GPU volume engine

Build detailed voxel models and render final shots.

VoxiGen is a browser voxel editor built for serious scale: 1024³ canvases, responsive raycast previews, path-traced beauty shots, physical materials, CT volume import, and pipeline-ready export.

Everything you need

One editor for scale, AI generation, rendering, materials, data, and export.

Build at billion-voxel scale, generate assets with AI, tune materials, inspect volumetric data, render final shots, and export to the tools already in your pipeline.

Massive scale

1024³ editing unlocks billion-voxel work.

A 1024 by 1024 by 1024 canvas is more than one billion addressable voxels. VoxiGen keeps that scale interactive in a browser, making complex models and large volumes practical without a desktop install.

Build beyond small voxel props into city-scale scenes, dense structures, and high-detail scans.
Streaming keeps inactive regions out of the hot path so the editor can stay responsive.
Every canvas reaches 1024³ — the full engine cap, free plan included.

AI Generations & Agent Builder

Generate images, 3D models, and voxel-ready assets in one tray, or build live with Agent Builder.

AI Generations creates reference images and 3D models you can import or download. Agent Builder is a separate panel for describing a structure and watching editable voxels build live on the canvas.

Choose voxel, detailed voxel, realistic, stylized, or custom style presets before generation.
Tune guidance, seed, and polycount; save or open bundles; import or drag images and 3D into the editor.
Agent Builder: describe a structure and watch it build live on the canvas with editable voxels.

Live final rendering

Raycast and path tracing while you edit.

Use fast raycast mode for clean live lighting, then switch to path tracing for beauty shots. The important part: the render is still the editor view, so you can adjust voxels, materials, sun, threshold, and clips while seeing the final look.

Save screenshots and render stills directly from the viewport.
Raycast view gives a sharp real-time final-look preview for everyday work.
Path tracing converges for higher-quality shots when you want polished output.

Physical materials

Materials, sun, and density are first-class controls.

Palette slots are full material slots, not just colors. Pick from matte, plastic, metal, chrome, glow, glass, frosted, cloud, and tissue presets, then tune roughness, metalness, emission, IOR, and density against a physical sun.

Use roughness, metalness, and emission channels for real surface response.
Glass, cloud, and tissue modes add transmission, volume density, and subsurface-style rendering.
Sun azimuth, elevation, exposure, fog, ground, and environment controls shape the scene lighting.

Scientific volume import

Open NRRD data and dissect it live.

Import NRRD scientific volumes such as CT scans, convert tissue bands into editable layers, and inspect the data with threshold, density, slice preview, smooth interpolation, and cross-section controls.

Open raw or gzip .nrrd files directly in the browser.
Separate tissue bands into layers so scan data becomes editable voxel structure.
Move density and surface thresholds in real time to reveal skin, tissue, bone, or internal detail.

Pipeline export

Export to the tools already in your workflow.

Keep VoxiGen compatible with the rest of your pipeline. Save native VXB, move voxel work through VOX, or export mesh formats for Blender, Maya, game engines, printing, and web delivery.

VXB preserves VoxiGen scenes, with optional password protection.
VOX keeps compatibility with common voxel editors.
glTF, GLB, OBJ, and STL cover web, Blender, Maya, game engines, and 3D printing workflows.

One voxel engine

Create assets and visualize volume data in the same browser.

VoxiGen uses the same GPU volume core for voxel art, AI asset generation, CT/NRRD inspection, final rendering, and export. Start with a model or a scan; the workflow stays in one editor.

Create workflow

Build, generate, render, and ship voxel assets.

Use AI generation, brushes, layers, symmetry, materials, and live final rendering on canvases up to 1024³, then export into the tools already in your pipeline.
