Transformations in Graphics

Introduction of Transformations in Graphics

• Transformations allow for a wide range of creative possibilities in graphics design and animation.

Definition of Transformations in Graphics

• Transformations is a technique used to modify the appearance and position of graphical objects, such as images, shapes, and text. 
• In Graphics, transformation refers to the process of changing the position, size, or orientation of an object or image on a two-dimensional plane.
• Transformations can also be used to create a sense of depth and perspective in 3D graphics by applying different scaling and positioning values to objects based on their distance from the viewer.

Features of Transformations in Graphics

• Each transformation activity is a single entity. It can be denoted by a unique name or symbol.
• It is also possible to combine two or more different transformation techniques to create complex effects and animations in graphics. For example, a rotating and scaling transformation can be used to create a spinning, growing, or shrinking animation.

Types of Transformations in Graphics

• There are several types of transformations that can be applied to graphics. These are – 

1. Translation:

   • Moving an object from one location to another by adding a fixed amount to its coordinates.

2. Rotation:

   • Turning an object around a point or axis, such as a pivot point, to create a new orientation.

3. Scaling:

   • Resizing an object uniformly or non-uniformly along one or more axes.

4. Shearing:

   • Skewing is the shape of an object along one or more axes.

5. Reflection:

   • Creating a mirror image of an object across a line or plane.
