Abstract
An environment map, such as a cube map, can be obtained for a scene that is appropriate for the current lighting state. A grayscale image representation is generated that represents physical objects visible in the scene. The grayscale representation is provided to a device for rendering AR content. A color lookup table (LUT) is generated for coloring the grayscale image representation. The color LUT can be appropriate for the current lighting conditions of the scene. As the lighting state changes, such as over the course of a day, different color LUTs can be sent to the device for purposes of updating the environment map. The grayscale image representation, once colored, can serve as an environment map for purposes of creating reflection effects on AR content to be rendered with respect to a live view of the scene.
