Skeletal Animation
Skeletal animation or rigging is a technique in computer animation in which a character (or other articulated object) is represented in two parts: a polygonal or parametric mesh representation of the surface of the object, and a hierarchical set of interconnected parts (called joints or bones, and collectively forming the skeleton), a virtual armature used to animate (pose and keyframe) the mesh. 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 be used to 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, the set of "bones" may not be hierarchical or interconnected, but simply represent a higher-level description of the motion of the part of mesh it is influencing. The technique was introduced in 1988 by Nadia Magnenat Thalmann, Richard Lape ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Matrix (mathematics)
In mathematics, a matrix (: matrices) is a rectangle, rectangular array or table of numbers, symbol (formal), symbols, or expression (mathematics), expressions, with elements or entries arranged in rows and columns, which is used to represent a mathematical object or property of such an object. For example, \begin1 & 9 & -13 \\20 & 5 & -6 \end is a matrix with two rows and three columns. This is often referred to as a "two-by-three matrix", a " matrix", or a matrix of dimension . Matrices are commonly used in linear algebra, where they represent linear maps. In geometry, matrices are widely used for specifying and representing geometric transformations (for example rotation (mathematics), rotations) and coordinate changes. In numerical analysis, many computational problems are solved by reducing them to a matrix computation, and this often involves computing with matrices of huge dimensions. Matrices are used in most areas of mathematics and scientific fields, either directly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Autodesk Maya
Autodesk Maya, commonly shortened to just Maya (; ), is a 3D computer graphics application that runs on Windows, macOS, and Linux, originally developed by Alias and currently owned and developed by Autodesk. It is used to create assets for interactive 3D applications (including video games), animated films, TV series, and visual effects. History Maya was originally an animation product based on codebase from The Advanced Visualizer by Wavefront Technologies, Thomson Digital Image (TDI) Explore, PowerAnimator by Alias, and ''Alias Sketch!''. The IRIX-based projects were combined and animation features were added; the project codename was Maya. Walt Disney Feature Animation collaborated closely with Maya's development during its production of ''Dinosaur''. Disney requested that the user interface of the application be customizable to allow for a personalized workflow. This was a particular influence in the open architecture of Maya, and partly responsible for its popularity in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Joint Constraints
Joint constraints are rotational constraints on the joints of an artificial system. They are used in an inverse kinematics chain, in fields including 3D animation or robotics. Joint constraints can be implemented in a number of ways, but the most common method is to limit rotation about the X, Y and Z axis independently. An elbow, for instance, could be represented by limiting rotation on X and Z axis to 0 degrees, and constraining the Y-axis rotation to 130 degrees. To simulate joint constraints more accurately, dot-products can be used with an independent axis An axis (: axes) may refer to: Mathematics *A specific line (often a directed line) that plays an important role in some contexts. In particular: ** Coordinate axis of a coordinate system *** ''x''-axis, ''y''-axis, ''z''-axis, common names ... to repulse the child bones orientation from the unreachable axis. Limiting the orientation of the child bone to a border of vectors tangent to the surface of the joint, repu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Ragdoll Physics
Ragdoll physics is a type of procedural animation used by physics engines, which is often used as a replacement for traditional static death animations in video games and Animation, animated films. As computers increased in power, it became possible to do limited real-time physical simulations, which made death animations more realistic. Early video games used manually created animations for a character’s death sequences. This had the advantage of low Central processing unit, CPU utilization, as the data needed to animate a "dying" character was chosen from a set number of pre-drawn frames. In contrast, a ragdoll is a collection of multiple rigid body, rigid bodies (each of which is ordinarily tied to a bone in the graphics engine's skeletal animation system) tied together by a system of constraints that restrict how the bones may move relative to each other. When the character dies, their body begins to collapse to the ground, honouring these restrictions on each of the joint ...

Motion Capture
Motion capture (sometimes referred as mocap or mo-cap, for short) is the process of recording high-resolution motion (physics), movement of objects or people into a computer system. It is used in Military science, military, entertainment, sports, medical applications, and for validation of computer vision and robots. In films, television shows and video games, motion capture refers to recording actions of Motion-capture acting, human actors and using that information to animate Character animation, 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 match moving. In motion capture sessions, movements of one or more actors are sampled many times per second. Whereas early techniques used 3D reconstruction from multiple images, ima ...

Movie Industry
The film industry or motion picture industry comprises the technological and commercial institutions of filmmaking, i.e., film production companies, film studios, cinematography, animation, film production, screenwriting, pre-production, post-production, film festivals, distribution, and actors. Though the expense involved in making film almost immediately led film production to concentrate under the auspices of standing production companies, advances in affordable filmmaking equipment, as well as an expansion of opportunities to acquire investment capital from outside the film industry itself, have allowed independent film production to evolve. In 2019, the global box office was worth . When including box office and home entertainment revenue, the global film industry was worth in 2018.

Video Game Artist
Game art design is a subset of game development involving the process of creating the artistic aspects of video games. Video game art design begins in the pre-production phase of creating a video game. Video game artists are visual artists involved from the conception of the game who make rough sketches of the characters, setting, objects, etc. Bates 2004, p. 171 Bethke 2003, p. 45-49 These starting concept designs can also be created by the game designers before the game is moved into actualization. Sometimes, these concept designs are called "programmer art". After the rough sketches are completed and the game is ready to be moved forward, those artists or more artists are brought in to develop graphic designs based on the sketches. The art design of a game can involve anywhere from two people and up. Small gaming companies tend to not have as many artists on the team, meaning that their artist must be skilled in several types of art development, whereas the larger the company ...
