# General Features
Snapdragon Spaces offers a variety of features to help developers create XR experiences. Here is a brief list giving an overview which features are packed into the SDKs for you to create XR experiences.
# Positional Tracking
Positional Tracking precisely maps the environment and estimates the location, position, and orientation of the XR device in six degrees of freedom within 3D space. This enables a developer to understand and track the end-user’s position relative to the world. XR content will render in the scene properly relative to the end user’s location, head position, and orientation.
# Local Spatial Anchors
Local anchors enable XR content to be placed in spatial space at a given location, position, and orientation on the map generated through Positional Tracking and persist them locally over the session.
Please refer to the sample documentation on how to use local anchors:
To save and load anchors during runtime, please refer to specific chapters of the sample documentation:
# Hit Testing
Hit testing can be used to retrieve a physical point in the real world by sending a ray into the world and checking for any hit results.
Please refer to the sample documentation on how to do hit testing:
# Camera Frame Access
The Camera Frame Access feature gives the possibility to query the RGB camera of the XR device. The retrieved data can be used for a variety of purposes like creating remoting solutions or feeding the data into a third party perception library.
