Question

We can combine the multiplicative and translational terms for 2D into a single matrix representation by expanding

(a) 2 by 2 matrix into 4*4 matrix

(b) 2 by 2 matrix into 3*3

(c) 3 by 3 matrix into 2 by 2

(d) Only c

I had been asked this question by my school principal while I was bunking the class.

The origin of the question is Matrix Representations and Homogeneous Coordinates topic in chapter 2D Transformation and Viewing of Computer Graphics

Answer 1

Correct answer is (b) 2 by 2 matrix into 3*3

For explanation I would say: We can combine the multiplicative and translational terms for 2D into a single matrix representation by expanding 2 by 2 matrix representation into 3 by 3.
