Graphics and Computers

The document provides a comprehensive overview of computer graphics, detailing its importance across multiple sectors such as entertainment, engineering, medicine, and information technology. It begins by defining computer graphics as the art and science of visual communication through computer displays and interaction devices. The text emphasizes the dual direction of communication: from computer to human and vice versa, mediated by various input devices like keyboards, mice, and touchscreens.

The introduction outlines the foundational elements of computer graphics, including the mathematical and physical principles that govern light modeling and animation. It explains how graphics programs are designed to effectively communicate visual information, relying on disciplines such as mathematics, physics, human perception, and graphic design. The document also discusses the process of rendering, which involves creating images from geometric models by simulating how light interacts with surfaces.

The text highlights the evolution of user interfaces, particularly the graphical user interface (GUI), which has transformed how users interact with computers and devices. It notes the shift from 2D to 3D interfaces, describing the emergence of hybrid interfaces that combine elements of both dimensions. The document emphasizes the growing expectations of users for more immersive and interactive experiences, driven by advancements in technology and the increasing prevalence of graphics in everyday life.

Furthermore, the document addresses the role of organizations like SIGGRAPH in promoting research and development in computer graphics. It discusses the impact of graphics on various applications, including video games, film, architecture, and data visualization. The text concludes by reflecting on the future of computer graphics, suggesting that as technology continues to advance, the integration of graphics into various fields will only deepen, enhancing user experiences and expanding the possibilities for visual communication.
