VoxelDraft

Create and export voxel art

VoxelDraft helps users create and refine 3D voxel models through short temporary model references, inspect their geometry, explore them in an interactive 3D preview inside your AI, export OBJ/MTL or compact JSON files, and optionally save or reopen private projects in their VoxelDraft account.

Instructions: Free voxel modeling tools backed by VoxelDraft. Use VoxelDraft's compact instruction stream instead of emitting one JSON object per voxel. Coordinates are integers 0..63. Colors are either #RRGGBB or a zero-based palette index. Commands: ["box",x1,y1,z1,x2,y2,z2,color,hollow?] ["ellipsoid",cx,cy,cz,rx,ry,rz,color,hollow?] ["cylinder","x"|"y"|"z",x,y,z,radius,height,color,hollow?] ["line",x1,y1,z1,x2,y2,z2,color] ["roof","x"|"z",x1,y1,z1,x2,y2,z2,color] (gable roof, axis is ridge direction) ["runs","x"|"y"|"z",color,[[x,y,z,length],...]] (preferred exact/freeform representation) ["points",color,[[x,y,z],...]] (sparse details only) ["erase",x1,y1,z1,x2,y2,z2] ["recolor",fromColor,toColor] ["copy",x1,y1,z1,x2,y2,z2,dx,dy,dz] ["repeat",x1,y1,z1,x2,y2,z2,dx,dy,dz,count] ["mirror","x"|"y"|"z",plane,x1,y1,z1,x2,y2,z2] (plane is a grid boundary 0..64) Prefer box/roof/ellipsoid/cylinder for bulk geometry, runs for irregular silhouettes, repeat/mirror for repeated or symmetric parts, and points only for small details. This usually uses far fewer model tokens than raw voxel JSON. Use the returned modelRef for edit/inspect/render/export/save calls; do not reconstruct the underlying model handle. Anonymous and Free users can create, edit, inspect, export, and receive interactive render URLs without an account. ChatGPT can render results in an interactive Three.js widget. Cached server-rendered PNG images require a linked VoxelDraft Plus account and are subject to image credits and rate limits. Private cloud save/load/list tools use OAuth when requested.
