Strengths and trade-offs
Polyga FlexScan3D — where it wins
- Covers capture, alignment, merging, cleanup, measurement, and inspection
- Supports point-cloud and mesh workflows with several export formats
- Includes scripting, command-line access, and hardware integrations
Where it doesn't
- Windows 10 64-bit is the supported operating system
- Hardware support centers on Polyga and specified vision components
- Polyga currently classifies the software as legacy
Open3D — where it wins
- Free and open source across Windows, macOS, and Linux
- Python and C++ APIs support programmable scanning workflows
- RGB-D reconstruction, registration, rendering, and GPU acceleration
Where it doesn't
- Requires development work rather than a turnkey scanning workflow
- Camera support centers on Intel RealSense and Azure Kinect
- Broader scanning workflows depend on integrating the available components
