Abstract

Computer graphics have evolved significantly from their earlier forms. They now provide interactivity, enabling users to manipulate object structures using various input devices. The challenge of displaying images of varying sizes on computer screens has been streamlined using computer graphics, which use various algorithms and techniques. Computers are powerful tools for generating and manipulating images on display devices. These processes involve software techniques to create, store, modify, and represent images. Therefore, this study aims to describe how computer graphics provide users with a rich visual experience by focusing on image processing and the different types of transformations used in modeling, such as translation, rotation, dilation, and reflection. Additionally, we designed a questionnaire to investigate the students’ understanding of geometric transformations in computer graphics.
