• C) Ambient
• D) Diffuse

A polygon is usually defined by a sequence of vertices and ------------------

• A) Points
• B) Ending lines
• C) Vertices
• D) Edges

In the Phong reflection model, there are 3 constants (a, b, c) which are used to describe the qualities of which of the following phenomena?

• A) The amount to perturb reflection vectors as they are mirrored across the normal
• B) The attenuation of a point light source with distance
• C) The material reaction to ambient, diffuse and specular light respectively
• D) The size (in each dimension) which the light is assumed to have

_____________ projection is obtained by projecting points along parallel lines that are not perpendicular to projection plane.

• A) Oblique
• B) Perpendicular
• C) None of the given
• D) Orthographic

Ambient light is the light that comes from ----------------------directions, thus all surfaces are illuminated equally regardless of orientation.

• A) Two
• B) Zero
• C) One
• D) Three

A parametric curve is one whose defining equations are given in terms of a -------------, common, independent variable called the parametric variable.

• A) Triple
• B) None of the given
• C) Single
• D) Double

We allow the parametric variable to take on values only in the interval ----------------.

• A) -1 <= u <= 1
• B) -1 <= u <= 0
• C) 0 <= u <= 2
• D) 0 <= u <= 1

The reflected light wave turns out to be a / an ______________ case since light is reflected at the same angle as the incident wave (when the surface is smooth and uniform, as we'll assume for now).

• A) Two
• B) Six
• C) Three
• D) Nine

--------- is the change in the direction of a light ray when it bounces off the boundary between two media.

• A) Reflection
• B) Diffusion
• C) Refraction
• D) Shadow

The ________________ functions multiply the current matrix by a rotation matrix.

• B) Yes
• C)
• D)

• B) Separate
• C) Opposite
• D) Similar
