Real-time rendering is the process of generating images from 3D models quickly enough to allow for interactive experiences, such as video games and simulations. This technique uses powerful graphics hardware to create visuals on-the-fly, meaning that changes in the scene can be seen immediately by the user. The goal of real-time rendering is to achieve high-quality graphics while maintaining a smooth frame rate, typically 30 to 60 frames per second. Techniques like shading, lighting, and texture mapping are employed to enhance visual fidelity, making the experience more immersive for users.
