COMPUTER GRAPHICS PROGRAMMING - FINALS EXAM

It refer to images applied to surfaces of geometric shapes in three- dimensional scenes

Textures

It specifies what part of the texture image to sample from

texture coordinate

The process of retrieving the texture color using texture coordinates

sampling

It is a collection of texture images where each subsequent texture is twice as small compared to the previous one

mipmap

It is a data structure that stores pixel data from an image

texture object

It refers to the placement of lights in a scene to achieve a desired effect

Lighting

It affects all points on all geometric surfaces in a scene by the same amount

Ambient lighting

It represents light that has been scattered and thus will appear lighter or darker in various regions, depending on the angle of the incoming light

Diffuse lighting

It creates bright spots and highlights on a surface to simulate shininess, which is the tendency of a surface to reflect light

Specular lighting

It is a combination of lighting types used to determine the color at each point on a surface

illumination model

It uses ambient, diffuse, and specular lighting, and is particularly appropriate for reflective or shiny surfaces

Phong model

the direction vector of the light ray and a vector perpendicular to the surface

normal vector

It simulates rays of light emitted from a single point in all directions and incorporates attenuation

point light

It is the decrease in intensity as the distance between the light source and the surface increases

Attenuation

It simulates a distant light source, such as the sun, in which all the light rays are oriented along the same direction, and there is no attenuation

directional light

When using lights, the colors on a surface may be brighter or dimmer, depending on the angle at which the light rays meet the surface

Shading

These are areas hidden from the light source

Shadows

The data required for creating shadows will be gathered in a rendering pass

shadow pass

One technique to implement shadows which the scene is rendered from the light's point of view

shadow mapping
