An augmented reality (AR) game system hosted and executed on a mobile client enables occlusion of AR game elements by objects in the real world. The mobile client captures a camera view of an environment including a real-world object. The AR game system identifies a cluster of feature points associated with the real-world object and generates a mesh from the cluster. The AR game system represents the mesh on a virtual coordinate plane, such that an AR game element can appear to interact with the real-world object. The AR game system renders, on the mobile client, the AR game element to appear as though it is occluded by the real-world object.
