Abstract: Methods for determination of AR lighting with dynamic geometry are disclosed. A camera pose for a first image comprising a plurality of pixels may be determined, where each pixel in the first image comprises a depth value and a color value. The first image may correspond to a portion of a 3D model. A second image may be obtained by projecting the portion of the 3D model into a camera field of view based on the camera pose. A composite image comprising a plurality of composite pixels may be obtained based, in part, on the first image and the second image, where each composite pixel in a subset of the plurality of composite pixels is obtained, based, in part, on a corresponding absolute difference between a depth value of a corresponding pixel in the first image and a depth value of a corresponding pixel in the second image.
