In animation, a type of constraint that keeps an object aimed toward another object. See also constraint.
Industry:Software
In animation, the direction a constrained object must point toward so that it points at the target point.
The aim vector starts at the constrained object’s pivot point, and is defined relative to the object’s local space. By itself, the aim vector does not completely constrain the object, because it does not control the orientation of the object (determined by the up vector and the world up vector).
Industry:Software
In dynamics, a method of simulating the effects of moving air. As the animation plays, the air field affects the motion of objects connected to it.
Industry:Software
A rule or procedure for solving a mathematical problem that frequently involves the repetition of an operation.
Industry:Software
Unwanted visual effects or artifacts caused by limited display resolution. These effects include grainy surfaces, jaggies (staircasing along diagonal lines), moiré effects (grids or checkerboards), or temporal aliasing (strobing) in animated scenes. They are controlled by anti-aliasing settings.
Industry:Software
A view of an image that represents the presence and degree of opacity of objects. The channel associated with each pixel determines the degree of opacity of that pixel.
In an alpha channel, areas that do not contain objects are black, areas that contain solid objects are white, and areas that contain partially transparent objects are a shade of gray.
In video production, the alpha channel is used to determine how one video image is laid over another.
Industry:Software
A Maya ambient light combines both an ambient light and a diffuse light. The diffuse portion has a source location and a uniform spherical distribution, while the ambient portion appears to come from everywhere, and is often used as a fast approximation of indirect lighting. Ambient light is typically used to control the overall brightness and color of a scene.
Use an ambient light to simulate a combination of direct light (for example, a lamp) and indirect light (lamp light reflected off the walls of a room).
Industry:Software
In photography, the measure of the angle of a lens' view. As you adjust a camera’s focal length, the angle of view narrows and expands, causing objects to get larger or smaller in the frame.
In Maya, the angle of view is simulated by zooming the camera.
Industry:Software
The unit of measure for operations that use an angular value (for example, rotation). The default unit for measuring angular values is degrees.
