Computer-Aided Graphics (CAG) focuses on the use of computer software and tools to create, manipulate, and visualize graphic designs and models. These notes typically cover fundamental concepts like 2D and 3D modeling, transformations, rendering, and the mathematical basis for graphical operations such as geometric transformations and coordinate systems. Topics may include algorithms for line and curve drawing, shading, lighting, texture mapping, and the role of CAD (Computer-Aided Design) in engineering and architectural applications. The notes often explore software like AutoCAD or Blender, along with programming techniques for custom graphic applications, offering practical insights into design, visualization, and problem-solving in modern industries.
