2D transformations in computer graphics involve mathematical operations that modify the position, size, and orientation of objects in a two-dimensional space. Key types include translation, rotation, scaling, and shearing, each serving distinct purposes in object manipulation. These transformations are essential for effectively representing and controlling objects in 2D graphics.

Computer Graphics
An Overview

2. Introduction to 2D Transformations
• 2D transformations are mathematical operations that change the
position, size, and orientation of objects in a two-dimensional space.

3. Types of 2D Transformations
• 1. Translation
• 2. Rotation
• 3. Scaling
• 4. Shearing

4. Translation
• Translation moves an object from one location to another in a straight
line.

5. Rotation
• Rotation turns an object around a specified point by a certain angle.

6. Scaling
• Scaling changes the size of an object either by enlarging or reducing it.

7. Shearing
• Shearing shifts the position of an object in one direction, resulting in a
slanted appearance.

8. Conclusion
• 2D transformations are fundamental in computer graphics, allowing
for manipulation and representation of objects in a 2D space.
