Real-Time Lighting
Real-time lighting is a computer graphics technique that calculates and renders lighting effects dynamically during runtime, allowing for interactive and responsive visual environments in applications like video games, simulations, and VR/AR. It involves techniques such as dynamic shadows, reflections, and global illumination to create realistic or stylized scenes that update instantly based on user input or scene changes. This contrasts with precomputed or baked lighting, which is static and cannot adapt to runtime variations.
Developers should learn real-time lighting to create immersive and visually compelling interactive experiences, particularly in game development, virtual reality, and real-time visualization tools where lighting must respond to dynamic elements like moving objects or changing times of day. It is essential for achieving high-fidelity graphics in modern engines like Unreal Engine or Unity, enhancing realism and user engagement in applications ranging from AAA games to architectural walkthroughs.
