Abstract
Embodiments provide for the rendering of illumination effects on real-world objects in augmented reality systems. An example method generally includes overlaying a shader on the augmented reality display. The shader generally corresponds to a three-dimensional geometry of an environment in which the augmented reality display is operating, and the shader generally comprises a plurality of vertices forming a plurality of polygons. A computer-generated lighting source is introduced into the augmented reality display. One or more polygons of the shader are illuminated based on the computer-generated lighting source, thereby illuminating one or more real-world objects in the environment with direct lighting from the computer-generated lighting source and reflected and refracted lighting from surfaces in the environment.
