Geometry in computer graphics is crucial for creating realistic and appealing visual representations. By manipulating points, lines, curves, and shapes, geometric algorithms define the structure and layout of objects in a virtual environment. When combined with vectorial computer graphics, which use mathematical equations to render images based on geometric primitives, intricate and lifelike scenes can be generated. Vectors play a key role in determining positions, directions, and transformations of objects, offering precise control over visual elements. Together, geometry and vectorial techniques form the foundation for producing high-quality graphics in various applications, from video games to architectural visualizations.
