Supposing we wish to find the matrix that represents the reflection of any point (x, y) in the x-axis.The transformation involved here is one in which the coordinates of point (x, y) will be transformed from (x, y) to (x, -y).For this to happen, x does not change, but y must be negated.We can therefore achieve the required transformation by multiplying y by minus one (-1). For example, if the x-, y- and z-axis are scaled with scaling factors p, q and r, respectively, the transformation matrix is: Shear The effect of a shear transformation looks like ``pushing'' a geometric object in a direction parallel to a coordinate plane (3D) or a coordinate axis (2D).
