There has been research conducted on the reflection and refraction of light using the ray tracing method and the caustics method as techniques for expressing light in computer graphics. However, there has been very little research conducted on the diffraction of light by the gratings. Authors have uniformly expressed a two-dimensional diffraction grating, simulating Raman-Nath diffraction. We propose diffraction by grating with an arbitrary pattern using the bitmap image as the pattern file.
