Normalized cross product of two vectors on that surface provides real number.

No

Yes

The matrix generated by gluPerspective is multiplied by the current matrix, just as if glMultMatrix were called with the generated matrix. To load the perspective matrix onto the current matrix stack instead, precede the call to gluPerspective with a call to -----------------------. A. gluPerspective B. glRotated C. glTranslated

D. glLoadIdentity

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

B. Single

C. Triple D. None of the given

To ensure a smooth transition from one section of a piecewise __________ to the next, we can impose various continuity conditions at the connection points A. Non of the these

B. parametric curve

C. non parametric curve D. polygon vector _________________ sets the global idle call back to be 'func' so a GLUT program can perform background processing tasks or continuous animation when window system events are not being received. A. glutDisplayFunc

B. glutIdleFunc

C. glutMainLoop D. glutReshapeFunc

While building polygonal model of surfaces, we should use Tintersections. Yes

No

If the current matrix (according to glMatrixMode) is multiplied by the 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 -----------------. A. M+T

B. M*T

C. M/T D. M-T

NURBS stands for -----------------------. A. Non Universal Rational Binary Spline

B. Non Uniform Rational Beta Splines

C. Non Uniform Rational Binary Splines D. Non Universal Rational Beta Splines

Another way to define a space curve by using intermediate points and the tangents at each end for making the curve

Yes

No If we assign a different value to the parametric variable for the intermediate point, then we obtain different values for the coefficients. This, in turn, means that a different curve is produced, although it passes through the -------------- three points. A. Isolate

B. Same

C. None of the given D. Different

Every point on a curve has a straight line associated with it called the

A. tangent line

B. None of the given C. State line D. curved line

A tangent vector certainly defines the slope at one end of the curve, but a vector has characteristics of...... A. direction B. magnitude C. None of the given

D. both direction and magnitude

The mathematics of parametric equation is the basis for ------------- curves. A. Hercules

B. Hermite

C. Tangent D. Bresenham

Imagine a curve in three-dimensional space, each point on the curve has a unique set of coordinates: a specific x value, y value, and z value. Each
