Issues migrating from @angular-three to angular-three

[IRobot1]

Missing with no obvious replacement
NgtTriple -

position = [0, 0, 0] as NgtTriple`

Radian Pipe -

item.rotation | radian

Ready Event -

(ready)="meshready($event)"

Value of local variable -instance is no

<ngt-mesh #inst (click)="click(inst.instance.value)" >

No documentation for
NgtLoader

  constructor(private loader: NgtLoader) { }
    const s = this.loader.use(TextureLoader, newvalue).subscribe(next => {
      this.texture = next;
    },
      () => { },
      () => { s.unsubscribe(); }
    );

<ngt-color attach="background" color="gray"></ngt-color>

migrates to

<ngt-color attach="background" *args="['gray']"></ngt-color>

I used to be able to do this

<ngt-mesh #inst (click)="this.panelSelected.next(inst.instance.value)">

Looks like inst variable is now an NgtMesh which is extends Mesh. I can't do this, because I get a compile error
TS2345: Argument of type 'NgtMesh' is not assignable to parameter of type 'Object3D'.

<ngt-mesh #inst (click)="this.panelSelected.next(inst)">

Also, I can't do this either, due to a different compile error

<ngt-mesh #inst (click)="this.panelSelected.next(<Object3D><unknown>inst)">

I'm forced to create a function just to handle the type conversion

<ngt-mesh #inst (click)="doclick(inst)">

@Output() panelSelected = new EventEmitter<Object3D>();
doclick(mesh: NgtMesh) {
  this.panelSelected.emit(<Object3D><unknown>mesh)
}

Is there a better way to handle this?
