Specularity
From Wikipedia, the free encyclopedia
Specularity is the quality used in many 3D rendering programs to set the size and the brightness of a texture's reflection to light.
Adding specularity into a render allows one to add highlights to an object.
Specularity only provides an illusion of reflection to the light. The function of specularity only provides a central hotspot and the halo surrounding it.
In some situations, specularity is preferred over reflection because of faster render speeds (due to the complexity of raytracing in reflection algorithms) and because, even though reflection mapping is more realistic, specularity algorithms often appear more realistic.
