Introduction                                                                                          

The term Transformation is generally referred to as converting a graphic into another graphic by applying some rules or algorithms. Sometimes an image or picture can be a combination of lines, rectangle, circle, and triangle. If we draw the basic and combination of pictures, then there should be a need to transform these images. Now we can perform the following actions to transform the images-

  • We can change the position of an image.
  • We can increase or decrease the size of an image.
  • We can change the angle of the image.

By using the above actions, we will find a new image; this process is called Transformation. We can use some algorithms to produce new pictures.

 The object transformation includes two important points-

  • Geometric Transformation: When we are moving the picture, and the background is fixed, then it is a Geometric Transformation.
  • Coordinate Transformation: When we are moving the background, and the picture is fixed, then it is Coordinate Transformation.

Types of Transformation

Transformation

There are two basic kinds of Translation.

1.Two-Dimensional(2D) Transformation:

When we translate, rotate, and scale object in the two-dimensional plane, then it is called a Two-Dimensional Transformation.” A two-dimensional plane consists of the x and y-axis.

The Two-Dimensional Transformation includes-

  • 2D Translation: “Translation is a mechanism used to move the object from one position to another position on the screen.
  • 2D Rotation: “Rotation is a process used to rotate the object from origin to a particular angle.
  • 2D Scaling: Scaling is a process or technique used to resize the object in two-dimensional plane.
  • 2D Reflection: “Reflection is a mechanism or process in which we can rotate the object at the angle of 180°”.
  • 2D Shearing: “Shearing is a process that is used to perform slanting on the object. It is also called “Skewing.”

2.Three-Dimensional Transformation:

When we translate, rotate, and scale object in the three-dimensional plane then, it is called Three-Dimensional(3D) Transformation”. A threedimensional plane consists of x, y, and z-axis.

The Three-Dimensional Transformation includes-

  • 3D Translation: “Translation is a mechanism used to move the object from one position to another position on the three-dimensional plane.
  • 3D Rotation: “Rotation is a process used to rotate the object from origin to a particular angle in three-dimensional plane.
  • 3D Scaling: “Scaling is a process or technique used to resize the object in three-dimensional plane”.
  • 3D Reflection: “Reflection is a mechanism or process in which we can rotate the object at the angle of 180° in three-dimensional plane.
  • 3D Shearing: “Shearing is a process that is used to perform slanting on the object. It is also called “Skewing”. It also includes z-axis.
