WebRim lighting is a light that usually comes from beside or behind a subject, and enhances its silhouette. This shader fakes this by making use of the Fresnel effect. This can be used to stylize or highlight objects, and it greatly favors certain artstyles. It is especially pleasing when applied to smooth curvy models. WebThe OpenGL light model presumes that the light that reaches your eye from the polygon surface arrives by four different mechanisms: AMBIENT - light that comes from all directions equally and is scattered in all directions equally by the polygons in your scene. phits totfact

WebOpenGL Lighting By default, OpenGL's fixed-function pipeline implements the Blinn-Phong Shading Model. – Originally from Bui Tuong Phong's Ph.D work at the University of Utah (1973). – Modified by James F. Blinn (1977). Light is modeled in three categories: ambient, diffuse, and specular.
