  • create_voxel_model Create an editable VoxelDraft model from compact commands. Returns a short modelRef for later plugin calls and does not save to Cloud Projects. 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 ze
  • edit_voxel_model Edit the temporary model identified by modelRef and return a new modelRef. This does not modify a saved cloud project. 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. C
  • inspect_voxel_model Inspect a temporary VoxelDraft modelRef. Returns voxel count, command count, bounds, and colors.
  • render_voxel_model Preview a VoxelDraft modelRef. ChatGPT can render an interactive Three.js/WebGL widget; everyone also receives an interactive WebGL URL. Signed-in VoxelDraft Plus users may additionally receive a cached PNG when includeImage is true.
  • export_voxel_model Create direct download URLs for OBJ+MTL or compact VoxelDraft JSON from a modelRef.
  • save_voxel_model Save the temporary model identified by modelRef to private VoxelDraft Cloud Projects. Requires project-write OAuth scope. Pass projectId to update an existing owned cloud project.
