Specular highlights on a pair of spheres. A specular highlight is the bright spot of light that appears on shiny objects when illuminated (for example, see image on right). ). Specular highlights are important in 3D computer graphics, as they provide a strong visual cue for the shape of an object and its location with respect to light sources in the
CG Artists, confused by this term discovered by experimentation that the manipulation of this parameter would cause a reflected highlight from a light source to appear and disappear and therefore misinterpreted "specularity" to mean "light highlights". In fact "Specular" is defined in optics as Optics.
Specular reflection, or regular reflection, is the mirror-like reflection of waves, such as light, from a surface. [ 1 ] The law of reflection states that a reflected ray of light emerges from the reflecting surface at the same angle to the surface normal as the incident ray, but on the opposing side of the surface normal in the plane formed by ...
The specular lighting component gives objects shine and highlights. [13] This is distinct from mirror effects because other objects in the environment are not visible in these reflections. [ 12 ] Instead, specular lighting creates bright spots on objects based on the intensity of the specular lighting component and the specular reflection ...
Specular exponent Controls the glossiness in the Phong shading model. Specular highlights In shading, specular highlight is a bright highlight caused by specular reflections, more prominent on metallic surfaces. These highlights depend on the viewer's position as well as the position of the light source and surface normal. Spline
Catch light or catchlight is a light source that causes a specular highlight in a subject's eye in an image; the term may also refer to the highlight itself. [1] The catch light is either an artifact for a lighting method, or purposely engineered to add a glint or spark to a subject's eye during photography. The technique is effective in both ...
