How to Turn a Single Photo Into a 3D Model With Hi3D

Ever look at a photo and think: that would make a perfect 3D asset? Hi3D's Image to 3D feature makes that happen. Drop in one image, and the AI reconstructs it into a full 3D model — geometry, texture, and all — ready to spin around in a viewer, download, or drop straight into your pipeline. This tutorial walks you through the entire workflow, from upload to finished model.

1. A Hi3D account
2. A reference photo in JPG, JPEG, PNG, or WebP format, under 20 MB
3. Optional: a second image if you want to compare different styles

There are two ways in. From the homepage, look at the left navigation bar, click General, and you'll land on the Image to 3D tab by default. Alternatively, click Creative Space in the top nav — same destination. You'll see two tabs at the top of the left panel: Image to 3D and Multi-view to 3D. Make sure Image to 3D is selected.

Click inside the dashed upload zone, or just drag and drop your image straight onto it. Accepted formats are JPG, JPEG, PNG, and WebP — file size limit is 20 MB. Not sure what to use? Scroll down past the upload zone and you'll find a row of Example thumbnails. Click any one of them to load it as your input image. The tutorial demonstrates with a richly detailed old treasure chest photo, which is a great choice because it has a lot of surface and structural complexity to test the AI against.

Click the Model Version dropdown. Three options:

1. v2.0 (New): High-fidelity textures, 3D-print ready. This is the one to use for final-quality output.
2. v1.5: Stable geometry, slightly faster. Good if you're on a tight credit budget or just need to rough something out quickly.
3. Note: v2.1 is now available as well, offering further improvements in reconstruction accuracy and texture fidelity. If you see it in the dropdown, go with that.

For anything you plan to use seriously, stick with v2.1.

Open the Resolution dropdown. You'll see four tiers:

1. 512P³ — Ultra-fast, low-cost. Use this for quick previews and tests, not final output.
2. 1024P³ — Balanced, general use, efficient. A solid middle ground.
3. 1536P³ — High precision, complex topology, fine detail. Good for most production work.
4. 1536P³pro — Flagship, commercial-grade, print-ready. The highest quality output available; use this when the result really matters.

Note: v1.5 gives you all four options. v2.0 only offers the top two — 1536P³ and 1536P³pro — since it's built for high-fidelity work. For the tutorial, 1536P³pro with v2.0 is selected.

Under Generate Type, pick one of two modes:

1. Geometry+Texture: Generates the full model in one shot — geometry reconstruction plus color and material textures applied. This is what most people want.
2. Geometry only: Produces a clean white mesh with no texturing. Choose this if you want to inspect the raw geometry first, or if you plan to texture the model yourself in another application.

The tutorial runs through both options. Starting with Geometry-only is a smart move if you're evaluating reconstruction quality before spending credits on texturing.

Once everything is set, hit the green Generate button at the bottom of the panel. The credit cost is shown right on the button before you commit — 60 credits for the Geometry-only pass shown in the tutorial. Sit back while the AI processes. When it's done, your model appears in the 3D viewport.

With Geometry mode, what you get is a white mesh — all the shape, none of the color yet. And the shape is where the real story is. Rotate the model in the viewport (click and drag) to check it from every angle. The treasure chest in the tutorial comes back with nearly 1 million vertices and 2 million faces, capturing the carved decorative border trim, hinges, dome lid curve, and lock plate in crisp detail. The structural reconstruction is genuinely precise — you can compare it side by side against the original photo using the reference image panel that pops up on the right.

Ready to bring the model to life? Click the Texture button in the toolbar at the bottom of the viewport (costs 15 credits). The AI takes the geometry you just generated and wraps it with color and material maps derived from your original image. When it comes back, you're looking at dark walnut-colored wood planks, aged gold metalwork with natural patina, worn rivets, and ornate engraved trim — all with a 4096×4096 UV texture map. One thing worth highlighting: Hi3D intelligently strips out the lighting and shadows baked into the original photo, so the model's surface responds correctly to light sources in your scene — whether that's a game engine's dynamic lighting system or a 3D renderer's area lights — rather than having the original photo's lighting baked permanently into the texture. The result is a clean albedo you can light however you want, without fighting against shadows that were already there before you started.
