    if ( a.count !== b.count || a.itemSize !== b.itemSize ) {

        return false;

    }

    for ( let i = 0, il = a.count * a.itemSize; i < il; i ++ ) {

        const delta = Math.abs( a.array[ i ] - b.array[ i ] );
        if ( delta > tolerance ) {

            return false;

        }

    }

    return true;
