What’s the purpose of an AR SDK?
Simplifies one or more of:• Recognition – What to track• Tracking – Where it is (3D pose)• Content rendering – Your Interesting Stuff

Tracking Types
• GPS + Compass + Gyro + Accelerometer• Marker (Fiduciary, frame, etc)• NFT (2D images)
• Pre-trained• Cloud recognized• User-defined
• 3D (Pre-trained point cloud)• Live 3D (SLAM)• Face, Fingers, Body• Robot

SLAM Differences
Pointcloud vs. metaio SLAM:- Pointcloud creates a ground plane from points- metaio aligns to gravity
