Rendering is the process of generating a final image or animation from a 3D model using computer software. This involves taking the digital representation of objects, textures, and lighting, and transforming them into a visually appealing picture. Artists and designers use rendering to create realistic scenes for movies, video games, and architectural visualizations, making it an essential part of the creative process. There are different types of rendering techniques, such as real-time rendering used in video games, which allows for quick image generation, and ray tracing, which produces high-quality images by simulating how light interacts with objects. Each method has its own advantages, depending on the desired outcome and the resources available.
