img2threejs: Convert Images into Editable Three.js Models

Introduction

img2threejs is an image-to-Three.js converter that turns reference images into editable procedural 3D models.

Upload a clear image of an object, preview the generated model in your browser, and export readable Three.js TypeScript code and a structured JSON specification.

Unlike many image-to-3D tools that return a single opaque mesh, img2threejs creates named components, materials, geometry, and transforms. This makes the result easier to inspect, modify, animate, and integrate into a web application.

img2threejs is designed for developers, designers, indie makers, and product teams that need a fast starting point for browser-based 3D.

What Can You Use It For?

Interactive Product Previews

Convert a product photo into an initial interactive 3D model for e-commerce pages, product explainers, landing pages, and configurators.

Because the output contains named parts, developers can change materials, highlight features, rotate components, or connect individual parts to clicks and application state.

Game Prop Prototypes

Create a structured draft of a tool, appliance, weapon, furniture item, or mechanical object before investing in final 3D modeling, texturing, collision geometry, and animation.

Three.js Creative Coding

Use the generated TypeScript as a foundation for WebGL experiments, educational projects, technical demonstrations, interactive storytelling, and browser-based visualization.

The dimensions, materials, colors, components, lighting, and animation can all be modified with a normal Three.js and Git workflow.

Technical and Educational Models

Named components make it easier to explain how an object is assembled, highlight individual parts, and build interactive technical diagrams or educational experiences.

How Does It Work?

1. Upload a Reference Image

Upload a PNG or JPG containing one complete, clearly visible object.

For better results, use an image with:

A simple background

Clear edges and silhouette

Stable lighting

Limited obstruction

Enough resolution to show important details

Product photos and isolated hard-surface objects usually work better than people, animals, hair, fabric, glass, smoke, or crowded scenes.

Agent mode supports up to three reference images. Extra angles can help clarify hidden connections, controls, attachments, and smaller details.

2. Analyze the Object

img2threejs examines the object’s silhouette, components, proportions, orientation, materials, repeated elements, and recognizable details.

Visible parts can be reconstructed with greater confidence. Surfaces or connections that are not shown in the images must be approximated.

3. Build the Three.js Model

The visible structure is converted into a validated procedural specification containing named parts, geometry, materials, dimensions, positions, rotations, and component relationships.

A deterministic builder then assembles the specification into a structured Three.js scene.

4. Preview and Export

The result appears in an interactive browser preview. You can orbit around the model, zoom in, inspect its structure, and compare it with the reference image.

You can then export:

Editable Three.js TypeScript

A structured JSON model specification

The TypeScript factory returns a reusable THREE.Group, allowing you to adjust dimensions, replace geometry, modify materials, attach events, or add animation.

img2threejs currently focuses on editable code rather than GLB, OBJ, FBX, or STL export.

Quick Mode and Agent Mode

Quick Mode

Quick mode is designed for fast experimentation and simple procedural drafts.

It is useful for testing reference images, exploring ideas, previewing results, and downloading editable Three.js code.

Quick mode includes three free generations per day. After the daily free allowance, each Quick generation costs 1 credit.

Agent Mode

Agent mode is intended for more detailed or complex objects.

It uses a longer cloud workflow involving reference analysis, procedural construction, rendering, visual review, and refinement. Multiple reference images can be used to reduce uncertainty.

Agent jobs continue running in the cloud even if you close the browser. Sign in again with the same Google account and open Generation history to check the progress or view the result.

Agent mode is not free because it consumes significantly more AI model capacity and cloud computing resources.

Pricing

Agent jobs are priced according to their estimated complexity and usually cost 35–50 credits.

The quote may consider:

Object complexity

Number of visible components

Number of reference images

Repeated details

Material variety

Hidden or ambiguous connections

Expected rendering and review effort

The exact price is shown and locked before generation begins.

If the system produces a saved, viewable result, the quoted credits are consumed even if the model still needs manual refinement. If no viewable result is produced, the reserved credits are returned in full.

Credit Plans

| Plan | Price | Permanent Credits |

|---|---:|---:|

| Starter Monthly | $14.99/month | 300 |

| Starter Yearly | $149/year | 3,600 |

| Pro Monthly | $39.99/month | 800 |

| Pro Yearly | $399/year | 9,600 |

Purchased credits do not expire. The number of Agent generations available depends on the complexity quote for each job.

What Results Should You Expect?

img2threejs creates a real, multi-part Three.js scene, but the result is a procedural approximation—not a photo-grade 3D scan.

A single image cannot reveal exact depth, real-world scale, hidden surfaces, internal structures, or obscured connections. Additional views reduce uncertainty but do not turn the workflow into photogrammetry.

The strongest results usually come from isolated hard-surface objects with clear structure. Organic subjects, hair, fabric, transparent materials, highly reflective surfaces, complex vehicle bodies, and exact human likeness still require specialist 3D tools.

img2threejs is not intended to replace Blender, Maya, or professional 3D artists. It provides a fast, readable, browser-native starting point that developers can continue improving.

Get Started

Upload a clear image of one object.

Use Quick mode for a fast draft.

Add extra views when hidden details matter.

Choose Agent mode for a more detailed reconstruction.

Review the credit quote before confirming.

Preview and export the generated TypeScript and JSON.

Continue editing the model in your own Three.js project.
