SimLab AR/VR Viewer vs RTAB

SimLab AR/VR Viewer allows you to explore interactive 3D and VR experiences created using SimLab Composer or SimLab VR Studio. These tools prepare 3D models from more than 30 supported file formats and convert them into fully interactive scenes that you can open and view on your Apple device. Important:
3D files (such as FBX, OBJ, or USDZ) must be prepared in SimLab Composer or SimLab VR Studio before viewing. Direct file import into the app is not supported. Features: • View complete VR training and educational simulations.
 • Explore mechanical assemblies and interact with prepared 3D objects.
 • Deliver hands-on demonstrations and immersive learning experiences. 
• Add measurements and notes for review and collaboration.
 • Join multi-user sessions to communicate and work together in real time across supported platforms.
 • Sync wirelessly with SimLab Composer or SimLab VR Studio to transfer and update VR experiences. Ideal For: • Architects and engineers: Review designs and model details in an immersive environment.
 • Educators and trainers: Present interactive lessons and simulations.
 • Designers and product teams: Showcase prototypes and concepts.
 • Collaborative teams: Meet inside shared VR spaces to review work together. To create VR experiences that can be viewed in this app, use SimLab Composer or SimLab VR Studio on desktop.

RTAB-Map (Real-Time Appearance-Based Mapping) is an Open Source LiDAR / RGB-D / Stereo Graph-Based SLAM (Simultaneous Localization and Mapping) approach based on an online incremental appearance-based loop closure detector. The loop closure detector uses a bag-of-words approach to determinate how likely a new image comes from a previous location or a new location. When a loop closure hypothesis is accepted, a new constraint is added to the map's graph, then a graph optimizer minimizes the errors in the map in real-time. An optional memory management approach can be used to limit the number of locations used for loop closure detection and graph optimization, so that real-time constraints on large-scale environnements are always respected. ARKit's visual inertial odometry (VIO) is used as the SLAM front-end for RTAB-Map (the SLAM back-end). * Note that unlike other scanning apps that optimize the map only after mapping, with RTAB-Map you get loop closure detection and map optimization online so you can have a live feedback to know when you have enough constraints in the map for good global optimization before stopping the scan. *** 3D reconstruction available only with LiDAR sensor. Features: * Online 3D scanning/mapping of the environment. * Online loop closure detection and map correction. * Save in DB format (RTAB-Map desktop and rtabmap_ros format). * Export in PLY, LAS or OBJ. * Multi-session mapping (save and continue later). * Use Apriltags to help finding loop closures in textureless environments. * Mixed AR/VR First-Person in visualization mode. * Raw ARKit data recording (up to 60 Hz!), useful to record long sessions without comprising battery life.
