What Is Polycam?

Polycam is a mobile 3D scanning application available on both Android and iOS. It lets you capture real world objects, rooms, and even entire buildings as detailed 3D models, floor plans, and point clouds. Architects, designers, contractors, and 3D artists use it to bring physical spaces into their digital workflows.

The core promise is simple: point your camera, move around the subject, and let the app handle the rest. On devices with LiDAR, the process is faster and more accurate for interiors. On standard phones, photogrammetry delivers detailed object scans with impressive visual fidelity.

How Polycam Works: The Capture Process

The app offers three main capture modes, each designed for different subjects and outcomes .

Photogrammetry Mode (All Devices)

This mode works on any smartphone. You take multiple photos of an object from every angle, ensuring 60-80% overlap between each shot . The app analyzes these images, finds common points, and reconstructs a 3D mesh. For complex subjects, you might need anywhere from 20 to over 150 images . Processing happens either on your device or in the cloud, depending on your plan.

LiDAR Scanning (Apple Devices Only)

LiDAR, short for Light Detection and Ranging, sends out pulses of infrared light and measures how long each takes to return . This creates a real time 3D map as you move through a space.

On Pro iPhones (12 and later) and iPads (2020 and later), Polycam uses LiDAR for Space Mode and Floorplan Mode . The app generates a 3D mesh, a virtual walkthrough, and a floor plan from a single scan session . The typical accuracy for interior captures is within half an inch .

360 Capture (Apple Devices)

This mode creates immersive panoramas by rotating your iPhone in a complete circle. The app stitches the images together, and AI fills any gaps in the final image . This works well for virtual tours and sharing spaces without needing precise 3D geometry.

Polycam vs Other 3D Scanning Options

 

Getting Better Results With Polycam

Capture Tips for Better Results

Lighting makes or breaks a Polycam scan. Harsh shadows confuse the photogrammetry algorithm. Flat, even light gives it clean data to work with. Overcast days work better than direct sunlight. Indoors, turn on all available lights and avoid mixing warm and cool color temperatures.

Photo overlap matters more than you might think. Aim for at least 60 to 80 percent overlap between consecutive images. Move around your subject in a circular pattern, keeping your distance consistent. Take photos from multiple height levels too, not just eye level. Low angles and high angles give the software more reference points.

Object positioning affects what you can capture. Place your subject on a non-reflective surface. Avoid glass, polished metal, or anything shiny. These surfaces create reflections that the software interprets as real geometry, leading to distorted results. If you cannot avoid reflective surfaces, dust them with a light coating of temporary spray.

Common mistakes ruin good scans quickly. Moving too fast between photos creates gaps in the data. Not enough photos leaves holes in the mesh. Poor lighting produces noisy point clouds. Holding the phone too close or too far from the subject reduces resolution. Taking photos in a straight line rather than orbiting the subject limits the software’s ability to reconstruct depth.

Choosing the Right Export Format

Mesh formats work best when you need a solid, watertight model. OBJ and FBX are the industry standards for animation, game engines, and 3D printing. STL is the go-to for 3D printing specifically. GLTF is ideal for web-based 3D viewers and AR applications.

Point clouds excel in surveying, BIM workflows, and large-scale spatial documentation. PLY and LAS formats preserve color information and spatial accuracy. DXF integrates with CAD software for architectural and engineering work. XYZ is a simple text-based format useful for custom data processing.

Software compatibility drives your format choice. Blender handles OBJ, FBX, and STL natively. SketchUp works with DAE and SKP. AutoCAD and Revit prefer DXF and DWG. Unreal Engine and Unity use FBX and GLTF. Plan your export format based on where the model needs to go.

File size considerations affect workflow speed and storage. Point clouds take up more space than meshes. High-polygon meshes load slower in editing software. Exporting lower-resolution versions for previews saves time during iteration. Use the Polycam Pro processing options to balance quality against file size for your specific use case.

Free vs Pro: Making the Decision

The free version of Polycam gives you access to basic capture, viewing, and GLTF exports. Public sharing works through the Explore community. Cloud processing limits apply, with a cap on how many captures you can process per month. This is fine for testing the app and learning the workflow.

Pro features unlock what makes Polycam useful in professional settings. All export formats become available. Processing limits increase significantly. Private sharing lets you control who sees your captures. Team collaboration tools appear in the business tier. For architects, designers, and contractors sending deliverables to clients, Pro is the practical starting point.

The free trial period exists through the App Store or Google Play subscription model. New users get a limited number of free captures before the limits apply. This gives you enough room to test the app on real projects and decide whether Pro fits your workflow. Most professionals find the subscription cost acceptable compared to the price of a dedicated 3D scanner or laser measuring tool.

Conclusion

Polycam is a mobile first 3D scanning tool that does one thing well: it captures real world objects and spaces as usable digital assets. Architects use it for floor plans and interior documentation. 3D artists use it for reference models and game assets. Contractors use it for on-site measurement and existing condition reports.

What it does best: turning a smartphone into a practical 3D scanner without requiring expensive hardware or extensive training.
