Which light is same everywhere in Phong reflection model?
A specular reflection is only a reflection of a light source off of the surface of an object. Therefore the color of that reflected light should be the same than the color of the light emitted by the light source. If the light source emits red light, then the specular highlight should be red.
Which lighting is not dependent on any source?
Ambient light refers to a general level of illumination that does not come directly from a light source. It consists of light that has been reflected and re-reflected so many times that it is no longer coming from any particular direction.
What are the components of the Phong reflection model?
The Phong reflection model in particular describes the light reflected from surfaces or emitted by light sources as the combination of 3 components: diffuse, ambient and specular. The model also requires information about the direction in which a particular surface is facing, provided via vectors called surface normals.
What are the different types of reflection of light?
Types of Reflection 1 Regular Reflection. Regular Reflection can also be referred to as Specular Reflection and is simply understood by using a plane mirror. 2 Diffused Reflection. To explore the meaning of diffused reflection, let us consider reflective surfaces other than mirrors. 3 Multiple Reflection.
What are the different types of illumination models?
Basic Illumination Model Light rays are emitted from light sources and bounce (reflect) in the scene until they reach the eye 5 Local vs. Global Illumination Model • Local –only direct and local interaction of objects with light • Global –all interactions and exchange of light –Can model more effects
Can a single source of light be reflected multiple times?
Multiple Reflection For both regular and diffused reflection of light, a single mirror is used while when we take two mirrors, a single source of light can be reflected multiple times. This type of reflection is only possible when the intensity of the light becomes so low that we cannot see it.
