How does ‘real-time lighting’ differ from ‘baked lighting’ in VR?

• A. Real-time lighting is dynamic, while baked lighting is pre-calculated
• B. Real-time lighting requires more memory than baked lighting
• C. Baked lighting is used primarily for mobile VR applications
• D. Real-time lighting produces lower quality visuals than baked lighting

Answer: (A)

Real-time lighting is characterized by its dynamic nature, meaning that it can change in response to user interactions, movement, or changes in the environment within the virtual reality experience. This allows for a more immersive experience, as the lighting can adapt in real-time to the action taking place, creating shadows and highlights that enhance realism. On the other hand, baked lighting involves pre-calculating the lighting information and storing it in textures. This process is done before runtime, which can save computational resources during gameplay but limits flexibility. The baked lighting provides static light and shadow information that doesn't change with the scene or user actions. This method is often used for scenes where the lighting does not need to change, thereby improving performance, especially in environments with limited processing power, such as mobile VR. By highlighting how real-time lighting allows for dynamic and interactive environments compared to the static nature of baked lighting, it becomes clear why the distinction is essential for VR developers.
