HI3D v3.0 Master API by HI3D
HI3D v3.0 Master is the highest-fidelity tier: 2048³ geometry with a 5M-face budget, for hero assets and 3D printing where the mesh is the deliverable rather than a preview. Generation is deliberately slow — plan for tens of minutes, not seconds.
HI3D v3.0 Master is developed by a third-party provider. Atlas Cloud (operated by Atlas Cloud AI LLC) provides access to it and does not own it. All trademarks belong to their respective owners.
HI3D v3.0 Master
HI3D v3.0 Master is the top of the HI3D line: 2048³ Ultra3D geometry with a 5M-face budget, for assets where the mesh itself is the deliverable. It is deliberately slow — reach for it once a lower tier has already shown you the framing is right. Generation is asynchronous; results are re-hosted on AtlasCloud storage.
Why Choose This?
- 5M-face budget — detail that survives close inspection and physical printing.
- 2048³ Ultra3D geometry — the most faithful reconstruction HI3D offers.
- Up to four views — worth using here more than anywhere else, since a re-run is the slowest of the four tiers.
- PBR out of the box — base colour plus metallic, roughness and normal maps unless you turn them off.
- Six export formats — GLB, OBJ, STL, FBX, USDZ and 3MF from the same request.
Parameters
| Parameter | Required | Description |
|---|---|---|
model | Yes | hi3d/v3.0-master/image-to-3d |
image | Yes | Source image: public URL or base64 data URI. png/jpg/jpeg/webp, up to 20 MB. |
reference_images | No | Up to three more views of the same object, for four in total. |
multi_images_bit | No | Which view slots the images fill, as four 0/1 characters (front, back, left, right). Defaults to the leading slots. |
should_texture | No | Generate textures as well as geometry. Default: true |
enable_pbr | No | Also produce metallic / roughness / normal maps. Default: true. Requires should_texture. |
shading | No | De-lighting strength, 0.0–1.0. Default: 0.5. Requires should_texture. |
rmbg | No | Remove the input image's background before reconstruction. Default: true |
target_polycount | No | Face count, 100000–5000000. Omit to let HI3D pick; recommended here: 5,000,000. |
output_format | No | glb (default), obj, stl, fbx, usdz, 3mf. |
Resolution is fixed at 2048³ Master for this model and is not a request parameter — each HI3D tier is its own model. To change resolution, call a different model.
How to Use
curl -X POST "https://api.atlascloud.ai/api/v1/model/generateImage" \ -H "Authorization: Bearer $AIP_API_KEY" \ -H "Content-Type: application/json" \ --data-raw '{ "model": "hi3d/v3.0-master/image-to-3d", "image": "https://static.atlascloud.ai/media/images/sneaker.png", "should_texture": true, "enable_pbr": true, "output_format": "glb" }'
Multi-view, four photographs of the same object:
curl -X POST "https://api.atlascloud.ai/api/v1/model/generateImage" \ -H "Authorization: Bearer $AIP_API_KEY" \ -H "Content-Type: application/json" \ --data-raw '{ "model": "hi3d/v3.0-master/image-to-3d", "image": "https://static.atlascloud.ai/media/images/sneaker_front.png", "reference_images": [ "https://static.atlascloud.ai/media/images/sneaker_back.png", "https://static.atlascloud.ai/media/images/sneaker_left.png", "https://static.atlascloud.ai/media/images/sneaker_right.png" ] }'
Generation is asynchronous — poll /api/v1/model/prediction/{request_id} until status is completed, then read the model URL from outputs. files gives the same URLs with their format and MIME type, and thumbnail is a rendered preview. Expect tens of minutes — up to roughly 80 minutes has been observed.
Best Use Cases
- Hero assets for film and games — the one model that gets a close-up.
- High-detail 3D printing — where a smoothed-over feature is a visible defect in the print.
- Digital preservation — artefacts and products captured once, at the best available fidelity.
- Reference meshes — a ground-truth model that the lower tiers are then judged against.
Pro Tips
- One object, centred, evenly lit, plain background. Clutter and hard shadows are reconstructed as geometry.
- A three-quarter view reconstructs better than a dead-on front or a steep top-down shot.
- Shooting the back and sides and passing them as
reference_imagesis the single biggest quality lever — bigger than moving up a tier. - Leave
rmbgon unless your image is already cut out against transparency. - Raise
shadingwhen the source photo has strong directional light you do not want baked into the texture; lower it when the lighting is already flat. should_texture: falsereturns the bare mesh sooner — use it when you are going to texture the model yourself.
Notes
- Accepted input formats are png, jpg, jpeg and webp, up to 20 MB each.
reference_imagesmust be views of the same object. Different objects produce a fused, unusable mesh.multi_images_bitmust contain exactly as many 1s as there are images in total (imageplusreference_images); a mismatch is rejected before the request reaches HI3D.enable_pbrandshadingonly apply whenshould_textureis on; they are dropped otherwise.- HI3D's own result links expire one hour after generation. The URLs returned here are AtlasCloud-hosted and stay reachable.
