## TO-DOs

- Create a calibration page to allow users to calibrate the position and orientation of their camera, and to configure their chroma key (green screen).

- Allow the Mixed Reality Capture session to be initialized with a JSON file with a saved calibration.

## How to test the example

Alternatively, you can instantiate the calibration with a JSON provided by the user:

```javascript

// ...

const json = `
{
"schemaVersion": 1,
"camera": {
"width": 1280,
"height": 720,
"fov": 38,
"position": [0, 1.5, 0],
"orientation": [0, 0, 0, 1]
},
"chromaKey": {
"color": [0, 1, 0],
"similarity": 0.25,
"smoothness": 0
},
"delay": 4
}
`;

const calibrationData = JSON.parse( json );

const calibration = MRC.Calibration.fromData( calibrationData );

// ...

mixedRealityCapture = new MRC.MixedRealityCapture( calibration );

// ...
