A method and an apparatus for tracking an entity based on feature data independent of an augmented reality engine are provided. A URI for feature data of an entity is generated from a combination of a name of the entity and a name of an AR engine, feature data of the entity representing characteristics of the entity is acquired in a format capable of being processed by the AR engine by using the URI, the entity is tracked in an augmented reality space by executing the AR engine based on the acquired feature data, and thus, an entity based on feature data independent of an augmented reality engine may be tracked.

Method and apparatus for tracking entity based on feature data independent of augmented reality engine

The present invention relates to a method and a system for three-dimensional automatic scan based primitive, and estimates a three-dimensional model of an object from three-dimensional scan data of the object, recognizes a shape of the three-dimensional model by using fitting with at least one primitive, evaluates confidence of each of surface points of the three-dimensional model based on similarity between the at least one primitive used for shape recognition and the shape of the three-dimensional model, and scans the object in a series of views determined based on the confidence of each of the surface points, and thus, accuracy of the three-dimensional scan of the object is improved and time required for scan may be reduced.

Relating to an the integrated rendering method for various extended reality modes and a device having thereof, loading an XR-scene content including at least one virtual object content representing an extended reality image from a storage and representing a virtual object included in the extended reality image; inputting a selection, from a user, of any one extended reality mode among a plurality of extended reality modes including a virtual reality mode and an augmented reality mode; and maintaining or converting a property of each of a plurality of rendering options for at least one virtual object content according to the selected extended reality mode, and rendering at least one virtual object content having the maintained or converted property. Therefore, a virtual reality image and an augmented reality image can be generate from one XR-scene content.

Disclosed is a device and method for representing HTML elements having three-dimensional (3D) information on web, the device including a virtual space providing unit configured to provide a 3D virtual space that is displayed on the web, and an HTML element placing unit configured to place an HTML element that is displayed in a 3D layout on the 3D virtual space, based on an HTML document.

Device and method for representing HTML elements having 3-dimensional information on web

A method for supporting 3D printing includes identifying a product, searching and providing a 3D model present on a web in relation to the identified product, calculating and simulating suitability between the identified product and the searched 3D model based on information of the identified product and the searched 3D model, and transmitting the 3D model information to a 3D printer to produce the 3D model. Accordingly, the 3D printing technique may be actively utilized for DIY in various fields, business models or the like.

Terminal and method for supporting 3D printing, and computer program for performing the method

Disclosed is a system for authoring and providing augmented reality contents, which includes a database storing a plurality of place models expressing an inherent physical place, a positioning unit for determining a current position of a user, a place model processing unit for searching and loading a place model corresponding to the current position of the user from the database, and a virtual object processing unit for disposing a virtual object expressed through a HTML document at a predetermined location in the loaded place model, wherein the plurality of place models is hierarchically stored so that at least one place model has at least one another place model of a subordinate concept.

System for authoring and providing augmented reality contents

Disclosed is a content management method, which includes obtaining data for a content including a plurality of point-of-interest (POI) and a plurality of POI documents associated with each of the plurality of POIs, obtaining at least one level-of-detail (LOD) information which allows the content to be displayed according to an interest of the user, and determining a display format for the content based on the LOD information. Here, the LOD information may include information for the interest level of the user with regard to the content, and the interest level may be independent from a scale level of a map at which the content is displayed.
