Apparatuses, systems, and techniques for constructing a data structure to store a shape of an object based at least in part on a portion of multiple images, and obtaining poses of the object by tracking a pose of the object through the multiple images based at least in part on the data structure. Optionally, the poses may be used to generate a plan for a path of a device to travel, generate a rendering of at least a portion of a Mixed Reality (“MR”) display to be viewed by a user, and/or the like.
