Abstract
A method is performed at an electronic device including one or more processors and a non-transitory memory. The method includes obtaining a first spherical Gaussian (SG) lobe that characterizes ambient light from a physical environment. The method may include determining the first SG lobe based on a 360 degree image of the physical environment. The first SG lobe indicates a first directional characteristic associated with the ambient light. The method includes determining a first plurality of sampling rays based on the first directional characteristic. The method includes obtaining a depth value that is associated with a computer-generated object. The depth value may be from a depth buffer, which is populated with the depth value during rendering of the computer-generated object. The method includes generating a shadow that is associated with the computer-generated object, based on the depth value and a first sampling ray of the first plurality of sampling rays.
