# Translation MCQ Questions And Answers

Translation MCQs : This section focuses on "Translation" in Computer Graphics. These Multiple Choice Questions (MCQ) should be practiced to improve the Computer Graphics skills required for various interviews (campus interview, walk-in interview, company interview), placements, entrance exams and other competitive examinations.

1. It is the straight line movement of an object from one position to another is called?

A. Rotation

B. Shearing

C. Scaling

D. Translation

View Answer

Ans : D

Explanation: It is the straight line movement of an object from one position to another is called Translation.

2. The translation pair (Tx,Ty) is called as ?

A. left-shift vector

B. right-shift vector

C. shift vector

D. shear vector

View Answer

Ans : C

Explanation: The translation pair (Tx,Ty) is called as shift vector.

3. Translation is a movement of objects without deformation.

A. TRUE

B. FALSE

C. Can be true or false

D. Can not say

View Answer

Ans : A

Explanation: Translation is a movement of objects without deformation. Every position or point is translated by the same amount. When the straight line is translated, then it will be drawn using endpoints.

4. A translation is applied to an object by

A. Repositioning it along with circular path

B. Repositioning it along with straight line path

C. Both A and B

D. None of the above

View Answer

Ans : B

Explanation: A translation is applied to an object by repositioning it along with straight line path from one location to another.

5. We translate a two-dimensional point by adding

A. X and Y

B. Translation difference

C. Translation distances

D. None of the above

View Answer

Ans : C

Explanation: We can translate 2D point by adding translation distances dx and dy.

6. Which of the following operation can be applied on a 3 D object to move it along any axis from its original position?

A. Shearing

B. Scaling

C. Rotation

D. Translation

View Answer

Ans : D

Explanation: The process of translation is applied to move a point along a specified axis from its original position in the coordinate plane. Translation of a point adds a constant vector to that point to move it from its original place.

7. To change the position of the circle or ellipse its center coordinates are transformed, then the object is drawn using new coordinates.

A. TRUE

B. FALSE

C. Can be true or false

D. Can not say

View Answer

Ans : A

Explanation: True, To change the position of the circle or ellipse its center coordinates are transformed, then the object is drawn using new coordinates.

8. In the equation x1 = dx + x; which part of the equation is called as the translation factor?

A. x1

B. dx

C. x

D. dx+x

View Answer

Ans : B

Explanation: In the equation x1 = dx + x; dx, is the translation factor, i.e. the amount by which the point will be translated. x is the original point. x1 is the coordinate of the point after translation.

9. How many different types of translation are present in computer graphics?

A. 1

B. 2

C. 3

D. 4

View Answer

Ans : C

Explanation: In computer graphics, there are 3 types of translation techniques namely – the point translation (deals with a single point), the line translation (deals with a line) and the polygon translation (deals with a shape).

10. For translating polygon, each vertex of the polygon is converted to a new position.

A. TRUE

B. FALSE

C. Can be true or false

D. Can not say

View Answer

Ans : A

Explanation: True, For translating polygon, each vertex of the polygon is converted to a new position.
