What is the standard frame rate of computer animation?
There is no standard frame rate for computer animation
3 of 48
For what reasons is animation perceived as motion?
An image remains in the eye chemically for a brief time. The human mind has a need to conceptually complete a perceived action. A sequence of images is read as a continuous motion.

Define Kinematics
The study of the movement of structures connected with joints.
5 of 48
Define Tweening
Generating key frames to give the appearance that the first image evolves into the second.
6 of 48
Define Orthographics
2D drawing of a 3D object
7 of 48
Name vector drawn objects
Lines. Circles. Cubes.
8 of 48
Name a not vector drawn object
Photographs

What are Orthographic projections used for?
Engineering - as a means to produce object dimensions that are unambiguous. Each line of 1 unit length will have the same length everywhere on the drawing.
23 of 48
Define Perspective projection
Lines of identical real-world lengths appearing different due to foreshortening.
24 of 48

25 of 48
Describe 3D
Has length, width and depth, resulting in volume. Measured in cubic units.
26 of 48
Define Boolean
An object created by combing two objects using mathematical operators.
27 of 48
What is a vertex?
A point where two or more lines, curves or edges meet.
28 of 48
What is an edge?
A line joining two vertices.
29 of 48
What is a face?
A surface formed by three or more points.
