HuanYu · Image-to-3D API

Integrate the capability

An image.
A starting point.

Bring a visual idea into 3D work.

Condition on an image. Build a spatial representation. Bring geometry and materials into design software. HuanYu connects the journey from visual concept to 3D asset through an API.

Delivered through an API

After generation,
design continues.

A concept should lead to more than a presentation. Image-to-3D gives designers a spatial starting point to inspect, modify and organise. Its value is the connection between design stages, not simply another file.

How generation works

Space is more than a picture.
It has to be constructed.

Image conditions, spatial priors and geometric constraints work together: starting from visible surfaces, towards an object that can be viewed from different angles and prepared for editing.

01

Turn the image into spatial conditions.

Silhouette and view conditions

Subject separation and image normalisation define the object. Silhouette, local boundaries, perspective and material cues constrain spatial inference; generative priors supply candidate explanations for the back and occluded regions.

Unseen structure is inferred. Additional views can provide constraints; a complete-looking render is not evidence of the hidden geometry.

02

Make different views describe one object.

A coherent spatial representation

Cross-view consistency is central to image-to-3D. A form that works from the front should preserve its proportions, part relationships and surface continuity from the side. Multi-view conditions help organise a coherent representation instead of a collection of unrelated pictures.

Appearance consistency is considered alongside silhouette, depth and surface-normal relationships.

03

Move from renderable to editable.

Geometry and material assets

Gaussians represent appearance; editing tools need explicit surfaces. Surface constraints and geometry extraction produce a mesh, followed by work on disconnected fragments, normals, topology and polygon budgets. Texture baking and UV organisation connect appearance to conventional material workflows.

Surface extraction, retopology and material preparation are separate steps, not a format conversion.

Single-image generation relies on image priors. Classical 3D Gaussian Splatting reconstructs a radiance field from multiple observed views. They address different problems; Gaussian representations provide a spatial basis for generation and rendering.

Gaussian splatting

Represent appearance
in three dimensions.

Each Gaussian has a position, scale, orientation and appearance. Projected primitives contribute pixels through visibility-aware alpha compositing. Differentiable rendering lets image-space errors inform the spatial representation.

Anisotropic Gaussian → image-plane projection
μPosition
The centre of a primitive in 3D space.
ΣScale and orientation
Covariance defines the ellipsoid’s shape and orientation.
αOpacity
Controls its contribution to compositing.
cAppearance
Represents colour and view-dependent appearance.

A renderable representation is not an editable surface.Gaussians and meshes serve different roles in appearance and geometric editing. Shape, topology and materials still need independent checks during conversion.

Structure for industrial design

Make the change
at the level of a part.

A structured object makes editing addressable.

Our industrial-design research explores part-level generation. Semantics, geometric boundaries and part relationships help organise housings, functional elements and supports into addressable objects, giving local shape changes, material substitutions and design reviews a defined scope.

3D design and content editing

Meshes, materials, hierarchy and transforms provide a starting point for editing, review and scene composition in 3D software.

Downstream engineering

Parametric solids, precise surfaces, dimensional tolerances and assembly constraints must be established and validated in CAD and engineering workflows. Part separation is not engineering-solid generation.

Quality is defined
by the work that follows.

An asset for form exploration, visualisation or further modelling has different acceptance criteria. Translate its intended use into checks across appearance, geometry, materials and scene organisation.

01

Appearance and views

Silhouette drift / part proportions / cross-view consistency

The shape should remain coherent across viewpoints.
02

Geometry and topology

Normals / non-manifold edges / floating fragments / face count

Check the mesh for its next use, beyond the rendered image.
03

Materials and textures

UV overlap / seams / texture dependencies / colour space

Carry the appearance into the destination tool.
04

Asset and scene

Axes / unit conventions / naming / hierarchy / version

Make each delivered object identifiable, traceable and editable.

Without a real-world scale reference, model dimensions depend on an agreed convention. Manufacturing accuracy and feasibility require engineering validation.

From a visual direction
to work on the model.

A transition in an automotive design workflow: choose a concept direction, then inspect its shape and proportions in 3D software. The image establishes intent; the model carries the next stage of work.

API integration

Your software.
A new spatial capability.

Keep your projects, accounts and design workflow. Integrate image-to-3D as an asynchronous capability: submit a task, follow its stages, receive assets and return them to the original environment.

One task. A complete handoff.

A task identifier connects inputs, stages, failure reasons and artifact versions. Execution completion and quality outcomes remain separate.

Asynchronous, traceable execution

Separate submission from result retrieval. Agree on polling or callbacks, timeout handling and duplicate-request policies so a long generation process does not depend on one page request.

Integrate around an artifact contract

Specify model formats, texture references, coordinate systems, units and versions, then validate import in the target software. Available formats, stages and error fields follow the actual service agreement and integration documentation.
