Computer graphics is about creating, manipulating, and displaying visual images using computers - this includes 2D and 3D images, animation, and simulations.

Key Concepts:

• Rendering: Turning 3D models into 2D images.

• Shaders: Programs that control how pixels are drawn.

• Ray tracing: Simulates realistic lighting by tracing light rays.

• Rasterization: A faster method used in most games.

Algorithms/Mechanisms:

• Z-buffering: Determines which surfaces are visible.

• Polygon mesh algorithms: Used to build 3D models.

• Animation algorithms: Keyframing, motion capture, physics simulation.

Examples of Use:

• Video games and movies

• Augmented reality (AR) and virtual reality (VR)

• Scientific visualisation (e.g., weather patterns, space exploration)

• UI design and simulations in engineering

Key Issues:

• High-quality graphics can demand massive processing power.

• Accessibility—realistic graphics aren't always inclusive (e.g., motion sickness in VR).

• Realism vs. stylisation: Are ultra-real graphics always better?

Human Impact & Perspectives:

• Enhances entertainment, education, communication.

• Can distort reality (deepfakes, unrealistic body images).

• Artists vs. engineers: balancing creativity and technical limits.
