Rendering techniques are used to create realistic images from abstract models. They include techniques like ray tracing, radiosity, and global illumination.

Shading: The process of adding color and texture to 3D objects, giving them a more realistic appearance.
Lighting: The use of different lighting techniques to illuminate 3D objects and create a sense of depth and volume.
Ray tracing: A rendering technique that simulates the behavior of light as it travels through different materials.
Radiosity: A lighting technique that calculates the distribution of light in a scene based on the surfaces of objects.
Texture mapping: Applying a 2D image or texture to a 3D object to create the illusion of surface detail and realism.
Global illumination: A set of algorithms that simulate light interactions in a 3D scene to create a more realistic look and feel.
Rendering engines: The software used to generate and display 3D objects and scenes.
Anti-aliasing: A technique used to smooth out jagged edges and improve the overall visual quality of a rendered image.
Asset creation: The process of creating 3D models, textures, and other assets used in rendering.
Real-time rendering: The ability to generate and display 3D graphics in real-time, as opposed to rendering a still image or video sequence.
Shadows: The use of shadows to create depth and realism in a rendered scene.
Ambient occlusion: A shading technique that simulates the way that light interacts with the environment, creating a more believable scene.
Depth of field: A rendering effect that blurs objects in the foreground or background, creating a sense of depth and realism.
Motion blur: A rendering effect that blurs moving objects to create the illusion of motion.
Particles and effects: The creation of 3D particle systems and special effects, such as explosions, smoke, and water.
Ray tracing: A rendering technique that simulates the behavior of light as it interacts with objects in a scene, producing photorealistic images.
Radiosity: A technique that models indirect illumination by computing the distribution of light between surfaces in a scene. This method is commonly used in architectural visualization.
Global illumination: A method that accounts for the complex way in which light bounces off surfaces, resulting in more accurate representations of lighting effects.
Photon mapping: A technique that generates a map of photons in a scene that interact with objects to create realistic lighting effects.
Ambient occlusion: A method that calculates the degree to which a surface is occluded or hidden from direct lighting, resulting in a more realistic representation of shading in a scene.
Path tracing: A rendering method that traces the path of light rays from the camera through the scene, accounting for global illumination effects and reflections.
Volume rendering: A technique used to visualize three-dimensional data sets, such as medical scans or scientific data, by modeling the interaction of light with a volume of data.
Texture mapping: A method that applies a 2D image or pattern to a 3D object to simulate surface properties such as color, reflectivity, and texture.
Non-photorealistic rendering (NPR): A technique that creates images that do not attempt to look realistic, but instead mimic the look of hand-drawn or painted artwork.
Displacement mapping: A technique that alters the geometry of a 3D mesh to add more detail, typically by using a grayscale image to displace the vertices of the mesh.
Motion blur: A method that simulates the effect of motion in an animation by blurring objects in motion, giving the illusion of speed or motion.
Depth of field: A rendering technique that simulates the way in which a camera focuses on objects at certain distances, resulting in a more natural look to the image.
Cartoon shading: A shading technique that simulates the shading of a cartoon or comic book, typically featuring bold outlining and flat shading.
Subsurface scattering: A method used to simulate the way in which light scatters through translucent or semi-translucent materials, such as skin or wax.
Cell shading: A technique used to give 3D objects a stylized, hand-drawn look, typically featuring solid colors and thick outlines.
Soft shadows: A rendering technique that simulates the way in which shadows are diffused by light sources, resulting in more realistic-looking shadows.
Caustics: A method that simulates the patterns of light created by reflections and refractions, such as the patterns seen at the bottom of a swimming pool.
Ambient inclusion: A technique that calculates the amount of ambient light in a scene, resulting in a more natural-looking render.
"The resulting image is referred to as the render."
"The scene file contains geometry, viewpoint, texture, lighting, and shading information describing the virtual scene."
"The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file."
"The term 'rendering' is analogous to the concept of an artist's impression of a scene."
"It is the last major step in the graphics pipeline, giving models and animation their final appearance."
"Rendering has uses in architecture, video games, simulators, movie and TV visual effects, and design visualization."
"A renderer is a carefully engineered program based on multiple disciplines, including light physics, visual perception, mathematics, and software development."
"A GPU is a purpose-built device that assists a CPU in performing complex rendering calculations."
"The rendering equation does not account for all lighting phenomena, but instead acts as a general lighting model for computer-generated imagery."
"Pre-rendering is a slow, computationally intensive process that is typically used for movie creation, where scenes can be generated ahead of time, while real-time rendering is often done for 3D video games and other applications that must dynamically create scenes."
"3D hardware accelerators can improve real-time rendering performance." Quotes are not available for the remaining questions as they require clarification. Please specify the questions further for me to provide appropriate quotes.
