1. A method to facilitate processing video bit stream data, comprising estimating relative location and intensity of light sources in a 360° six degrees of freedom (6 DoF) scene, including:
generating point clouds from the 6 DoF scene;
computing surface normals, determining whether light intensity peaks for objects in the 6 DoF scene are higher than a predetermined threshold difference; and
performing light estimations for each object upon a determination that the light intensity peaks are higher than a predetermined threshold difference.
