[App Introduction] Developed using Apple’s cutting-edge ARKit and RealityKit technologies, this app is specifically engineered for devices equipped with LiDAR (Light Detection and Ranging) sensors. Whether you are focused on interior design, object archiving, or simply exploring the 3D world around you, this is the ultimate power tool in your pocket. [Core Features] Professional LiDAR 3D Scanning Real-time Modeling: Utilize ray-casting algorithms to generate environmental meshes in real-time as you move. Intelligent Optimization: Features "Realistic Texturing" and "Glass-Hole Patching" algorithms to ensure your models are as lifelike as possible. Adjustable Parameters: Customize texture precision to find the perfect balance between device performance and visual quality. Multi-format Export: Once scanning is complete, export your work as .obj files for seamless integration with PC software or other 3D editing suites. [Privacy First Commitment] 100% Local: All scanning data and model files are stored exclusively on your device. The "Three Noes" Policy: No ads, no third-party tracking, and no server uploads. Your data belongs to you alone. [Supported Devices] For the full experience, we recommend using an iPhone 12 Pro (or later Pro models) or a LiDAR-equipped iPad Pro.
