What are Lights in Spatial Computing?
In augmented reality (A/R), virtual reality (V/R) and mixed reality (M/R), the term "light" (plural: "lights") refers to how a node illuminates a 3D model, space or region within a scene.
An example of a point light illuminating a red cube.
Lights are elements that illuminate objects, geometries, models or environments within a scene.
The presence of light alters the appearance of materials and textures that use physically based rendering (PBR).
Computing software development kits such as ARKit, SceneKit, ARCore, ViroCore or 3JS offer out of the box lights.
