For those who don't want to log in, here's the snippet of their features from https://creator.magicleap.com/downloads/lumin-sdk/overview

  #### C API

  - Audio: Stereo audio output and voice microphone recording are supported.
  - Camera: Capture still images and videos from the color camera.
  - Dispatch: Allows apps to open URLs using the Magic Leap Browser or other apps.
  - Eye Tracking: Ability to retrieve fixation point position and eye centers. Blinks can also be detected.
  - Graphics: OpenGL ES, Desktop, and Vulkan rendering paths.
  - Hand Gestures & Key Point Tracking: Recognize the user's hand poses (gestures) and track the position of identifiable points on hands such as the tip of the index fingers.
  - Head Tracking: Headpose is tracked in full six degrees of freedom (DOF).
  - Image Tracking: Track the position and orientation of specified image targets in the user’s environment.
  - Input (Control / MLMA Support): Retrieve either 3 DOF (orientation) or full 6 DOF (position and orientation) from the Magic Leap Control. Detect button and touchpad presses and the analog trigger. Trigger values range from 0 to 1. A range of touchpad gestures are also supported, as are haptic vibration and LED ring feedback. This interface works seamlessly with both physical Magic Leap Controls and the Magic Leap Mobile App.
  - Light Tracking: Provides information (luminance, global color temperature) about the ambient light of the user's environment.
  - Media Codec: Low-level, hardware-accelerated media encoding and decoding.
  - Media Player: Simple, straightforward media playback interface.
  - Meshing: Converts the world's depth data into a connected triangle mesh that can be used for occlusion and physics.
  - Music Service: Supports connecting and listening to a streaming music service.
  - Occlusion: An interface for feeding depth data to the Magic Leap platform for hardware occlusion.
  - Planes: Recognize planar surfaces in the user's environment for placing content. This includes semantic tagging for ceilings, floors, and walls.
  - Raycast: Fire a ray and get the point of intersection with the world's depth data.
  - Secure Storage:Save data from your app to the device's encrypted storage.

  #### Magic Leap Remote

  - Supported ML Remote APIs:
      - Head pose
      - Eye tracking
      - Hand Gestures and Keypoint tracking
      - Control Input
      - World Raycast
      - World Meshing
      - World Planes
      - Image Tracking (Simulator only)
      - Graphics API (OpenGL)

  - Properties panel in the GUI lets you manually set the state of API data such as head pose, detected gestures, and so on.
  - Shows the virtual room in a Mini Map as well as an Eye view that depicts your application content composited over the virtual room.
  - Supports gamepad, keyboard, and mouse bindings. Use a gamepad to drive head position, define keys to trigger detected gestures, and more.
  - The bundled virtual room generator app procedurally generates random rooms that you can customize even further to test your game logic in the Simulator.
  - Experimental support for faster graphics rendering in ML Remote can be enabled by setting the environment variable ML_REMOTE_ENABLE_GPU_SHARING = 1. This feature is experimental, because it has not yet gone through rigorous testing and might lead to a crash or visual artifacts under some circumstances.
