The disclosed technologies identify opportunities to display relevant three-dimensional (“3D”) model data within a real-world environment as a user wears a wearable device. The 3D model data can be associated with objects, or items, and the 3D model data rendered for display is relevant in the sense that the items are determined to be of interest to the user and the items fits within the real-world environment in which the user is currently located. For instance, the techniques described herein can recognize items typically found in a kitchen or a dining room of a user's house, an office space at the user's place of work, etc. The characteristics of the recognized items can be identified and subsequently analyzed together to determine preferred characteristics of a user. In this way, the disclosed technologies can retrieve and display an item that correlates to (e.g., matches) the preferred characteristics of the user.
