- A logic brick that acts like a muscle of a life-form. It can move the object or make a sound.
- Method where RGBA channels are stored as (R, G, B, A) channels, with the RGB channels unaffected by the alpha channel. This is the alpha type used by paint programs such as Photoshop or Gimp, and used in common file formats like PNG, BMP or Targa. So, image textures or output for the web are usually straight alpha.
Method where RGBA channels are stored as (R × A, G × A, B × A, A), with the alpha multiplied into the RGB channel.
Conversion between the two alpha types is not a simple operation and can involve data loss, as both alpha types can represent data that the other cannot though it is often subtle.
Straight alpha can be considered to be an RGB color image with a separate alpha mask. In areas where this mask is fully transparent, there can still be colors in the RGB channels. On conversion to premultiplied alpha, this mask is applied and the colors in such areas become black and are lost.

In general, a resulting image color decomposition, where its (L or Y) luminance channel is separated. There are two different contexts whereas this term is used:
- Refers to the general color decomposition resulting in Y (Luminance) and C (Chrominance) channels, whereas the chrominance is represented by: U = ( Blue minus Luminance ) and V = ( Red minus Luminance ).
- Matte compositing
- Refers to a point in the color gamut surrounded by a mixture of a determined spectrum of its RGB neighboring colors. This point is called Chroma key and this key (a chosen color) is used to create an Alpha Mask. The total amount of gamut space for this chrominance point is defined by users in a circular or square shaped format.
- The coordinates of the primaries on the CIE 1931 xy chromaticity diagram.
- Limits a variable to a range. The values over or under the range are set to the constant values of the range's minimum or maximum.
- Color Gamut
- A gamut traditionally refers to the volume of color a particular color model/space can cover. In many instances, it is often illustrated via a 2D model using CIE Yxy coordinates.
A coordinate system in which a vector represent a color value. By doing so, the color space defines three things:
- A color space that uses the Rec .709 primaries and white point but, with a slightly different transfer function.
Three values often considered as more intuitive (human perception) than the RGB system.
- The Hue of the color.
- Also known as colorfulness, saturation is the quantity of hue in the color (from desaturated -- a shade of gray -- to saturated -- brighter colors).
- The brightness of the color (dark to light).
- Hue, Saturation
- See HSV.

- The light that has a specific direction, but no location. It seems to come from an infinitely far away source, like the sun. Surfaces facing the light are illuminated more than surfaces facing away, but their location does not matter. A Directional Light illuminates all objects in the scene, no matter where they are.
- A method for distorting vertices based on an image or texture. Similar to Bump Mapping, but instead operates on the mesh's actual geometry. This relies on the mesh having enough geometry to represent details in the image.
- Display Referenced
- Refers to an image whose Luminance channel is limited to a certain range of values (usually 0-1). The reason it is called display referenced is because a display cannot display an infinite range of values. So, the term Scene Referenced must go through a transfer function to be converted from one to the other.
- The distance in front of and behind the subject which appears to be in focus. For any given lens setting, there is only one distance at which a subject is precisely in focus, but focus falls off gradually on either side of that distance, so there is a region in which the blurring is tolerable. This region is greater behind the point of focus than it is in front, as the angle of the light rays change more rapidly; they approach being parallel with increasing distance.

- Frame Types
In video compression, a frame can be compressed by several different algorithms. These algorithms are known as picture types or frame types and there are three major types: I, P, and B frames.
- The least compressible but don't require other video frames to decode.
- Use data from previous frames to decompress and are more compressible than I‑frames.
- Use both previous and forward frames for data reference to get the highest amount of compression.

- The process of calculating new data between points of known value, like keyframes.
- The process of determining the movement of interconnected segments of a body or model. Using ordinary Kinematics on a hierarchically structured object you can, for example, move the shoulder of a puppet. The upper and lower arm and hand will automatically follow that movement. IK will allow you to move the hand and let the lower and upper arm go along with the movement. Without IK the hand would come off the model and would move independently in space.
- A property of transparent materials. When a light ray travels through the same volume it follows a straight path. However, if it passes from one transparent volume to another, it bends. The angle by which the ray is bent can be determined by the IOR of the materials of both volumes.
- A frame in an animated sequence drawn or otherwise constructed directly by the user. In classical animation, when all frames were drawn by animators, the senior artist would draw these frames, leaving the "in between" frames to an apprentice. Now, the animator creates only the first and last frames of a simple sequence (keyframes); the computer fills in the gap.

- Manifold meshes, also called water tight meshes, define a closed non-self-intersecting volume (see also non-manifold). A manifold mesh is a mesh in which the structure of the connected faces in a closed volume will always point the normals (and there surfaces) to the outside or to the inside of the mesh without any overlaps. If you recalculate those normals, they will always point at a predictable direction (To the outside or to the inside of the volume). When working with non-closed volumes, a manifold mesh is a mesh in which the normals will always define two different and non-consecutive surfaces. A manifold mesh will always define an even number of non-overlapped surfaces.

'MIP' is an acronym of the Latin phrase 'multum in parvo', meaning 'much in little'. Mipmaps are progressively lower resolution representations of an image, generally reduced by half squared interpolations using anti-aliasing. Mipmapping is the process used to calculate lower resolutions of the same image, reducing memory usage to help speed visualization, but increasing memory usage for calculations and allocation. Mipmapping is also a process used to create small anti-aliased samples of an image used for texturing. The mipmapping calculations are made by CPUs, but modern graphic processors can be selected for this task and are way faster.
See the Mipmap option present in the System Preferences.

Non-Manifold meshes essentially define geometry which cannot exist in the real world. This kind of geometry is not suitable for several types of operations, especially those where knowing the volume (inside/outside) of the object is important (refraction, fluids, booleans, or 3D printing, to name a few). A non-manifold mesh is a mesh in which the structure of a non-overlapped surface (based on its connected faces) will not determine the inside or the outside of a volume based on its normals, defining a single surface for both sides, but ended with flipped normals. When working with non-closed volumes, a non-manifold mesh will always determine at least one discontinuity in the normal directions, either by an inversion of a connected loop, or by an odd number of surfaces. A non-manifold mesh will always define an odd number of surfaces.
- Edges connected to three or more faces (interior faces).
- Vertices belonging to faces that are not adjoining (e.g. two cones sharing the vertex at the apex).

Also used for things like fur, grass or hair.
- Local illumination model that can produce a certain degree of realism in three-dimensional objects by combining three elements: diffuse, specular and ambient for each considered point on a surface. It has several assumptions -- all lights are points, only surface geometry is considered, only local modeling of diffuse and specular, specular color is the same as light color, ambient is a global constant.

- A perspective view is geometrically constructed by taking a scene in 3D and placing an observer at point O. The 2D perspective scene is built by placing a plane (e.g. a sheet of paper) where the 2D scene is to be drawn in front of point O, perpendicular to the viewing direction. For each point P in the 3D scene a PO line is drawn, passing by O and P. The intersection point S between this PO line and the plane is the perspective projection of that point. By projecting all points P of the scene you get a perspective view.
- In an orthographic projection, you have a viewing direction but not a viewing point O. The line is then drawn through point P so that it is parallel to the viewing direction. The intersection S between the line and the plane is the orthographic projection of the point P. By projecting all points P of the scene you get the orthographic view.
