Question: Which of the following best describes the term "vertex-vertex polygon mesh?"
A
A process by which color information is interpolated across the face of the polygon to determine the colors at each pixel.

B
A method of using two buffers, one for display and the other for rendering.

C
The simplest mathematical representation of a mesh, but which is not widely used due to the lack of explicit face and edge information.

D
A method of increasing the quality of a texture map by applying different-resolution texture maps for different objects in the same image, depending on their size and depth.

Question: What is meant by the term gradient?
A
A binary representation in which a bit or set of bits corresponds to some part of an object such as an image or font.

B
In computer graphics, a curve that is generated using a mathematical formula which assures continuity with other b-splines.

C
A color (or grayscale) fill that gradually blends from one color to another, perhaps from light to dark, for example.

D
In computer graphics, a technique for simulating rough textures by creating irregularities in shading.

Question: What does the term "spline" imply?
A
In computer-aided design, a smooth curve that runs through a series of given points.

B
The smallest rectangular region of a picture or a frame buffer for which you can specify unique properties such as color and transparency.

C
Simulating a condition or activity by performing a set of equations on a set of data.

D
An interface that allows for the transfer of a digital video signal from a computer to a display, which increases the image quality and performance over a comparable analog system.
