    What the SceneLoader hands each commit*Geometry helper.

    interface GeometryCommitHost {
        rootGroup: Group<Object3DEventMap> | null;
        gpuBufferPool: GPUBufferPool | null;
        depthSort: DepthSortCoordinator | null;
    }
    Index
    rootGroup: Group<Object3DEventMap> | null

    The loader's scene root; the committed node is looked up by name under it.

    gpuBufferPool: GPUBufferPool | null

    The pooled-geometry path, when the loader runs one.

    depthSort: DepthSortCoordinator | null

    The host's depth-sort coordinator, which every non-noop commit reports to (noteCommit). null leaves the node untracked: no back-to-front ordering and no cross-node renderOrder.
