injectBeforeRender()​

A shortcut to register a before render callback

@Component({
    /*...*/
})
export class SceneGraph {
    readonly sub = injectBeforeRender(() => {}, 0);
}
info

injectBeforeRender() automatically cleans up the before render but it returns the reference to the clean up function. We can call this function anytime to clean up the before render, not just in ngOnDestroy

is.ref(a); // checks if a value is ElementRef
is.object3D(a); // checks if a value is an instance of THREE.Object3D
// and more
