Visualize large objects in augmented reality, at real scale
To show a large object (sofa, hot tub, vehicle, machine) in augmented reality at real scale, you need a 3D model with exact dimensions, in meters, and a file light enough for a smartphone. Visuality places it on the floor at 1:1 scale on iPhone (AR Quick Look) and Android (Scene Viewer or WebXR), and can stop customers from resizing it.
No commitment, no credit card required.
The problem: how do you show what doesn't fit in a suitcase?
Industrial machines, agricultural equipment, large-scale furniture, vehicles, metal structures, boilers, solar panels... Many industries sell products whose size makes physical demonstration complex and costly.
The challenges are numerous: transporting a 500 kg product for a client meeting is unthinkable. Renting a trade show space large enough to display a 3-meter machine costs a fortune. And even in a showroom, space is limited — you can only display a handful of products out of dozens or hundreds in your catalog.
The result: your customers must buy from a catalog, a blueprint, or photos. They can't picture the product in their space, assess its actual dimensions, or verify that it fits. This lack of visualization lengthens sales cycles and breeds distrust.
The solution: full-scale augmented reality
Augmented reality solves this problem in a spectacular way. With just a smartphone, your customer can project your product in 3D, at its actual size, directly into their environment. A tractor in a hangar. A machine tool in a workshop. A sofa in a living room. A solar panel on a roof.
The customer can walk around the virtual product, zoom into details, and check proportions against existing elements. They see exactly what the product will look like once installed, without physically moving anything.
How does 1:1 scale work on iPhone and Android?
It all starts with the file. The glTF specification, the format behind GLB files, requires all distances to be expressed in meters. A sofa modeled at 2.40 m long therefore measures 2.40 m once placed in the customer's room. Augmented reality viewers read this size as is: Google states it plainly for Scene Viewer ("1 unit = 1 meter").
- On iPhone and iPad: augmented reality opens in AR Quick Look, built into iOS. Visuality automatically generates the required USDZ file from your GLB, baking in the size set on the object. The customer places the object on a detected surface, then moves or rotates it with their fingers.
- On Android: augmented reality runs through Scene Viewer, Google's tool, or through WebXR in Chrome depending on the device. The model is placed on the floor, or on a wall if you have turned on wall placement.
- Lock resizing: by default, customers can enlarge or shrink the object with two fingers. Tick "Prevent the user from resizing the object": Visuality then passes this instruction to both AR Quick Look and Scene Viewer, and the object stays at 1:1 scale.
- Fix a scale error: if the model was exported in the wrong unit (centimeters or millimeters instead of meters), it appears far too big. The "Object size in percentage" setting allows an adjustment, but the most reliable fix is to correct the export at the source.
The corresponding settings are explained in the documentation: managing the size of a 3D object and floor or wall placement. For definitions, see the glossary entry 1:1 scale.
What file size and how many polygons for a large object?
A large object doesn't need a large file. Its size in meters has no effect on file weight: a warehouse and a ring can have the same number of polygons. What slows a smartphone down is overly detailed geometry and oversized textures. Here are the guidelines published by Apple and Google:
| Criterion | Apple (AR Quick Look) | Google (Scene Viewer) |
|---|---|---|
| Geometry | About 100,000 polygons | Up to 100,000 triangles, ideally 30,000 to 50,000 |
| Textures | One set of 2048 × 2048 pixel textures | 2048 × 2048 pixels maximum |
| File size | No published threshold; the memory needed to display the model matters more | Under 10 MB recommended; above 15 MB, the validator reports an error |
| Scale | Real size, moved and scaled with gestures | 1 unit = 1 meter |
On the Visuality side, very heavy models (especially AI-generated ones) are automatically simplified to about 200,000 triangles when the iPhone USDZ file is created, and their textures are capped at 2048 pixels. It is still better to start from an already optimized model:
- Remove what can't be seen: the inside of a machine, hidden screws or the underside of a vehicle add weight to the file without giving customers anything.
- Replace detail with texture: a grille, a logo or a groove can be painted into the texture (with a normal map) instead of being modeled.
- One object per model: for a range of sizes (3-seat and 5-seat hot tubs), publish one object per size rather than a single model to be resized.
- Test on an entry-level phone: that is the device that exposes overly heavy models, not your team's latest smartphone.
Examples of large products in augmented reality
- Industrial machines and equipment: Present your machines at full scale at your client's site or at a trade show. They can verify that the machine fits in their workshop, that maintenance access is clear, and that connections are compatible. No more transporting a multi-ton machine for a demonstration.
- Furniture and interior design: Sofas, wardrobes, fitted kitchens, walk-in closets — the customer places the furniture in AR within the relevant room and checks dimensions, colors, and style. Returns due to sizing issues drop dramatically.
- Vehicles and machinery: Cars, utility vehicles, construction equipment, agricultural tractors — AR lets you visualize the vehicle in the customer's yard, garage, or job site. Especially useful for build-to-order models not available at the dealership.
- Structures and buildings: Garden sheds, pergolas, conservatories, modular homes, converted containers — the customer visualizes the structure in their garden or on their land before ordering. A decisive selling point for purchases worth several thousand euros.
- Energy equipment: Solar panels, heat pumps, EV charging stations — the customer sees how it looks on their roof or in their garage, making it easier to greenlight the project.
Tips by category of large object
| Category | Placement | What the customer checks | Tip |
|---|---|---|---|
| Furniture (sofas, wardrobes, walk-in closets) | Floor | Footprint, clearance, ceiling height | Lock resizing for a check at 1:1 scale. |
| Kitchens and fitted interiors | Floor | Layout, circulation, door opening | Publish modules (island, tall unit, run of units) and gather them in an object group. |
| Hot tubs, saunas, outdoor furniture | Floor | Footprint on the patio, access, room to step back | Test outdoors in daylight: floor detection is more reliable there. |
| Vehicles and machinery | Floor | Fit in the garage or yard, maneuvering | Heavily simplify the interior and underbody, which can't be seen in augmented reality. |
| Industrial machines | Floor | Floor footprint, maintenance access, connections | Prepare the offline Android app for workshops with no network. |
| Sheds, pergolas, structures | Floor | Position in the garden, height | Allow space: the customer will need to step back several meters to see everything. |
| Screens, signs, wall panels | Wall | Width, mounting height | Turn on the "The object is placed on a wall" option in the object settings. |
What are the limits with very large objects?
- Field of view: at 1:1 scale, a truck or a pergola is bigger than the phone screen. The customer has to step back, which requires space around them.
- Floor detection: the smartphone needs to recognize a surface. A plain, shiny or poorly lit floor makes detection harder; a textured floor and good light make it easier.
- An object bigger than the room: a six-meter machine won't fit in an office. For a meeting-room presentation, leave resizing enabled so the customer can shrink the model onto the table; for on-site validation, lock it at 1:1 scale.
Advantages for businesses
- Massive reduction in logistics costs: No more hauling heavy, bulky products for demonstrations. A single smartphone is all you need to showcase your entire catalog in 3D at full scale.
- Unlimited catalog at every meeting: A sales representative can present dozens of different products with no shipping constraints. The entire catalog is accessible via augmented reality, whether at a client meeting or a trade show.
- Shorter sales cycle: Customers who see the product in their real environment make faster decisions. They can trust the dimensions, appearance, and compatibility with their space.
- Competitive differentiation: Offering augmented reality to your customers positions you as an innovative player. In industries where competitors still show photos in PDFs, AR visualization creates a wow effect that leaves a lasting impression.
How do you set up your large objects on Visuality?
Visuality natively handles objects of all sizes, from jewelry to buildings. Here are the key points for getting the best results with large products:
- Match real-world dimensions: When creating your 3D model, make sure the model's dimensions exactly match the actual product dimensions. Visuality displays the product at 1:1 scale in augmented reality.
- Adjust the placement: Visuality offers floor placement (machines, furniture, vehicles) or wall placement (shelves, panels, screens). Choose the mode that best suits your product.
- Lock the size: the "Prevent the user from resizing the object" option ensures customers always see the product at its true dimensions.
- Use object groups: For a multi-product catalog, create an object group that lets the customer browse different product references from a single viewing interface.
- Prepare for offline use: For demonstrations in factories or on job sites without WiFi, use the Visuality Android app, which works without an internet connection.
