Dot3D vs Structure

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.

Structure builds 3D scanning hardware and software for medical, clinical, and industrial applications. Its technology supports orthotic and prosthetic fitting, wound measurement, surgical planning, and patient monitoring. The Structure Sensor 3 attaches to compatible iPads and provides millimeter depth accuracy for body measurements. Developers can use the Structure SDK for raw depth frames, mesh extraction, foot measurement, and offline licensing; the SDK also supports apps in healthcare, industrial inspection, retail fit-tech, and augmented reality. Structure Capture exports STL, OBJ, and PLY CAD files directly from compatible iPhones and iPads, and includes a Scan Quality Indicator. The SDK detects foot landmarks such as metatarsals, heel point, and arch height. Capture works with specified TrueDepth-enabled iPhones and iPads running iOS 16 or iPadOS 16 or later, and Structure Sensor ST01, ST02, and ST03. A seven-day SDK trial costs nothing. Capture costs $19.99 a month or $199 a year; the Structure Sensor 3 costs $995, paid once. Commercial SDK distribution requires a contract and a quote.
