Dot3D vs Polycam

Dot3D is professional 3D capture and scanning software for digitizing complex environments on mobile devices. It supports large indoor and outdoor scene scans, loop closure, appending scenes, and annotations during capture. Scan refinement options include coded targets, survey control coordinates, distance constraints, wall-to-wall measurements, and planarity constraints. Dot3D Edit offers editing and processing without scanning, including cropping, measurement, annotation, and export. Supported platforms are iOS, Android, and Windows. Capture inputs include iPhone Pro and Pro Max models from 12 onward, iPad Pro from 2020 onward, Orbbec Gemini 336L, listed Intel RealSense cameras, DPI-10, and DPI-X. Prime supports Orbbec and RealSense depth cameras on Windows and Android; its real-time RTK/GNSS feature requires iOS. Exports include DP, E57, LAS, LAZ, PTS, PTX, PLY, PTG, RCS, and POD, with RCS and POD limited to Windows. The maker says captured data stays on the local device unless explicitly sent to DotProduct. The seven-day all-access trial reverts to Free mode without automatic charge, but Free mode has no exports. Dot3D is based in Norwood, Massachusetts, USA.

Polycam is AI reality capture software for professionals who document, measure and design. It uses AI-assisted photogrammetry and LiDAR to capture spaces, construction sites, facilities, products and materials in 3D, and it can create shareable 3D object models. Users can generate customizable 2D floor plans; paid plans also list instant 3D and editable 2D floor plans. Drone footage can be processed into expansive 3D models. Polycam is available on Android, iOS and web browsers, though Space Mode scanning is limited to compatible iOS devices. Listed exports include GLTF, OBJ, FBX, DAE, STL, USDZ, point cloud formats and DXF; named workflows include Blender, Unity, SketchUp and Xactimate. Free access has limited space, object and AI captures, with GLTF exports and public link sharing. Basic costs $150 a year, equivalent to $12.50 per month when billed yearly. Seven-day trials are offered with annual Basic and Business plans, but not monthly plans or Enterprise. Business is listed at $400 a year and Enterprise at $1,200 a year.
