CS602-Computer Graphics Quiz  MCQS #Objective #Questions #Finalterm

1. To convert the information in the A matrix into that required for the P matrix, we do some simple matrix algebra. First, we have GP=
NP
UP
NU
UNP ✔
2. With similar expressions for y(u) and z(u). Again the a, b, c and d terms are constant coefficients. As we did with Equation for a plane curve, we combine the x(u), y(u), and z(u) expressions into a single vector equation :
Au2+bu1+cu+d
Au4+bu3+cu2+d1
Au3+bu2+cu2+d
Au3+bu2+cu+d ✔
3. NURBS stands for __
Non-Universal Rational Binary Spline
Non-Uniform Rational Binary Splines
Non-Uniform Rational Beta Splines ✔
Non-Universal Rational Beta Splines
4. An independent consortium, the OpenGL Architecture Review Board, guides the OpenGL specification. With broad industry support, OpenGL is the only truly open, vendor-neutral, ___ graphics standard.
Tertiary
Binary
Single platform
Multiplatform ✔
5. A space curve is not confined to a plane. It is free to twist through space. To define a space curve we must use parametric functions that are ____
Binary Polynomials
Mono Polynomials
Cubic Polynomials ✔
6. ___ sets the reshape callback for the current window. The reshape callback is triggered when a window is reshaped
glutMainLoop
glutIdleFunc
glutReshapeFunc ✔
glutDisplayFunc
7. The reflected light wave turns out to be a ___ 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).
Unknown
Simple ✔
Complex
Abnormal
8. Signed integer colour components, when specified, are linearly mapped to floating-point values such that the most positive representable value maps to 1.0, and the most negative representable value maps to ___.
-1.0
0.0
2.0
1.0✔
Floating-point values are mapped directly.
9. To ensure a smooth transition from one section of a piecewise ___ to the next, we can impose various continuity conditions at the connection points.
non-parametric curve
parametric curve
polygon vector ✔
None
10. If the current matrix (according to glMatrixMode) is multiplied by this translation matrix, with the product replacing the current matrix. That is if M is the current matrix and T is the translation matrix, then M is replaced with ___.
M-T
M+T
M/T
M*T ✔
11. glutReshapeWindow requests a change in the size of the current window. The width and height parameters are size extents in pixels. The width and height must be ___
Neutral
Negative
Positive
None
