## What is diffuse lighting computer graphics?

Diffuse. Diffuse lighting (or diffuse reflection) is the direct illumination of an object by an even amount of light interacting with a light-scattering surface. After light strikes an object, it is reflected as a function of the surface properties of the object as well as the angle of incoming light.

## What is diffuse and specular reflection in computer graphics?

The reflection of light can be roughly categorized into two types of reflection: specular reflection is defined as light reflected from a smooth surface at a definite angle, and diffuse reflection, which is produced by rough surfaces that tend to reflect light in all directions (as illustrated in Figure 1).

What is the difference between specular and diffuse reflection?

### What is specular lighting in game programming?

Specular lighting identifies the bright specular highlights that occur when light hits an object surface and reflects back toward the camera. Specular lighting is more intense than diffuse light and falls off more rapidly across the object surface.

### What is meant by specular reflection?

Definition of specular reflection : reflection (as of light by a mirror) at a surface having irregularities small as compared with the wavelength of the incident radiation.

What is specular intensity?

A Specular Lighting Model. Specular light reflection. A light ray that reflects off of a surface at an equal but opposite angle to its incoming angle is called “specular reflection.” We assume that the amount of light reflection is equal to the intensity of the incoming light.

#### What is diffuse reflection in computer graphics Mcq?

Diffuse Reflection : Diffuse reflection occurs on the surfaces which are rough or grainy. In this reflection the brightness of a point depends upon the angle made by the light source and the surface.

#### What are the examples of diffuse reflection?

The correct answer is Reflection on roadway. Diffuse reflection is the reflection of light from a surface where an incident ray is reflected at many angles. For the diffuse reflection, everything we see around us is visible. Examples of diffuse reflections are bicycle reflectors, clothing, paper.

What are some examples of specular reflections?

Examples of specular reflections include a bathroom mirror, the reflections on a lake, and glare on a pair of eyeglasses. Sometimes specular reflections are useful, like in a bathroom, but sometimes they are not, like the glare on your glasses.

## What is specular light in photography?

Specular light: Lighting source very powerful in the center that gradually loses energy toward its extremes. Like a traditional torch. It generates very exposed and bright areas in the subject. Like the lights used in photo calls and interviews. Diffuse light: Lighting source with uniform energy all over its surface.

## What is ambient lighting?

What is ambient light? Creating ambient lighting (also called mood lighting) involves using colour, temperature, and brightness to create a comfortable and even level of light throughout a space. The main sources of ambient lighting are usually ceiling lights, wall-mounted fixtures, or recessed spotlights.

Which is an example of diffuse reflection?

### What are the components of lighting in computer graphics?

Lighting interactions In computer graphics, light usually consists of multiple components. The overall effect of a light source on an object is determined by the combination of the object’s interactions with these components. The three primary lighting components (and subsequent interaction types) are diffuse, ambient, and specular.

### What is the difference between lighting and specular lighting?

Instead, specular lighting creates bright spots on objects based on the intensity of the specular lighting component and the specular reflection coefficient of the surface. Lighting models are used to replicate lighting effects in rendered environments where light is approximated based on the physics of light.

What is decomposition of lighting interactions?

Decomposition of lighting interactions. Diffuse lighting (or diffuse reflection) is the direct illumination of an object by an even amount of light interacting with a light-scattering surface. After light strikes an object, it is reflected as a function of the surface properties of the object as well as the angle of incoming light.

#### What is the difference between lighting techniques and graphics techniques?

While lighting techniques offer flexibility in the level of detail and functionality available, they also operate at different levels of computational demand and complexity. Graphics artists can choose from a variety of light sources, models, shading techniques, and effects to suit the needs of each application.
