Translate a square - 2-d and 3-d transformations, Computer Graphics

Assignment Help:

Example1: Translate a square ABCD along with the coordinates as: A(0,0),B(5,0),C(5,5),D(0,5) via 2 units in x-direction and 3 units in y-direction.

Solution: We can show the square here, in matrix form, by using homogeneous coordinates of vertices as:

The translation factors are, tx=2, ty=3

 The transformation matrix for translation:

Tv=

So new object point coordinates are:

[A'B'C'D'] = [ABCD].Tv

Hence, A'(x'1,y'1)=(2,3)

B'(x'2,y'2)=(7,3)

C'(x'3,y'3)=(7,8) and 

D'(x'4,y'4)=(2,8)
