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
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
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.
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 ...
The problem is easily spotted in a rendering which ought to have a specular highlight moving smoothly across the surface of a model as it rotates. Gouraud shading will instead produce a highlight continuously fading in and out across neighboring portions of the model, peaking in intensity when the intended specular highlight aligns with a ...
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 ...
Phong shading assumes a smoothly varying surface normal vector. The Phong interpolation method works better than Gouraud shading when applied to a reflection model with small specular highlights such as the Phong reflection model. The most serious problem with Gouraud shading occurs when specular highlights are found in the middle of a large ...
Specular gloss; Distinctness of image gloss; Sheen; Reflection haze, H (for a specified specular angle), the ratio of flux reflected at a specified angle (or angles) from the specular direction to the flux similarly reflected at the specular angle by a specified gloss standard.
