An AR system that leverages a pre-generated 3D model of the world to improve rendering of 3D graphics content for AR views of a scene, for example an AR view of the world in front of a moving vehicle. By leveraging the pre-generated 3D model, the AR system may use a variety of techniques to enhance the rendering capabilities of the system. The AR system may obtain pre-generated 3D data (e.g., 3D tiles) from a remote source (e.g., cloud-based storage), and may use this pre-generated 3D data (e.g., a combination of 3D mesh, textures, and other geometry information) to augment local data (e.g., a point cloud of data collected by vehicle sensors) to determine much more information about a scene, including information about occluded or distant regions of the scene, than is available from the local data. 1. A system , comprising:a display device; and one or more processors; and', obtain sensor data for an environment of a real-world scene captured by one or more sensors;', 'render virtual content for the environment based at least on the sensor data and pre-generated three-dimensional (3D) mesh data for the environment;', 'determine one or more colors or lighting information of a region of the environment on which the rendered virtual content is to be projected;', 'modify one or more colors of the virtual content based at least on the determined one or more colors or lighting information of the region; and', 'provide the virtual content to the display device., 'a memory storing instructions that, when executed on or across the one or more processors, cause the one or more processors to], 'a controller comprising2. The system of claim 1 , wherein the memory further comprises instructions that claim 1 , when executed on or across the one or more processors claim 1 , cause the one or more processors to:determine a surface normal of a surface within the region of the environment;determine direction of light from a light source in the environment;determine that the surface ...
