Polyga PointKit vs Structure

Polyga PointKit is a toolset for processing, scanning, analyzing, and sharing 3D point-cloud and mesh data. PointKit Scan runs on Windows and prepares scan data by importing, aligning, cleaning, decimating, remeshing, inspecting, and exporting it. Alignment works on two or more selected meshes when their captured areas overlap sufficiently. After alignment, a finalization tool can combine scans into one mesh and apply additional processing. A lasso tool selects and deletes mesh sections. Supported capture sources include desktop and laser scanners, 3D cameras, photogrammetry, LiDAR, and other 3D devices. Exports include PLY, STL, OBJ, PBN, ASC, E57, LAS, and LAZ. PointKit Scan includes controls for connecting scanners and sharing data with PointKit View. The offering also lists a cross-platform web viewer, SDK, API access, mesh reconstruction, point-cloud tools, and real-time capture. PointKit is freemium, with a free plan and trial. Premium costs $99 a month for one active license and includes XTract3D 2 and PointKit.

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.
