voxel-icon generation process animation
The project-level generation-process animation — prompt to calibrated macro-voxel still.

The project

voxel-icon is the project behind a consistent family of low-density isometric voxel icons. It bundles the reusable skill, the catalogs and prompts that produce the library, approved native and directed outputs, articulated loop batches, and a procedural Three.js prototype.

02Still icons generation

One isolated subject built from a few large blocks — fixed orthographic three-quarter camera, polished face-lit acrylic, suspended with barely any shadow.

OutputSquare RGB PNG, one subject per image
CameraFixed orthographic three-quarter view
BackgroundExact #F4F4F4, every time
03Color palette modes

Every subject keeps its own colors by default; two directed modes recolor the approved geometry without touching its shape.

nativeDefault — the object's own component colors
directedOne of 40 bundled Oreo-derived presets
aggressivePreset colors across distinct real layers
04Motion loops + post-processing

Motion is opt-in: a four-frame rest → forward → rest → back loop with fixed connections and real 3D pose changes, assembled by deterministic scripts.

Frames4 complete generated keyframes
AssemblyVerified GIF + WebP — no masks, no inpainting
CleanupDeterministic background normalize to #F4F4F4
05Self-contained calibration + references

Closed-loop at runtime: the calibration images are internally generated and the complete palette registry ships inside the skill.

Calibration2 internally generated reference images
References5 documents — style, palettes, 40-preset registry, loop contract
Scripts2 post-processing scripts, Pillow + NumPy
