Or you register and share the scan in the Polycam community. If you want to share a real 3D view, then the model has to be published on such a platform as Sketchfab, for example. Basically, these are the recorded views of 3D scans. Video making is an easy and straightforward feature and handy for sharing. When scanning, I usually slow down for a little bit in places with thin walls or tricky surfaces so that the software has time to capture properly. Preview mode is the best guidance in the majority of LiDAR 3D apps including Polycam. This is helpful in case you need to retrieve some of the images or retry the photo set on other photogrammetry software. Photo set can be downloaded as a Zip file. It is better to do the upload later via a faster broadband, for example. Uploading may eat up a lot of battery charge. NB! Capture now – process later to save the battery life. This function is recommended for scanning small objects including when they are on the side during the process. After taking a photoset, you will see the Use Object Masking toggle, which is above Upload & Process button. Advanced feature to capture small objects from all angles. I would recommend following the basic photogrammetry rules, like avoiding the shiny objects, restart the capture if an object moved, etc. It is recommended to take 20-250 images before uploading them to the cloud. If you plan to 3D scan for 3D printing, for example, object capturing in Photo mode produces a much better result. However, to view the mesh I needed a separate software as I could not find that option in the app itself. Like with the stone pillar above, there is a slight difference in the object previews, while meshes, in reality, have a big difference. Sometimes it is difficult to see the significant difference between LiDAR and Photo Mode results. Stone Pillar – LiDAR vs Photo Mode – Mesh Difference Also, LiDAR is handy when there is a low-lighting situation or the object has a small number of features, walls for example.
Only if we want to 3D scan large objects (houses, rooms) or the scenery, we would need to take multiple photo sets and stitch the objects together manually, when LiDAR may provide us with a lower quality result, but in a matter of seconds. If to compare the end quality, Photo Mode provides better results, I would say, for everything. As the LiDAR’s result comes very quickly, it is easy to get the feel of where to pay attention when taking the photos in the Photo Mode. The capture in LiDAR plays as a sort of a warm-up. Which Mode to Use: LiDAR or Photo? – Bothįirst of all, if an object or scenery is important for you, I would recommend capturing it using the LiDAR mode to start with. While Android users are waiting for Polycam Android version, they can try a handy Polycam for Web feature. Update: Polycam announced the Android version. We have plans to create an Android version by the end of the year. It could definitely be used with an Android device since the mobile device is just uploading to a computer that does the actual reconstruction. Photo Mode is powered by Apple’s Object Capture. According to Polycam, an Android version of the application with the Photo Mode feature is expected to be released by the end of this year. Photo Mode should be working on all iOS devices.

Polycam is one of the first mobile apps that enabled uploading photo sets to the powerful PC/Server in the cloud. Then processing photo sets in photogrammetry software is usually done on a relatively powerful PC or in the cloud via PC (f/e Autodesk ReCap software). If LiDAR technology on iPhones became a significant time-saver for processing certain scans (sceneries, murals, streets). LiDAR and Photo modes give the ability to capture 3D objects or the scenery using smartphones in two ways.
