2D Shearing in Computer Graphics

In this video, we have covered 2D Shearing from Computer Graphics in detail.

What is Transformation?

Transformation is nothing but changing some graphics to another picture by applying rules. It plays an important role in computer graphics to reposition the graphics on the screen and change their size or orientation. 
2D transformation apply on 2D dimensional plane. 

The different types of transformations that are used in computer graphics are: Translation, Scaling, Rotation, Shearing, Reflection.

Shearing: 2D shearing, shears the 2D object size and shape along the x-axis and y-axis. It is the same as sliding the layers in one direction to change the shape of the 2D object.

Shearing is responsible for changing the shape and size of the 2D object along the x-axis, y-axis, or x-y axis. It is the same as sliding the layers of the object in one direction to change its shape. Shearing is an ideal technique to transform the shape of an existing object in a two-dimensional plane.

There are three shear transformations, X-Shear, Y-Shear, and X-Y Shear.

X-Shear: It preserves, the y co-ordinates remain the same but the x co-ordinates change.
Y-Shear: Here x coordinates remain the same but the y coordinates change.
X-Y: Shear: Here both the x and y coordinates change.
