In Babylon.js, lights play a crucial role in simulating realistic lighting conditions within a 3D scene. They contribute to the overall visual appeal of the scene by affecting how objects are illuminated and how shadows are cast. Lights in Babylon.js interact with materials applied to 3D objects, influencing the way surfaces reflect light. Different types of lights are available to simulate various real-world lighting scenarios. Here's an overview:
Purpose of Lights :
* Illumination : Lights in Babylon.js provide illumination to objects within the scene, affecting their appearance based on the type, intensity, and color of the light sources.
* Shadows : Lights contribute to the generation of shadows, adding depth and realism to the scene. Shadows enhance the perception of spatial relationships between objects.
* Ambient Lighting : Ambient lights simulate indirect illumination, providing a baseline level of brightness to the entire scene. They help prevent completely dark areas and add global illumination.
* Specular Highlights : Certain types of lights, such as point lights and spotlights, contribute to specular highlights on reflective surfaces, creating the appearance of shiny or glossy materials.
