Strategies used in Visual effects?

Motion capture: Motion capture (sometimes referred to as mo-cap or mocap, for short) is the process of recording the movement of objects or people. It is used in military, entertainment, sports, medical applications, and for validation of computer vision and robotics. In filmmaking and video game development, it refers to recording actions of human actors and using that information to animate digital character models in 2D or 3D computer animation. When it includes face and fingers or captures subtle expressions, it is often referred to as performance capture. In many fields, motion capture is sometimes called motion tracking, but in filmmaking and games, motion tracking usually refers more to matching moving.Matte painting: A matte painting is a painted representation of a landscape, set, or distant location that allows filmmakers to create the illusion of an environment that is not present at the filming location. Historically, matte painters and film technicians have used various techniques to combine a matte-painted image with live-action footage. At its best, depending on the skill levels of the artists and technicians, the effect is "seamless" and creates environments that would otherwise be impossible or expensive to film. In the scenes the painting part is static and they integrate movements into it.Animation: Animation is a method in which they manipulate figures to appear as moving images. In traditional animation, hand draw or paint images on transparent celluloid sheets to be photographed and exhibited on film. Today, they made most animations with computer-generated imagery. Computer animation can be very detailed 3D animation, while they can use 2D computer animation for stylistic reasons, low capacity or faster real-time renderings. Other common animation methods apply a stop motion technique to two and three-dimensional objects like paper cutouts, puppets or clay figures. Commonly the effect of the animation is achieved by a rapid succession of sequentially thinking the illusion in motion pictures to rely on the phi phenomenon and beta movement, but the exact causes are still uncertain. Analog mechanical animation media that rely on the rapid display of sequential images include the phénakisticope, zoetrope, flipbook, praxinoscope and film. Television and video are popular electronic animation media that originally were analogue and now operate digitally. For display on the computer, it developed techniques like animated GIF and Flash animation.3D modelling: In 3D computer graphics, 3D modelling is developing a mathematical representation of any surface of an object in three dimensions via specialised software. The product is called a 3D model. Someone who works with 3D models may be referred to as a 3D artist. It can be displayed as a two-dimensional image through a process called Something that can physically create the model using 3D printing devices.Rigging: Skeletal animation or rigging is a technique in computer animation in which a character is represented in two parts: a surface representation used to draw the character (called the mesh or skin) and a hierarchical set of interconnected parts (called bones, and collectively forming the skeleton or rig), a virtual armature used to animate (pose and key-frame) the mesh.[9] While this technique is often used to animate humans and other organic figures, it only serves to make the animation process more intuitive, and the same technique can control the deformation of any object such as a door, a spoon, a building, or a galaxy. When the animated object is more general than, for example, a humanoid character, may not be hierarchical or interconnected, but simply represent a higher-level description of the motion of the part of the mesh it is influencing.Rotoscoping: Rotoscoping is an animation technique that animators use to trace over motion picture footage, frame by frame, to produce realistic action. Originally, animators projected photographed live-action movie images onto a glass panel and traced over the image. This device was eventually replaced by computers, but I still called the process rotoscoping. In the visual effects industry, rotoscoping is the technique of manually creating a matte for an element on a live-action plate so something may composite it over another background. Chroma key is more often used for this, as it is faster and requires less work, however, rotoscopy is still used on subjects that aren't in front of a green (or blue) screen, because of practical or economic reasons.Match it related to moving to rotoscope and photogrammetry. Match moving is sometimes confused with motion capture, which records the motion of objects, often human actors, rather than the camera. Typically, motion capture requires special cameras and sensors and a controlled environment. Match moving is also distinct from motion control photography, which uses mechanical hardware to execute multiple identical camera moves. Match moving, by contrast, is typically a software-based technology, applied after the fact to normal footage recorded in uncontrolled environments with an ordinary camera. Match moving is primarily used to track the movement of a camera through a shot so that an identical virtual camera move can be reproduced in a 3D animation program. When new animated elements are composited back into the original live-action shot, they will appear in perfectly matched perspective and therefore appear seamless.Compositing: Compositing is the combining of visual elements from separate sources into single images, often to create the illusion that all those elements are parts of the same scene. Live-action shooting for compositing is variously called "chroma-key", "blue screen", "green screen" and other names. Today, most, though not all, compositing is achieved through digital image manipulation.
