1. A method of rendering augmented reality content, comprising:

  • obtaining, by a rendering device, a predefined 3D albedo model of an object observed in a physical environment, the predefined 3D albedo model comprising portions corresponding to portions of the object, wherein each portion of the predefined 3D albedo model includes lighting rules selected based on a reflective nature of a corresponding portion of the object;

    deriving, by the rendering device, features from a digital representation of the object;

    obtaining, by the rendering device, augmented reality (AR) content related to the object based on the features;

    deriving, by the rendering device, a pose of the object from the digital representation;

    aligning, by the rendering device, the 3D albedo model with the pose;

    deriving, by the rendering device, observed shading data from the digital representation and the 3D albedo model;

    deriving an estimated object shading model using the 3D albedo model and the observed shading data;

    generating, by the rendering device, environmentally adjusted AR content by applying the estimated object shading model to the AR content; and

    rendering, by the rendering device, the environmentally adjusted AR content.
