Create a new webcam-based source of data with the specified settings.

Arguments

• settings: object, optional. An object with the following keys (all are optional):
  • resolution: Resolution. The desired resolution of the video. The higher the resolution, the longer it takes for the video to be uploaded to the GPU, which impacts performance. The lower the resolution, the less accurate the tracking will be. Suggested values: "md+", "md", "sm+", "sm".

  • constraints: MediaTrackConstraints. Additional video constraints that will be passed to navigator.mediaDevices.getUserMedia().

Returns

A new webcam-based source of data.

Example

const webcam = AR.Source.Camera({
    resolution: 'md+',
    constraints: {
        facingMode: 'environment' // will prefer the rear camera on mobile devices
        //facingMode: 'user' // will prefer the front camera on mobile devices
    }
});

Properties
