The illumination equation is Blinn-Phong where: pixelColor= Ambient + (Diffuse + Specular) * Shadow ( but let's forget about shadow). Illumination model.ĭetails are added back to the low poly via surface reaction to the light. Once art is done, a low poly model (5000 polygons) is automatically generated along with a normal map.Īt runtime, details are added back by combining the low model with the normal map. BumpMapping allows designers to express their creativity through a 100,000+ polygons creature.
