Question

The matrix representation for scaling in homogeneous coordinates is

(a) P’=S*P

(b) P’=R*P

(c) P’=dx+dy

(d) P’=S*S

The question was asked by my college director while I was bunking the class.

I want to ask this question from Matrix Representations and Homogeneous Coordinates topic in portion 2D Transformation and Viewing of Computer Graphics

Answer 1

The correct answer is (a) P’=S*P

To explain I would say: The matrix representation for scaling is P’=S*P.
