Shearing - 2-D and 3-D transformations

Shearing transformations are utilized for altering the shapes of 2 or 3-D objects. The consequence of a shear transformation seems like "pushing" a geometric object in a direction which is parallel to a coordinate plane i.e. 3D or a coordinate axis i.e. 2D. How far a direction is pushed is found by its shearing factor.

One familiar illustration of shear is that seemed when the top of a book is moved associate to the bottom that is fixed on the table. In condition of 2-D shearing, we have two types that are x-shear and y-shear. In x-shear, one can push in the x-direction, negative or +ive, and remain the y- direction that is not changed, whereas in y-shear, individual can push in the y-direction and remain the x- direction fixed.
