Interface-based modeling and design of three dimensional spaces using two dimensional representations are provided herein. An example method includes converting a three dimensional space into a two dimensional space using a map projection schema, where the two dimensional space is bounded by ergonomic limits of a human, and the two dimensional space is provided as an ergonomic user interface, receiving an anchor position within the ergonomic user interface that defines a placement of an asset relative to the three dimensional space when the two dimensional space is re-converted back to a three dimensional space, and re-converting the two dimensional space back into the three dimensional space for display along with the asset, within an optical display system.

Systems and methods for analyzing tread surface data to assess tire tread parameters, such as irregular wear characteristics of a tire tread, are provided. For example, tread surface data, such as a tread surface map, can be processed to generate a convex hull for the tire. The convex hull can approximate the convex outer surface of the tire. The convex hull can be used as a reference for analyzing the tread surface data. In particular, irregular wear zones in the tire tread can be mathematically concave relative to the convex hull. Comparing the tread surface data to the convex hull can reveal information indicative of irregular wear characteristics of the tire. For instance, the local depth of the measured tread surface data relative to the convex hull can provide a quantitative measure of irregular wear characteristics of the tire.

Embodiments described herein relate to an augmented expression system to generate and cause display of a specially configured interface to present an augmented reality perspective. The augmented expression system receives image and video data of a user and tracks facial landmarks of the user based on the image and video data, in real-time to generate and present a 3-dimensional (3D) bitmoji of the user.

A data processing method, apparatus, device, and medium are provided. The method may include obtaining a set of edges marked as usable for cutting from a two-dimensional mesh model, searching the set of edges to obtain a cut path set, calculating, for each candidate cut path in the cut path set, a path length, and calculating a structural evaluation value corresponding to the candidate cut path. The method may further include calculating a cut evaluation estimate of each candidate cut path based on the path length and the structural evaluation value, selecting one candidate cut path as a target cut path according to the cut evaluation value, and cutting the two-dimensional mesh model into at least two sub-models using the target cut path, where the at least two sub-models may be used for generating a texture unwrapping result of the two-dimensional mesh mode

The invention notably relates to a method for performing a 3D structural restoration of a geological setting with a computer system, including unfolding one or more geological surfaces of the geological setting. The unfolding comprises for each respective geological surface providing a 3D triangulated surface representing the respective geological surface, and determining a conformal flattening that transforms the 3D triangulated surface into a 2D triangulated surface. The conformal flattening is an iso-topographic mapping which substantially preserves angles. This provides an improved solution of 3D structural restoration of a geological setting.

A method is provided for generating a three-dimensional morphable model of an element from an initial database of examples of such elements providing data allowing, for each of the elements of the initial database, a three-dimensional meshed surface based on points and on a triangular network connecting the points to be determined.

Methods for creation and use (e.g., for navigation) of displays of flattened (e.g., curvature-straightened) 3-D reconstructions of tissue surfaces, optionally including reconstructions of the interior surfaces of hollow organs. In some embodiments, data comprising a 3-D representation of a tissue surface (for example an interior heart chamber surface) are subject to a geometrical transformation allowing the tissue surface to be presented substantially within a single view of a flattened reconstruction. In some embodiments, a catheter probe in use near the tissue surface is shown in positions that correspond to positions in 3-D space sufficiently to permit navigation; e.g., the probe is shown in flattened reconstruction views nearby view regions corresponding to regions it actually approaches. In some embodiments, automatic and/or easily triggered manual view switching between flattened reconstruction and source reconstruction views is implemented.

The present invention relates to improvements to systems and methods for determining a current location of a client device, and for identifying and selecting appropriate geo-fences based on the current location of the client device. An improved geo-fence selection system performs operations that include associating media content with a geo-fence that encompasses a portion of a geographic region, sampling location data from a client device, defining a boundary based on the sampled location data from the client device, detecting an overlap between the boundary and the geo-fence, retrieving the media content associated with the geo-fence, and loading the media content at a memory location of the client device, in response to detecting the overlap.
