Abstract: In one embodiment, accurate onsite model visualization is provided by utilizing a user's location and orientation in the physical environment to control a view of a CAD model (and optional aligned point cloud), enabling the user to perceive the relationship between model data and locations in the physical environment. Instead of augmenting a view of the physical environment with virtual features, the user navigates within a virtual environment (consisting of the CAD model and optional point cloud) based on their movements in the physical environment. Based on such navigation, the user may determine when they have moved to a location in the physical environment that they would like to interact with (e.g., a location to mark), and interact with such location based on related model data.
