3D Animation and Visual Effects

Animation is a method in which pictures are manipulated to appear as moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film. Today, most animations are made with computer-generated imagery (CGI). Computer animation can be very detailed 3D animation, while 2D computer animation can be used for stylistic reasons, low bandwidth 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 animation is achieved by a rapid succession of sequential images that minimally differ from each other. The illusion—as in motion pictures in general—is thought 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 phenakisticope, zoetrope, flip book, praxinoscope and film. Television and video are popular electronic animation media that originally were analog and now operate digitally. For display on the computer, techniques like animated GIF and Flash animation were developed.

Animation is more pervasive than many people realise. Apart from short films, feature films, animated gifs and other media dedicated to the display of moving images, animation is also heavily used for video games, motion graphics and special effects. Animation is also prevalent in information technology interfaces.

The physical movement of image parts through simple mechanics – in for instance the moving images in magic lantern shows – can also be considered animation. The mechanical manipulation of puppets and objects to emulate living beings has a very long history in automata. Automata were popularised by Disney as animatronics.

 

Visual effects (abbreviated VFX) is the process by which imagery is created or manipulated outside the context of a live action shot in film making.

Visual effects involve the integration of live-action footage (special effects) and generated imagery (digital effects and/or optical effects) to create environments, inanimate objects, animals and/or creatures which look realistic, but would be dangerous, expensive, impractical, time consuming or impossible to capture on film. Visual effects using computer-generated imagery (CGI) have recently become accessible to the independent filmmaker with the introduction of affordable and easy-to-use animation and compositing software.

Visual effects are often integral to a movie's story and appeal. Although most visual effects work is completed during post-production, it usually must be carefully planned and choreographed in pre-production and production. While special effects such as explosions and car chases are made on set, visual effects are primarily executed in post-production with the use of multiple tools and technologies such as graphic design, modeling, animation and similar software. A visual effects supervisor is usually involved with the production from an early stage to work closely with production and the film's director design, guide and lead the teams required to achieve the desired effects.

Many studios are specialized in the field of visual effects areas, among which: Digital Domain, DreamWorks Animation, Framestore, Weta Digital, Industrial Light & Magic, Pixomondo and Moving Picture Company.
