Directional Light
Directional light estimation identifies the direction from which the dominant light source is emanating. This information enables the rendering engine to simulate realistic shadows cast by virtual objects, enhancing the perception of depth and spatial relationships. If a virtual object is placed in a scene with a strong directional light, it will cast a shadow that aligns with the estimated light direction, increasing the realism of the augmentation.
-
Color Temperature
Color temperature estimation assesses the “warmth” or “coolness” of the surrounding light. This allows virtual objects to be rendered with appropriate color tones, ensuring they appear natural within the environment. For example, if the scene is illuminated by warm incandescent lighting, the virtual objects will be rendered with a warmer hue to match the overall color palette.
-
Environmental Textures (Environment Probes)
The framework can capture environmental textures, or “environment probes,” which represent a 360-degree view of the surrounding environment’s lighting and reflections. These textures can then be applied to virtual objects to simulate realistic reflections and refractions, further blurring the line between the virtual and real worlds. Metallic or glossy virtual objects can realistically reflect elements of the surrounding environment, greatly enhancing the visual fidelity of the augmented scene.
These various aspects of light estimation work in concert to create believable and immersive augmented reality experiences.
