Add VR or AR support to @angular-three projects

Enter VR

Add webvr to ngt-canvas to enable Web VR support

<ngt-canvas webvr [camera]="{ fov: 55, position: [0, 2, 4]}">

Add vr-controller to add left and/or right controllers into a scene. Index 0 is left controller, Index 1 is right controller.

<vr-controller showcontroller trackedpointer [index]="1"></vr-controller>

Add directives to vr-controller to add behaviors depending on needs

• showcontroller - shows controller
• trackedpointer - shows ray to point at stuff
• teleport - teleport to new location on floor. Requires [floor] and [marker]

<vr-controller teleport showcontroller trackedpointer navhome 
               [marker]="left.instance.value" [floor]="floor.instance.value">
</vr-controller>

All behaviors can be enabled/disabled at runtime on either controller. The allows behaviors to be switched between controllers if needed.

<vr-controller [showcontroller]="enableshow" [trackedpointer]="enabletracking">
</vr-controller>

Enter AR

Add webar to ngt-canvas to enable Web AR support

<ngt-canvas webar [camera]="{ fov: 55, position: [0, 2, 4]}">

Add ar-controller to into the scene to add object interaction. Index 0 is first finger controller, Index 1 is second finger controller.

<ar-controller (tap)="tap($event)" [index]="1"></ar-controller>

tap(event: XRInputSource) {
  event.gamepad // x/y screen coordinates [-1 to 1, -1 to 1]
}

Add ar-gestures into the scene to detect various gesures.

<ar-gestures 
  (press)="press($event)"
  (tap)="tap($event)"
  (swipe)="swipe($event)"
  (pan)="pan($event)"
  (pinch)="pinch($event)"
  (rotate)="rotate($event)">
</ar-gestures>

The following gesture events are available:

The controller position and matrixWorld are included

• press - position: Vector3, matrixWorld: Matrix4

• tap - count: number, position: Vector3, matrixWorld: Matrix4

• swipe - direction is either 'up' or 'down'

• pan - delta: Vector3 distance, state - start, update, end

The following gestures require a device that detects two finger movements

• pinch - delta: pinch time, scale: pinch scale, state - start, update, end
• rotate - theta - angle in radians, state - start, update, end
