Abstract
Examples are disclosed that relate to computing devices and methods for simulating light passing through one or more lenses. In one example, a method comprises obtaining a point spread function of the one or more lenses, obtaining a first input raster image comprising a plurality of pixels, and ray tracing the first input raster image using the point spread function to generate a first output image. Based on ray tracing the first input raster image, a look up table is generated by computing a contribution to a pixel in the first output image, wherein the contribution is from a pixel at each location of a subset of locations in the first input raster image. A second input raster image is obtained, and the look up table is used to generate a second output image from the second input raster image.
