Rendering is the process of generating a visual representation from a 2D or 3D model. In the context of computer graphics, rendering transforms abstract models into realistic images or animations. This involves calculating lighting, shadows, reflections, and other elements to produce a final visual output. The quality and realism of the rendering depend on factors like lighting models, textures, and the sophistication of the rendering engine.

Rendering is crucial in various industries, including animation, architecture, and video game development. High-quality rendering is essential for creating lifelike characters, immersive virtual environments, and realistic architectural visualizations. As technology advances, real-time rendering has gained prominence, enabling interactive and visually stunning experiences.
