Question: What is meant by the term projection?
A
The process of mapping three dimensional images to two dimensions for display.

B
An interpolation technique used to remove texture distortion, stair casing, or jagged edges at the edges of an object.

C
The part of the graphics engine that draws 3-D primitives, usually triangles or other simple polygons.

D
Wrapping a texture image onto an object to create a realistic representation of the object in 3D space.

Question: What is meant by the term rigging?
A
A combination of colors that appear to have a stronger impact and highly visible look.

B
The area of the graphics memory used to store the Z or depth information about rendered objects.

C
The process of linking a 3-D object, such as modeling a character, to its bone structure (skeletal animation).

D
The process of applying a texture to the surface of 3-D models to simulate walls, sky, etc.

Question: What does the term "constraint" imply?
A
A graphics processing technique that simulates transparency or translucency for objects in a 3D scene to create visual effects like smoke, glass, or water.

B
The section of the graphics memory that stores the stencil data.

C
A rule or condition that must be followed regarding how the individual objects within an graphic can or cannot move, such as a wrist having to be attached to both a hand and an end of the lower arm.

D
Memory that is dedicated to the graphics processor and used to store rendered pixels before they are displayed on the monitor.

Question: What is meant by the term fog?
A
The mixing of an image with a fixed color that thickens as the image's pixels get further away from the viewpoint.

B
A special type of channel used in graphics software for saving selections.

C
a technique of blending bitmap-based images and text to reduce the stair-stepping or jagged appearance.

A
First rotation, then translation, and then scaling.

B
First scaling, then rotation, and then translation.

C
First translation, then scaling, and then rotation.
