and orthographic previews
- VOX, OBJ/MTL, GLB and FBX export
- Web Worker processing with bounded memory budgets
- Automated regression tests
- Alpha Thresholding: First, the 2D image is converted into a binary mask based on the alpha (transparency) value of each pixel.
- Volume Extrusion: This mask is then extruded along the Z-axis to create the initial, dense cloud of voxels.
- Greedy Meshing: This is the secret sauce. The algorithm sweeps through the voxel cloud and merges adjacent faces into large, optimized polygons, dramatically reducing geometric complexity.
- Camera Projection: The 3D model is rendered to the screen using precise Model-View-Projection matrix transformations. The orthographic projection parameters are mathematically sound, providing a stable, true-to-design, what-you-see-is-what-you-get experience.
- Quality Assured: The entire core logic is backed by a suite of 205 regression tests, ensuring every feature, from camera controls to memory budgeting, is stable and predictable.
Zero setup required. Just clone the repository and open index.html directly in your browser.
This project is developed using Spec-Driven Development (SDD) to ensure that every feature is well-planned, documented, and robustly implemented.
- To run the test suite:
npm test # or with detailed output: npm run test:spec
- To run syntax checks on all scripts:
npm run check
