Abstract: Provided is a process including obtaining runtime environment properties of a client computing device and selecting a set of software libraries for use by an AR engine based on the runtime environment properties, determining a request including an identifier of an AR content template, and determining a response including a three-dimensional model of the AR content template. The AR engine causes the client computing device to obtain an image of a real-world environment, obtain a virtual representation of the real-world environment by using the set of software libraries, and render the three-dimensional model overlaid on a presentation of the real-world environment on a visual display. The AR engine also can cause the client computing device to detect a change in a pose and update the three-dimensional model on the visual display based on the change in the pose.
