Animation and Visual Effects

Natural language processing is not typically used as an HCI technique in computer graphics, as it is more commonly associated with text-based interactions and artificial intelligence.

Cognitive model, mental map, and conceptual model are all terms used to describe the mental model that users develop of a computer graphics system based on their interactions with it.

Educational HCI, learning HCI, and pedagogical HCI are all terms used to describe the process of designing and evaluating HCI for computer graphics applications that are used in educational settings.

Medical HCI, healthcare HCI, and clinical HCI are all terms used to describe the process of designing and evaluating HCI for computer graphics applications that are used in medical settings.

Motion graphics is a technique used to create animated graphics and visual elements, typically for use in marketing, branding, and educational purposes. It is not commonly used in visual effects for film and television productions.

3D modeling is the process of creating realistic digital representations of objects, environments, and characters using specialized software. It forms the foundation for many other aspects of visual effects, such as texturing, animation, and rendering.

Green screen compositing is a visual effects technique used to combine live-action footage with computer-generated elements. It is not a practical effect, which typically refers to physical effects created on set during filming.

Particle systems are used to create realistic simulations of physical phenomena by representing them as a collection of individual particles. This technique is commonly used to create effects such as explosions, water, and fire.

3D modeling is the process of creating realistic digital representations of objects, environments, and characters. It is not a common type of visual effect used in compositing, which typically involves combining live-action footage with computer-generated elements.

3D character modeling is the process of creating realistic digital representations of human characters using specialized software. It involves sculpting the character's form, adding details, and creating textures.

Environmental effects are used to create realistic digital representations of natural phenomena, such as weather, clouds, and fire. These effects help to establish the setting and atmosphere of a film or television production.

Hand manipulation is commonly used to create movement and expressions in glove puppets, allowing the puppeteer to control the puppet's actions and emotions.

There are a number of trends in casting for video games and interactive media, including the increasing use of motion capture technology, the increasing use of voice acting, and the increasing use of diversity in casting. Motion capture technology allows actors to perform their roles in a virtual environment, which can be more efficient and cost-effective than traditional filming methods. Voice acting is becoming increasingly important as video games and interactive media become more immersive and story-driven. Finally, there is a growing trend towards diversity in casting, as casting directors seek to create games and interactive media that are representative of the real world.

Photobashing, texturing, and displacement mapping are all common digital art techniques used for creating realistic textures.

Motion capture involves recording the movements of real actors or objects and translating them into digital animations, providing a realistic and natural look to animated characters.
