By using two axes, a plane is determined: for example, the xy plane is defined by placing the x and y axes so that they intersect at the global centre (point of origin). Images become distorted if forced into a different aspect ratio during enlargement, reduction, or transfers.Īxis, axes A straight line indicating the origin and direction of an object in space. Articulated chains are used to animate objects and are invisible to the renderer.Īspect ratio The ratio of height to width of a rectangular area such as a screen, window, or pixels. It is also called a kinematic chain because it uses inverse kinematics. This is done by a mathematical process that subsamples pixels.Īrticulated chain A hierarchy composed of a chain root, a number of joints, and an end effector.
In SOFTIMAGE|3D, almost any element or parameter can be animated.Īntialiasing A method of smoothing out and sharpening rough or fuzzy edges of graphics to produce a more polished look. Also, the process of creating and recording images that change over time. Also used to describe the strength of deformation (envelope) in the Actor module.Īnimatics Preliminary animated versions of a final video or film presentation.Īnimation The movement of elements through time and space. Other channels or components are Red, Green, and Blue.Īmbient A term used to describe the lighting or illumination in a scene which is assumed to come from any direction and is thus independent of the presence of objects, the viewer position, or the actual light sources in the scene.Īmplitude Typically describes the strength of an electronic signal, measured by its waveform’s height. The alpha component is typically output as a separate component signal. It specifies the transparency of each pixel, allowing portions of one image to show through another when they are overlaid. Aliasing is caused by limited display resolution.Īlpha channel The alpha channel is one of the four channels (or components) of information with each pixel of an image. These effects include staircasing along diagonal lines, moire effects in checkerboards, and temporal aliasing (strobing) in animated scenes. The results of adaptive supersampling are slightly more localized than a Barlett filter, and the computing time is often shorter.Īlgorithm A rule or procedure for solving a mathematical problem that usually involves repeating an operation.Īliasing “Jagged” images created by unfiltered angled lines being presented upon the raster lines. See Articulated chains and Inverse kinematics.Īdaptive supersampling A way of antialiasing the surface of an object by decreasing the oversampling rate for those pixels that do not require the oversampling. A concept used in modelling and animation in which shapes are defined in terms of three axes (x, y, and z) used to represent width, height, and depth, respectively.Īctor A term often used for an animated character.Īctor is also the module in SOFTIMAGE|3D that lets you create characters made from articulated chains. The following is a glossary of terms used in SOFTIMAGE.ģD Three dimensional.
