Rendering is the process of generating a visual representation from a model or data set, typically by using computer software. In the context of graphics and web development, rendering refers to the conversion of code, images, or 3D models into a final display on a screen. This process involves interpreting instructions, applying textures, lighting, and effects, and producing the output that users see. Rendering can occur in real-time, such as in video games, or as a pre-processed step, like in animation or architectural visualization.
