Dot3D vs Polyga FlexScan3D

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.

Polyga FlexScan3D is free legacy software for controlling 3D scanners, capturing scans, and processing them into digital 3D models. It can operate multiple scanners, change scanner settings, and recalibrate systems; Polyga states that acquisition takes approximately one second per scan. The built-in mesh editor supports processing, aligning, merging, cleaning, and filling holes. Standard edition tools measure and analyze deviation by comparing two meshes with a color map. Exports include PLY, OBJ, STL, ASC, and FBX. A C++/C# API library and scripting functions expose scanner controls and data processing. Compatibility includes Polyga scanners, most Basler and FLIR monochrome global-shutter cameras, and standard DLP projectors through HDMI. An automatic rotary table supports 360-degree scanning, and color capture works with color machine-vision cameras. The listed minimum operating system is 64-bit Windows 10. Polyga provides a manual but no one-on-one support for custom DIY scanner builds.
