35 mm slides have the aspect ratio of 4:3 (1.33:1). This tool is so named because it creates arrays of objects (creates an ordered set consisting of multiple copies of the same object).Ī description of the proportion of an image by comparing its width to its height. In a 3D program, the array tool is usually used to create ordered copies of an object within 3D space. This is useful for creating soft shadows with both an umbra (the full shadow) and a penumbra (the partial shadow).Ī set of elements put together into a single entity. The rays emanate from a geometric area instead of a single point (entire surface uniformly emits light). For example, Maya and Blender both offer API's that allow users to automate/write scripts to perform tedious tasks.Ī special kind of point or spotlight. An API can be used to develop new software, like addons for the existing software. The greater the aperture, the smaller the depth of field and the greater the amount of light entering the lens.Īn API is a set of clearly defined methods of communication between various software components. It is achieved by taking the surrounding areas into account when assigning a color value to pixels lying on an object's contour. Through animation the artist’s drawing comes to life.Ī method for blending harsh contours and preventing staircasing or stairstepping. A method of creating the illusion of life or movement in inanimate objects or drawings. Everything in a scene is represented by numeric values and, as such, animation is also the process of changing these values - position, color, or any other property - over time. Also, the process of creating and recording images that change over time. The movement of elements through time and space. Usually, you can tell when this happens because the line between the colors looks very jagged, as if it were a flight of stairs, in fact it is often referred to as a "stairstepping" effect. When referring to pictures, aliasing is the effect that occurs when a line looks jagged instead of smooth because of a contrast in colors. The most common 3D objects are geometric objects, which can be classified according to whether they are polygon meshes, curves, proxy objects, or empties. Some objects have a special role, for instance a camera or a light, while others serve as controls for other objects, for instance armatures, skeletons or splines. Come across a word that you've never seen before? There's a good chance you may find a definition here.Īnything with a position and a representation in 3D space. This page describes some frequently used terms used in 3d Modeling.
