3D Model Rendering

3D model rendering is the process of converting 3D models into 2D images on a computer. It is the final step in the process of 3D visualization, which involves creating models of objects, texturing those objects, and adding lighting to the scene.

Rendering is often compared to taking a photo or filming the scene after the setup is finished in real life. The final 2D image may include photorealistic effects or non-photorealistic styles. Different methods are better suited for either photorealistic rendering or real-time rendering.

In real-time rendering, the goal is to show as much information as possible as the eye can process in a fraction of a second. This is the basic method employed in games, interactive worlds, and VRML. The rapid increase in computer processing power has allowed a progressively higher degree of realism even for real-time rendering.

In summary, 3D rendering is a crucial part of the 3D visualization process that allows us to create realistic or stylized 2D images from 3D models. It's widely used in various fields such as video games, virtual reality, and computer-aided design.
